Description

The invention relates to a load loading crane, in particular Container loading crane, comprising one in a transfer direction extending crane bridge, a first lifting unit, a second lifting unit, which is in the transfer direction from the first Lift unit is arranged at a distance, the first Lifting unit and the second lifting unit each have at least one Have hoist with assigned load handler, and a transfer unit arranged between the lifting units, the transfer unit and the lifting units being designed in this way are that between each of the lifting units and the Transfer unit loads can be exchanged.

Such a load loading crane is, for example, from DE-PS 19 06 212 known. The well-known crane is used for loading and unloading used by container ships. For unloading a container ship lifts the first lifting unit, the so-called water or ship cat, a container from the cargo hold of the Ship and passes it to a movable on the crane bridge Transfer unit (in container language also as Called "transfer cat"). The transfer cat hands it over Container on land to the second lifting unit, the so-called Land cat, which then places the container on land, while the transfer trolley returns to the first lifting trolley.

The working time for loading and unloading load carriers, such as container ships, has so far been limited both lifting trolleys. For example, when loading the container ship time required for lowering by the ship's cat a container, for uncoupling the load handler from this container, for the transfer of the load handler to another container, for coupling the load handler to this additional container and to lift the additional one Containers to the transfer cat were usually longer than the travel time required by the transfer cat from the Ship cat to the land cat and back to the ship cat including the respective handover times. As a result of progressive technical improvement of the lifting trolleys as well the aid for instructing a container to be dropped and to instruct the load handler on a person to be picked up However, containers have become these conditions changed to the disadvantage of the transfer cat, which now represents the factor limiting working hours.

It is therefore an object of the invention, a generic To provide load loading crane with which the working cycle times for loading and unloading load carriers, such as For example, container ships can be further reduced.

This object is achieved in that that facing away in the transfer direction of the first lifting unit A conveyor unit is provided on the side of the second lifting device is, the conveyor unit and the second lifting unit are designed so that loads can be exchanged between them can be, and wherein the conveyor unit at least has a delivery / acceptance point for loads.

By the upstream or downstream of the second lifting device The conveyor unit is the one to be covered by the transfer cat Transfer path shortened with corresponding shortening the transfer times between ship and land cat, as a result the working time of the cargo loading crane shortened.

To increase the loading and unloading rate in the area of the conveyor unit, it is proposed that the conveyor unit at least two conveyor lines, each with a delivery / acceptance point for loads. For a side-by-side arrangement to enable a number of cargo loading cranes on the quay it is further proposed that the at least two Conveyor lines are arranged one above the other.

A conveyor line can have, for example, a conveyor platform, the rails extending in the transfer direction is movable. In a simple and inexpensive to manufacture Embodiment, the conveyor platform of one be fixed plate formed by means of attached Rolling on the rails is movable.

If at least one of the conveyor lines has a return path is assigned, which is essentially parallel to the conveyor line runs and for return not with a load loaded conveyor platforms, so this conveyor line equipped with a plurality of conveyor platforms be cyclical with the aid of the return path circulate. Through this measure, the conveyor line can be next the conveying function also functions as a buffer to balance the delivery rates of the cargo loading crane and one downstream of the delivery / acceptance point for loads Take over transport equipment. This can advantageously at both ends of the conveyor section and return section a transfer device may be provided in order to relocating at least one conveyor platform from the conveyor line on the return path or vice versa.

The fact that the conveyor unit above the load loading crane load-bearing surface is arranged, the Basic level, i.e. the underground carrying the load loading crane, essentially kept free and, for example, in the event of a fault or failure of the subordinate to the delivery / acceptance point for loads Transport device, to maintain a Emergency operation. In addition, a essentially free basic level, the implementation of a special operation, For example, the reloading of urgent loads directly from the loading crane to trucks or the like ..

To enable an exchange of burdens between the Load loading crane carrying underground and the conveyor unit the load loading crane can have an additional lifting unit, for example. The additional lifting unit is advantageous here Slidable in the transfer direction.

The second lifting unit can be moved in the transfer direction be trained. This enables implementation if necessary offsets by the width of one or more Loads, e.g. when exchanging loads with the transfer unit, which will be discussed in more detail below. A This results in a particularly simple construction if the second lifting unit on one provided on the crane bridge Transport path is displaceable in the transfer direction. Alternatively the second lifting unit can, however, also in the transfer direction be immovable, which saves costs enables because the second lifting unit has no horizontal drive needed. Through a fixed arrangement of the second lifting unit the first lifting unit can be attached to the load loading crane if necessary be moved past the second lifting unit. The latter is, for example, in the case of container loading cranes used in freight ports for storing the older ones in container ships The design of the existing hatch cover is an advantage.

For example, pendulum movements of the Load handler of the second lifting unit before its approach to prevent the conveyor unit and thus a precise placing or taking up of a load on the or to be enabled by the conveyor unit, it is proposed that instruction areas on the cargo loading crane arranged for the load handling device of the second lifting unit are. Alternatively or additionally, you can use the cargo loading crane Guide means for the load handler of the second Lifting unit can be provided for such pendulum movements to exclude from the outset essentially.

In order to transport the loads as quickly as possible to be able to achieve or from the cargo loading crane suggested that the burdens at the delivery / acceptance points from an essentially continuously conveying transport device taken over or on an essentially steady promoting transport device are given.

At the working times of the loading crane for loading and To be able to further reduce unloading of load carriers provided that the transfer unit has a load receiving area having a load bearing surface and that the An operating device is assigned to the load suspension area, by means of which the load bearing surface can be exchanged with a front of the lifting units in a forward direction between a transfer position and a front operating position is adjustable and to exchange loads with a rear of the lifting units in a reverse direction between the transfer position and a rear operating position is adjustable. During a rendevous maneuver by the transfer unit of the load loading crane according to the invention with the front lifting unit brakes the transfer unit immediately next to this lifting unit. Then the lifting unit has its lifting gear raised to the highest position, the operating device moves and transfers a load to the hoist or takes on a load of this. The operating device then moves back into the transfer unit. Subsequently or at the same time the transfer unit starts the Transfer to the other lifting unit.

Since only the operating device is extended and retracted needs to be, must in the inventive Load loading crane for handing over or taking over a load does not accelerate the entire mass of the transfer unit will. The acceleration of the much smaller mass of the Operating device requires less time, which means shorter working cycle times results, and also saves also energy traditionally used to accelerate the big Masses had to be spent. In addition, the equipment points the transfer unit with an operating device too control advantages because the control of the movements the transfer unit and the lifting units of the lifting units unbundled, i.e. made independently can be. As described above, a conventional cargo loading crane the transfer unit in front of the brake the respective lifting unit, raise fully wait for the load suspension device and finally until move exactly under the lifting unit, i.e. the movement the transfer unit must respond to the movement of the hoist Lifting unit coordinated. Moves according to the invention the transfer unit immediately up to its end position the lifting unit. If the hoist has its end position, i.e. reached its highest position, it is followed by a corresponding one Signal extended the operating device.

This can further shorten the working cycle times achieved that the transfer unit has at least two load receiving areas with one load bearing surface each has, the load-bearing areas arranged in this way and / or are trained so that each of them can be handed over loads from the lifting units to the load bearing surface and to take over loads by the lifting units from the Load bearing surface (in the following for short: load exchange with the lifting units) interact with each of the lifting units can.

With regard to single-cat cranes has been in loading circles already thought about it in the so-called double game mode to use. This means an establishment where the load carrier is loaded and unloaded at the same time will, i.e. an operation in which the one lifting and Transfer unit initially picks up a load to be unloaded and it unloads and immediately afterwards one to be loaded Picking up the load and conveying it to the load carrier.

Through the above-mentioned training according to the invention the transfer unit can each one of the lifting units Meet with the transfer unit first of all from her Pass the carried load into a first of the receiving areas and then regardless of that from the transfer unit Remove the delivered load from the second pick-up area.

So both the lifting unit and the transfer unit come loaded to the meeting point, exchange their loads there and leave the meeting point loaded again.

In this embodiment, the transfer unit with at least two load receiving areas with the exchange of loads to be able to carry out both lifting units more quickly, it is proposed that at least one of the load bearing areas has an operating device by means of which Load bearing surface for the exchange of loads with a front of the lifting units in a forward direction between one Transfer position and a front operating position adjustable is and to exchange loads with a rear the Lifting units in a reverse direction between the transfer position and a rear operating position adjustable is. The time saved results from the fact that the offset runs required for the exchange of loads, where the large mass of one of the units is moved must be largely avoided and only that mass to be moved of the respective load is moved anyway.

In one embodiment, the operating device is for everyone Container loading cranes according to the invention proposed that this at least one extendable element with one on the Transfer unit attached base part and at least one telescoping forward and relative to the base Backwards adjustable telescopic part. The In this case, the load-bearing surface can face away from one of the base part Surface of the telescopic part can be formed.

In an alternative embodiment, the operating device have a platform that is on in the forward direction and projecting backward from the receiving area Rail is extendable. This embodiment draws due to the fixed rails due to special high stability.

In the alternative embodiment of the operating device the platform can be formed by a solid plate, the extendable on the rails by means of attached rollers is, the load bearing surface from an upper horizontal surface of the solid plate is formed is. Using such a platform results in a stable, yet space-saving design of the operating device. In principle, however, it is also possible that the platform from an endless belt drawn around a guide body is formed by means of roller elements on the rails is extendable, the load bearing surface from an upper horizontally extending part of the endless belt formed is.

To the container loading crane, which can be operated in double play the number of necessary to exchange loads To be able to reduce misalignment as far as possible provided in a first embodiment of the transfer unit, that the two load-bearing areas are arranged one above the other are, at least the lower load bearing area, preferably both load suspension areas, one operating device having.

In an alternative embodiment of the transfer unit it is provided that the two load-bearing surfaces relative to the assigned load-bearing areas are together and relative to the transfer unit a substantially horizontally extending axis can be pivoted are, their orientation relative to Maintain transfer unit.

In a further alternative embodiment of the transfer unit can the two load bearing surfaces on one in essentially horizontal and by a substantially vertical rotating axis fixed turntable be.

As an alternative to a cargo loading crane, its transfer unit has at least two load receiving areas, can with a freight loading crane that can also be operated in double play the transfer unit has a load handling area have, wherein each of the lifting units at least two hoists, each with an assigned load handler are assigned, each with the load bearing area for transferring loads to the load bearing surface and for Interaction of loads from the load bearing area can be indifferent whether the other, the same Lifting unit assigned to the lifting unit has picked up a load or not. Through these measures, each of the lifting units at a meeting with the transfer unit, first with the the load handler is currently emptying the one it has delivered Take the load from the load suspension area and then the one carried by the other load handler Transfer the load to the receiving area. So you can also use the load loading crane load carrier described above, such as container ships, in double-game operation at the same time be loaded and unloaded.

In all of the embodiments of the cargo loading crane described above can the transfer unit in the transfer direction be slidable. This has the advantage that the distances to be covered on all three units, lifting units and transfer unit, can be divided with corresponding time savings. A particularly simple structure this results if the transfer unit is on an intermediate the transport rail running along the longitudinal ends of the crane bridge is displaceable in the transfer direction.

However, it is also possible that the transfer unit in Transfer direction is designed to be immovable. At this Embodiment also uses the transfer function of the two Lifting units taken over. This can be done in a simple way in that the transfer unit on the crane bridge, For example, is firmly arranged on the lower cross members. Alternatively, however, it is also possible for the transfer unit on a surface supporting the load loading crane in one which is essentially orthogonal to the transfer direction Direction is arranged movable. In both cases the transfer unit can load the crane at its Movement along the quay, i.e. crthogonal to the direction of cat travel, consequences. But even a fixed arrangement on the the underground carrying the load loading crane is conceivable.

In another aspect, the invention relates to a Procedure for transporting loads between two horizontally spaced load areas, in the two load areas the loads raised and at least each by belonging to a first one of the load shedding areas Load handling and transport system along a first section and by at least one of a second one of the load storage areas associated load handling and transport system are transported along a second section, wherein between the two sections a handover from the first Load suspension and transport system to the second load suspension and transport system using an intermediate carrier system takes place, and being used to transport the Loads along at least one of the first and second sections in addition to the respective load bearing and Transport system an additional conveyor system is used. At the inventive method is through the use of additional conveyor system for the exchange of loads between the two load and transport system to be covered and thus also the duration of the work cycle which determines the transport rate of the process shortened. As load lifting and transport systems can, for example, the lifting units described above, as the intermediate carrier system that described above Transfer unit and as an additional conveyor system the above described conveyor unit can be used.

In Figure 1a is a generally designated 10 container loading crane for simultaneous loading and unloading of container cargo ships in double game mode as an example for shown a cargo loading crane according to the invention.

The container loading crane 10 comprises a along a quay 12 Crane frame 14 movable on rails 12a, on which a crane bridge 16 is attached. At quay 12 is a Container ship 18, the one arranged in stacks 20 one above the other Contains container 22. The containers 22 are in figure la with its narrow end view. Your longitudinal direction extends with the longitudinal direction of the ship 18 perpendicular to the plane of the drawing. Furthermore, in FIG Containers 22 that are unloaded from container ship 18 should or have already been unloaded (hereinafter briefly: unloading container), with a small one facing right Arrow marked, whereas the container 22 with which the container ship 18 is to be loaded or already loaded was (in short: loading container), with a small arrow pointing to the left.

The crane bridge 16 of the container loading crane 10 has one shore-side part 16L and a water-side boom 16W on. As shown in particular in Figure 1b, the Crane bridge 16 two substantially parallel to each other Bridge girders 16a and 16b, which have several connecting webs 16c are interconnected. At the top the bridge girders 16a and 16b are rails 24a and 24b on which a land trolley 26 (hereinafter also briefly: Landkatze 26) and a water-side Trolley 28 (hereinafter also briefly: water cat 28) are freely movable.

On the opposite sides of the bridge girders 16a and 16b are runners 30a and 30b for one thereon freely movable transfer trolley 32 is provided. The running tracks 30a and 30b extend from the left in Figure la shown water-side end 16W of the crane bridge 16 to to the landward end 16L shown on the right in FIG the crane bridge 16 in a transfer direction W / L.

The water trolley 28 comprises a chassis 28a, on which a hoisting rope system is arranged. The hoisting rope system is like is not shown in detail in the pulleys of the chassis 28a looped in and is driven by a motor. Lifting rope system and motor together form a water side Hoist 28b. There is a container detection frame on the lifting mechanism 28b 28c (in container language too Called spreader) attached, which is designed in this way is that by means of (not shown in the figures) Couplings grip the container at its four upper corners can. The movement of the water cat 28 on the running rails 24a and 24b and the operation of both the hoist 28b and the spreader 28c can also be operated by an operator from a driver's cabin 28d from control lines, not shown being controlled.

When the hoist 28b is caught or released by the engine becomes, the spreader 28c rises or falls. If the chassis 28a along the boom with the engine stopped 16W is moved, the height of the Spreaders don't. The for driving along the 16W boom required driving performance of the water cat 28, for example. via so-called cable garlands or a sliding contact rail (both not shown) are supplied.

The water trolley 28 usually runs along the boom 16W only those movements that are necessary to the horizontal position of that carried by the lifting mechanism 28b To adapt spreaders 28c to the various container stacks 20, i.e. Offsets usually only one Stack width.

The land cat 26 has a water cat 28 corresponding Structure on, i.e. the land cat 26 also has a chassis 26a, a lifting mechanism 26b arranged thereon with a spreader 26c and a driver's cabin 26d (see Figure la). Also corresponds essentially to the operation of the land cat 26 that of the water cat 28.

To the lifting distances for the hoists 28b and 26b between the container ship 18 and crane bridge 16 or between quay 12 and To keep crane bridge 16 as small as possible is the Crane bridge 16 adjustable in height relative to the crane scaffold 14 educated.

The horizontal transport of the containers 22 along the crane bridge 16 is shown in that in Figures 1a and 1b Embodiment on the one hand of the transfer cat 32 and others taken over by a conveyor unit 64. The conveyor unit 64 comprises an upper conveyor section 64o and a lower one Conveyor line 64u, which for reasons of saving space are arranged one above the other.

As is shown in particular in FIGS. 1a and 1b, is each conveyor line 64o, 64u on their land side End 16L of the crane bridge 16 end facing a transfer device 66 assigned. The transfer device 66 comprises a slidable along a horizontal transport path 66a Spreader 66c, which uses a short-stroke hoist 66b can be raised and lowered to container 22 by an elevated two-storey railroad track 68 take over and on the respective conveyor line 64o or 64u to drop or vice versa from one of the conveyor lines 64o or 64u to take over and set down on the railroad track 68.

The rail track 68 includes the upper and lower conveyor lines 64o and 64u respectively, an upper rail level 68o and a lower rail level 68u with three each essentially orthogonal in the area of the container loading crane Rail tracks running to the transfer direction W / L 68o1, 68o2, 68o3 or 68u1, 68u2, 68u3. The rail levels 68o and 68u are by means of a scaffold structure 68a in two floors one above the other, including the lower one Rail level 68u above the container loading crane 10 bearing base 12 is arranged.

By arranging both the lower conveyor section 64u and also the lower rail level 68u above quay 12 remains the basic level, i.e. the quay 12, essentially free and can be used to maintain emergency operation, for example Failure of the rail conveyor track 68 can be used. About that in addition, the essentially free basic level enables Execution of a special operation, e.g. the unloading of Containers directly from the container loading crane, e.g. to be loaded onto trucks. This is followed in Connection with the description of Figure 14 even closer To be received. Also on the structure and function of the Railroad track 68 is discussed in more detail below will.

At the water-side end of the conveyor lines 64o and 64u In each case an instruction device 72 is provided, which any pendulum movements of the Spreaders 26c of the land cat 26 before approaching the to prevent the respective conveyor section 64o or 64u.

In the following, the structure and Function of the conveyor unit 64 using the example of the upper conveyor section 64o are explained in more detail.

The upper conveyor section 64o comprises a conveyor platform 64o1, which by means of rollers 64o2 in rails 64o3 in the transfer direction W / L are led. The rollers 64o2 are by means of a drive 64o4, for example an electric motor. In principle, however, an electromagnetic drive can also be used Linear conveyor technology or the like can be used. The rails 64o3 are of two profile beams 64o5 with in essential U-shaped cross section formed, which with the Base leg of the U-shape on horizontal beams 14o of the crane scaffold 14 are attached so that the open sides of the U-shape are facing each other. To prevent the platform from falling out Prevent 64o1 from the rails 64o3 are the profile beams 64o5 on both ends using end plates 64o6 closed.

The attached to horizontal beams 14u of the crane frame 14 lower conveyor section 64u is the upper conveyor section 64o trained analogously. The distance D, in particular the profile beam 64o5 must be dimensioned such that the spreader 26c the land cat 26 can be moved between them, to deposit a container 22 on the lower conveyor line 64u or to take a container 22 of this.

To also transport containers 22 with the conveyor unit 64 to be able to use the self-locking twist locks (so-called "semi-automatic twist-locks") are equipped, such as for example, it is common for securing containers to the deck are the conveyor platforms of the conveyor lines 64o or 64u with recesses (see, for example, the one in FIG. 2a shown recesses 64o7 of the conveyor platform 64o1 upper conveyor section 64o). In these recesses, the Twist locks of a container 22 are added without that the container 22 interlocks with the conveyor platform would.

If one uses the movability of the land cat 26 in the transfer direction W / L off, each of the conveyor lines 64o and 64u, of course, also with more than one funding platform (e.g. 64o1).

It should be noted that apart from that in the above conveyor 64 shown in the figures described any type of conveyor can be used as well can which is an exchange of containers 22 with the Country cat 26 on the one hand and the transport device 68 on the other hand allowed.

In Figure 2c is a schematic plan view of the container delivery / acceptance point the upper conveyor section 64o shown. In the snapshot shown in Figure 2c is an unloading container delivered from the upper conveyor section 64o 22 from the spreader 66c of the transfer device 66 has been added. The funding platform 64o1, from that can only be seen in FIG. 2c the water-side end is already on the way back to the land cat 26 (see Figure 1a). On the 68o1 track of the upper one A transport carriage 70 is already available at rail level 68o, to which the container 22 from the transfer device 66 will be parked.

In Figure 2c you can also see another, with a Container 22 loaded transport carriage 70 ', which is on the middle rail track 68o2 moved in the direction of arrow C. Between adjacent rail lines 68o1 and 68o2 or 68o2 and 68o3 crossovers 68o4 are provided, which is a transfer of the trolleys 70 from one allow on the other track.

The rail tracks 68o1 and 68u1 can, for example, as a parking lane are referred to, the rail tracks 68o2 and 68u2 as acceleration or delay track and the rail tracks 68o3 and 68u3 as a transport track. On the parking lane 68o1 or 68ul, the trolleys 70 come in the area of the transfer devices 66 standstill waiting for loading or unloading a container 22. after loading with one The transport carriage 70 travels container 22 in the parking lane 68o1 or 68u1 and then changes to the acceleration lane 68o2 or 68u2. The trolley 70 is accelerated there, until it has the same speed as that steady stream of moving on the transport track Transport trolley 70, whereupon he then with another Lanes change in this steady stream and for example an interim storage facility for containers. The Delivery of a container 22 from the intermediate storage to one respective container loading crane 10 is carried out in an analogous manner under appropriate lane changes with braking of the trolley 70 on the delay track 68o2 or 68u2 and stop this trolley in the parking lane 68o1 or 68u1.

Rail sections 68o1, 68o2 and 68o3 of the upper rail level 68o are roughly schematic in FIG. 2c only as simple solid lines are shown. This is supposed to be hinted that basically any kind of essentially steadily conveying transport device 68 used no matter what technology to promote the container 22 along the tracks and to switch between the traces is actually used. Furthermore, the number the traces of the transport device 68 not on the in the Drawing shown three tracks set. It can more or fewer tracks are also provided. Important is just that the individual container in essentially continuously transported away from the container loading crane be or can be transported there.

Advantageously, the transport device 68, such as shown in the exemplary embodiments, at least two Transport levels 68o and 68u, one of which 68o to Transport of unloading containers and the other 68u to Transport of loading containers is used. Hereby becomes the simultaneous loading and unloading of the container ship 18 enabled in double play. Because of Space saving in the breadth dimension, i.e. along the quay wall, it is also advantageous to use the two transport levels 68o and 68u to be arranged one above the other. Are also located both transport levels above the container loading crane load-bearing subsoil, this basic level can be used for implementation a special operation or for maintenance an emergency operation.

The structure of an embodiment of the Transfer trolley 32 will be explained in more detail with reference to Figure 3a becomes.

The transfer trolley 32 has two vertically running side walls 32a, the two spaced-apart horizontal connecting floor 32b with each other are connected. The two side walls 32a and the two connecting floors 32b enclose a lower one Container receiving area 32u. Also includes the transfer cat 32 an upper container receiving area 32o, the above the upper connecting floor 32b and between the Side walls 32a is arranged. In the container reception areas 32u and 32o can container 22 for transport be taken along the crane bridge 16. On the top Chassis 32c are arranged at the ends of the side walls 32a, by means of which the transfer trolley 32 on the running rails 30a and 30b can be moved horizontally.

In both receiving areas 32u and 32o there is one out of one A plurality of telescopic forks 34 existing control device 36u and 36o provided. Under the term "operate" is both the takeover of a container 22 from one the lifting trolleys 26 and 28 and its transfer into one of the Recording areas 32u and 32o as well as the transfer of a Containers 22 from one of the receiving areas 32u and 32o and understood its transfer to one of the lifting trolleys 26 or 28. To exchange loads with the water cat 28, the Operating device 36u or 36o between one in FIG. 3a shown transfer position and one shown in Figure 3b water-side operating position can be adjusted in which the operating device in the direction of arrow W. the transfer trolley 32 is extended. For container exchange with the land cat 26, the operating device 36u or 36o between the transfer position shown in Figure 3a and an onshore operating position be in which the operating device in the direction of Arrow L is extended from the transfer trolley 32.

As shown in Figure 3b, each of the telescopic forks is made 34 of the operating device 36u or 36o from one on the Transfer trolley attached lower guide rail 34a, one Intermediate element 34b and an upper guide rail 34c. On both sides of a longitudinal direction of the intermediate element 34b guide rollers 34b1 are attached, which are in guide grooves 34a1 and 34c2 of the guide rails 34a and 34c engage and together with them the telescopic ability provide the telescopic forks 34. Tops 34c1 of upper guide rails 34c together form a lower container placement surface 38u or an upper container surface 38o, on each of which a container 22 is parked can be.

For the sake of clarity is in the figures 3a and 3b, the drive of the telescopic forks 34 is not shown. This drive can, in a manner known per se, e.g. as a pneumatic or electromotive drive, or the like.

To take over an already raised container 22 from one of the lifting trolleys 26 or 28, for example, in the lower receiving area 32u, the transfer trolley 32 first moves in immediate vicinity of the lifting trolley. Then the telescopic forks 34 of the lower receiving area 32u into the water side or on-shore operating position extended, depending on whether the container 22 of the water cat 28 or the Landcat 26 is to be taken over. Next is the Container 22 by means of the lifting mechanism 26b or 28b of the lifting trolley 26 or 28 lowered until its lower edge 22a of the container contact surface 38u or 38o. After loosening and lifting the spreader 26c or 28c of the lifting trolley finally the container 22 by transferring the telescopic forks 34 in the transfer position in the receiving area 32u promoted.

When a container 22 is handed over to one of the lifting trolleys 26 and 28, respectively, are the steps described above executed in reverse order.

As is shown in particular in FIG. 1b, the container placement surface is 38o of the upper receiving area 32o in Vertical direction arranged lower than the lower edge 22a of a container 22 when this is from one of the lifting trolleys or 28 (in Figure 1b of the water cat 28) as far as possible was raised. This ensures that both Pick-up areas 32u and 32o from lifting jacks 26 and 28 can be operated equally.

The following is based on the rough schematic representations 9a to 9f the loading and unloading of the container ship 18 can be described in double-game mode.

The starting point here is a situation as shown in FIG 9a is shown. The water cat 28 has the Transfer trolley 32 has just taken over a loading container 22B and is about to lift the container 22B by means of the hoist 28b, which is indicated by an arrow I in FIG. 9a is. The transfer cat also has 32 from the water cat 28 an unloading container 22E 'in the upper receiving area 32o taken over and is on land travel, i.e. it moves along the crane bridge with the container 22E ' 16 towards the land cat 26, which is shown in FIG Arrow L is indicated.

The land cat 26 has a loading container 22B 'from the lower one Conveyor line 64u added and is currently to raise it by means of its lifting mechanism 26b, which is shown in FIG. 9a is indicated by an arrow II '. Meanwhile located a previously unloaded container from the land cat 26 22E already at the landward end of the upper conveyor line 64o and can from the spreader 66c of the transfer device 66 can be included.

According to FIG. 9b, the land cat 26 has the loading container 22B 'to a level of the lower receiving area 32u the transfer trolley 32 raised corresponding height. Further the transfer cat 32 was immediately connected to the land cat 26 approached. Now the lower operating device 36u Extended on the land side and the land cat 26 lowers the loading container 22B 'until it is on the lower container surface 38u gets up.

The water cat 28 has meanwhile unloaded the loading container 22B on the container ship 18 and is on a land-oriented offset travel by a stack width (arrow V _W in FIG. 9b) in order to take up the next unloading container 22E "with its spreader 28c.

The unloading container 22E is meanwhile the spreader 66c Transfer device 66 has been added and is together with this on the way (arrow To) to park lane 68o1 the upper rail level 68o, where there is already a transport carriage 70 is ready for him. Furthermore, on the parking lane 68u1 lower rail level 68u a transport carriage 70 with a another loading container 22B "stopped.

According to FIG. 9c, the spreader 28c of the water cat 28 turns on the discharge container 22E ". The spreader 26c of the Country cat 26 is released from the loading container 22B 'and the loading container 22B 'by means of the lower operating device 36u in the lower receiving area 32u of the transfer cat 32 caught up. Then the spreader 26c is ready raised as possible, the unloading container 22E 'by means of the upper operating device 36o from the upper receiving area 32o extended and the spreader 26c to the unloading container 22E 'coupled. Now the upper control device 36o caught up again.

Meanwhile, the upper transfer device 66 has the container 22E on the transport wagon waiting in the parking lane 68o1 settled and the lower transfer device 66 is located with the loading container 22B "on the way to the lower one Conveyor line 64u (arrow Tu ').

According to FIG. 9d, the transfer trolley 32 is located with the Loading container 22B 'on water, i.e. she moves with this along the crane bridge 16 onto the water cat 28 to what is indicated by the arrow W in FIG. 9d. At the same time, the land cat 26 lowers the unloading container 22E 'by means of their hoist 26b (arrow II). Meanwhile the water cat 28 lifts the unloading container 22E "by means of their hoist 26b (arrow I ').

The spreader 66c of the upper transfer device 66 is located on the way back to the upper conveyor section 64o (arrow To ') to wait for the next unloading container. Furthermore, the lower transfer device 66 has the loading container 22B "on the lower conveyor section 64u.

According to FIG. 9e, the water trolley 28 has lifted the unloading container 22E "as far as possible, ie to a height corresponding to the upper receiving area 32o of the transfer trolley 32. Furthermore, the transfer trolley 32 was moved directly to the water trolley 28. Now the upper operating device 36o becomes water-side extended and the water trolley 28 lowers the unloading container 22E "until it stands on the upper container mounting surface 38o. The water trolley 28 and transfer trolley 32 then begin a joint water-oriented offset travel by a stack width, which is indicated in FIG. 9e by an arrow V _W '. To carry out this offset drive, it is advantageous if the transfer trolley 32 can be releasably locked with the water trolley 28, so that a relative movement of the two trolleys 28 and 32 is prevented during the offset drive. Such a locking can also be provided between the land cat 26 and the transfer cat 32.

The land cat 26 has the unloading container 22E 'on the upper one Conveyor 64o turned off and its spreader 26c uncoupled from this.

The loading container 22B "is from the lower conveyor 64u for transfer to the land cat 26 in FIG. 9e conveyed to the left (arrow Fu) and the spreader 66c of the lower one Transfer device 66 is on its way back to Parking lane 68u1 of the lower rail level 68u (arrow Tu) to to wait for the next loading container there.

According to FIG. 9f, the spreader 26c of the land cat 26 is attached to the Loading container 22B "coupled. The spreader 28c of the water cat 28 is released from the unloading container 22E "and the unloading container 22E "by means of the upper operating device 36o in the upper receiving area 32o of the transfer cat 32 caught up. The loading container 22B 'is then moved on the lower operating device 36u from the lower receiving area 32u extended and the spreader 28c lowered and coupled to the loading container 22B '. Meanwhile Transfer cat 32 and water cat 28 their joint offset run ends and the lower operating device 36u becomes again caught up.

Meanwhile, the unloading container 22E 'is from the upper conveyor section 64o to the upper transfer device 66 funded (Pfeil Fo).

The double game loading and unloading cycle described above is repeated until the container ship 18th completely unloaded and loaded at the same time. Here is always when an unloading container stack 20 on the container ship 18 was completely removed, water cat 28 and transfer trolley 32 no common offset travel execute so that immediately with filling the resulting Gap with loading containers can be started.

FIG. 4 shows a second embodiment of a transfer cat shown, with analog parts with the same reference numerals are provided, as in Figures 1 to 3, however increased by the number 100.

Because the transfer trolley and lifting trolleys are generally designed in this way are that the transfer trolley is trouble-free on the lifting trolleys can be moved past if only the hoists of the Lifting jacks are essentially completely raised (cf. esp. Figure 1b), it is possible only the lower recording area 132u of the transfer trolley 132 with an operating device 136 to be provided (in the present case in the form of telescopic forks 134). In the upper receiving area 132o there are no controls.

The transfer of containers to the upper reception area In this embodiment, 132o can be made in style be that the transfer trolley 132 first directly under the respective lifting trolley is moved when this is a container has raised as much as possible. Then the container lowered by means of the lifting mechanism of the lifting trolley until the Container with its lower edge on the upper surface of the container 138o rests from the top of the top Connecting bottom 132b is formed. After loosening and lifting the spreader, the transfer trolley 132 can finally with the Container can be moved away again or the transfer cat 132 or the respective lifting trolley by an offset movement about a container width. To take over a Containers from the upper receiving area 138o become the Steps described above in reverse Order executed.

The mode of operation described above for the transfer trolley 132 is in principle also with the transfer cat 32 feasible according to FIG. 3a.

FIG. 5a shows a third embodiment of a transfer cat shown, with analog parts with the same reference numerals are provided, as in Figures 1 to 3, however increased by the number 200.

The embodiment according to FIG. 5a differs from the embodiments described above by the Structure of the operating device 236. The operating device 236 includes a roller table 242 with a roller table top 242a and rollers 242b attached to the bottom thereof, of which only one is shown in FIG. 5a. The rollers 242b can be driven by a drive, not shown an electric motor, for example. Furthermore, the operating device comprises 236 two profile beams 244 with a substantially U-shaped Cross-section that on the transfer cat 232 such are attached that the base leg of the U-shape of each Profile carrier 244 on an associated side wall 232a and one of the side legs of the U-shape on the connecting base 232b abut with the open sides of the U shape facing each other are arranged facing. The roller table 242 is dimensioned in such a way that he engages in the profile carrier 244 and the Rollers 242b on the abutting on the connecting floor 232b Stand up your thighs. So that the roller table 242 on the water side (Arrow W) and landward (arrow L) from the transfer cat 232 can be extended, the two profile beams are 244 on the water and land side via the side walls 232a of the Transfer cat 232 over. The length of the profile beam 244 is here dimensioned such that the roller table 242 for container exchange with one of the lifting trolleys 26 or 28 in an operating position, For example, the water-side shown in Figure 5b Operating position, can be extended. To fall out prevent the roller table 242 from the profile beams 244 to be able to, these are at both ends by means of end plates 244a closed. Figure 5c shows the transfer position of the roller table 242.

Although the operating device 236 in FIGS. 5a to 5c shown as assigned to the lower receiving area 232u it can also be used to operate the upper recording area be used if the profile carrier 244 is sufficient Have a distance A from one another (see FIG. 5a), that a container 22 together with coupled spreader 26c or 28c can be moved between them.

FIG. 6a shows a fourth embodiment of a transfer cat shown, with analog parts with the same reference numerals are provided, as in Figures 1 to 3, however increased by the number 300.

The embodiment according to FIG. 6a differs from the embodiment described above according to Figure 5a in that, instead of the roller table 242, an apron conveyor 346 engages in profile support 344 in a rolling manner, which correspond to the profile beams 244 according to FIG. 5a. Of the Plate conveyor 346 comprises a guide body according to Figure 6b 346a with two drive rollers 346b by one Drive, not shown, can be driven, for example. an electric motor. The drive rollers 346b are on each other spaced narrow sides of the guide body 346a with axes essentially parallel to each other arranged, the longitudinal ends of the drive rollers 346b in the profile carrier 344 engage. Around the drive rollers 346b and an endless belt 346c is tensioned on the guide body 346a. The endless belt 346c consists of a variety of Single plates 346d (Figure 6b), their dimensions in the axial direction the drive rollers 346b much larger than their dimensions is transverse to this axis and which is articulated are interconnected.

Due to the design of the plate conveyor 346 the Guide body 346a of the slat conveyor 346 only by the distance 1 / 2X (see Figure 6c) if the Endless belt 346c is to be moved by a distance X by one Container 22 from the water-side operating position according to 6b transfer into the transfer position according to FIG. 6c. The same applies to the transfer between shore-side Operating position and transfer creation. Therefore, the dimension Y 'of the slat conveyor 346 in the longitudinal direction of the profile carrier 344 be about twice the size Y of the Recording area 332u in this direction (see FIG. 6b). The plate belt conveyor 346 thus projects in its transfer position 6c on the land and water side from the respective Recording area. Because of this supernatant the operating device 336 is preferably only in the lower Recording area 332u used, although in principle it is possible to assign one to the upper recording area Belt conveyor operating device, for example, in the water-side operating position (analog Figure 6b) extend when the lower Received a container on the shore side or from this should be led away.

It should be noted that the above with reference to Figures 3a to 6c described different embodiments of Operating devices can be combined with one another as desired can. As an example here is just a transfer cat in which the upper recording area with a Telescopic fork control device according to Figures 3a and 3b and the lower with a roller table operating device according to figures 5a to 5c is equipped.

In Figures 7a and 7b, a fifth embodiment is one Transfer cat shown, with analog parts with the same Reference numerals are provided, as in Figures 1 to 3, however increased by the number 400.

The transfer trolley 432 comprises two side parts 432a, on the other lower ends 432a1 each have an elongated swivel bracket 448 by means of a pivot pin 450 about an orthogonal to the Transfer direction (double arrow W / L), horizontal Axis of rotation R (see FIG. 7b) is rotatably held. The pivot pin 450 passes through the swivel bracket 448 such that it divided into two legs 448a of essentially the same length becomes. Each of these legs 448a is at that Trunnion 450 facing away from another pivot 452 penetrates on which swing units 454 to the axis of rotation R essentially parallel axes are rotatably held. Each of the swing units 454 has a swing floor 454a and two swing side panels 454b for connection to the pivot pin 452. Further is a drive, not shown, is provided, by means of which the swivel supports assigned to the two side parts 432a 448 can be set in rotation (arrows B in FIG. 7a). As a result of this rotation, the two swings 454 pivoted about the axis of rotation R in the manner of a ferris wheel. The swings 454 are designed such that their center of gravity both in unloaded and in a container loaded state below that of the assigned pins 452 fixed pivot axis are arranged. Hereby it is ensured that the swing 454 automatically Maintain orientation relative to transfer cat 432.

When using the transfer cat described above 432 can exchange a loading container 422B and one Unloading container 422E between transfer trolley 432 and Water cat 428 can be done, for example, as explained below:

The transfer cat 432, on its lower at this time Swing 454 a taken over from the country cat, not shown Loading container 422B is arranged directly moved under the water trolley 428, which is lifted by 428b and spreader 428c an unloading container 422E as far as possible. This unloading container 422E will from the water cat 428 on the empty at this time upper swing set 454. Then the swivel bracket 448 by means of the drive, not shown, around the Rotation axis R rotated until the two swings 454 move their positions have exchanged. Now the loading container is located 422B carrying swing 454 in the up position and the swing carrying the 422E unloading container 454 in the lower position, so that the water cat 428 the Loading container 422B from the now upper swing 454 can take over. Finally, the transfer trolley 432 comes with the unloading container 422E again towards the land cat moves and the water trolley 428 lowers the loading container 422B into the container ship. The exchange of burdens with the Land cat is done in a similar manner.

FIGS. 8a and 8b show a sixth embodiment shown a transfer cat, with analog parts with are provided with the same reference numerals as in FIGS. 1 to 3, but increased by the number 500.

The transfer trolley 532 according to FIG. 8a differs from the transfer trolley according to Figure 7a in that the loading container 522B and unloading container 522E are not as above described in the manner of a ferris wheel by twisting about a horizontal axis of rotation R their positions swap, but like a carousel by twisting about a vertical axis of rotation S. This is the transfer unit 532 formed with a turntable 556 which over an axis or shaft 558 from which the side parts 532a of the Transfer trolley 532 connecting connecting base 532b around the Axis S is held rotatably. To be able to guarantee that the transfer trolley 532 remains stable on the crane bridge 516 can be moved if only with is loaded into a container, the chassis 532c is the Transfer trolley in the longitudinal direction of crane bridge 516 in particular long trained.

The takeover of the unloading container 522E from the water cat 528 and the transfer of the loading container 522B to the Water cat 528 are made according to the above on hand The procedure described in FIGS. 7a and 7b, however with the difference that to change the position of the container 522B and 522E now turntable 556 half a turn is rotated about the vertical axis of rotation S.

10a to 10e are used to build up and function of a second embodiment of a container loading crane are described, with analog parts are provided with the same reference numerals as in the figures 1 to 3, but increased by the number 600. The conveyor 664 is only roughly schematic in FIGS. 10a to 10e indicated and the transfer devices 66 and the transport device 68 are the clearer representation omitted for the sake of it. Regarding those parts Steps should be made to the description of Figures 9a to 9f.

Since the holds of container ships 618 to increase the Stability of adjacent container stacks 620 usually are provided with partitions 660, this applies above, in particular with regard to Figures 9a to 9f only for loading and unloading of the containers on deck. To the Loading and unloading of standing between the partitions 660 Containers, it is necessary to transfer after the transfer Set down the loading container, the empty spreader first Lift over the top of partition 660 and then lift it on the next unloading container. This takes time. A further reduction in crane play time can by using the in Figures 10a to 10e illustrated embodiment can be achieved. The container loading crane 610 differs from the container loading crane 10 according to Figure la in that the water cat 628 with two hoists 628b1 and 628b2 with assigned spreaders 628c1 or 628c2 is formed.

The following assumes a situation like this is shown in Figure 10a. The water cat 628 has from the transfer trolley 632 is currently carrying a loading container 622B the spreader 628c1 and is doing both hoists 628b1 and 628b2, which is shown in FIG Arrow I is indicated. Furthermore, the transfer cat 632 from the water cat 628 an unloading container 622E 'in the upper recording area 6320 and is located on Land travel (arrow L in Figure 10a). The land cat 626 has from the lower conveyor 664u a loading container 622B 'and raises it (arrow II' in FIG 10a). An unloading container previously deposited by the land cat 626 is already with the help of the upper conveyor 664o, the upper transfer device and the upper transport level been transported away.

The exchange of the shown in Figures 10b and 10c Containers 622E 'and 622B' between land cat 626 and the Transfer cat 632 is done in the same way as them above for the container loading crane 10 using the Figures 9b and 9c was explained on their description hereby reference is made to this.

The water cat 628 meanwhile has the loading container 622B dumped on container ship 618, the spreader 628c1 released and the spreader 628c2 to the next unloading container 622E "coupled.

According to FIG. 10c, the water trolley 628 lifts the spreader 628c1 and 628c2 and thus the unloading container 622E "(arrow I '). The spreader 628c2 with the unloading container 622E " here raised as much as possible, whereas the spreader 628c1 only up to the level of the lower exposure area 632u is raised, as shown in Figure 10d. Further 10d, the transfer trolley 632 is located with the loading container 622B 'on water travel (arrow W) and the Land cat 626 lowers the unloading container 622E '(arrow II).

According to FIG. 10e, the transfer trolley 632 is in this way on the water trolley 628 brought up that the unloading container 622E " on the spreader 628c2 already in the upper recording area 632o. The unloading container 622E "can thus simply by placing it on the surface 638o and loosening it of the spreader 628c2 to the upper receiving area 632o Transfer cat 632 are handed over, i.e. without extending the Operating device 636o in the water-side operating position. Simultaneously with the unloading container 622E " becomes the loading container 622B 'by means of the operating device 636u transferred to the water-side operating position, in which he then by coupling the spreader 628c1 from the Water cat 628 is taken over. The loading container 622B ' is already located directly above the container stack 620 ", on which the loading container 622B was last placed had been, so that the water cat 628 at the container loading crane 610 normally does not drive must perform.

The land cat 626 meanwhile has the unloading container 622E ' parked on the upper conveyor 664o. The lower one Conveyor 664u meanwhile has the next loading container 622B ".

The double game loading and unloading cycle described above is repeated until the container ship 618 completely unloaded and loaded at the same time. Here the water trolley 628 must always make an offset run run a stack width when an unload container stack 620 completely removed on the container ship 618 (in Figure 10e, this will next be the stack 620 ' be).

The structure and function of FIG. 11 are described below a third embodiment of a container loading crane are described, analog parts with the same Reference numerals are provided, as in Figures 1 to 3, however, increased by the number 700.

The container loading crane 710 differs from the container loading crane 10 according to Figure 1a in that instead the transfer trolley 32 which can be moved along the crane bridge 16 one under the crane 710 fixed on the quay 712 Transfer unit 732 is arranged and the land cat 726 and the water trolley 728 in addition to the lifting movements also the horizontal transfer the container to the only roughly schematic take over indicated conveyor 764.

The transfer unit 732 has a lower receiving area 732u, that of two vertical side parts 732a and two horizontal connecting bases 732b is enclosed and with an operating device 736 is equipped. The control device 736 can be any of those described above Have constructions. The upper receiving area 732o only has a floor in the form of the upper connecting floor 732b. Water cat 728 and land cat 726 show the same structure as the water cat 28 and the Country cat 26 of the container loading crane according to FIG. 1a.

In the following, the container loading crane 710 will briefly Loading and unloading of containers in double-game operation explained will. In a first step, the water cat takes 728 an unloading container 722E and transports it to the transfer unit 732, where it is in the upper receiving area 732o, i.e. on the upper connecting floor 732b, turns off (dash-dotted line (i)). Meanwhile the land cat 726 a loading container 722B from the lower one Conveyor line 764u added and him on the already operating device extended into the onshore operating position 736 of the lower receiving area 732u (dash-dot-dotted line (i)).

In a subsequent second step, the loading container 722B from the operating device 736 from the shore side Operating position transferred to the water-side operating position. The spreader 728c of the water cat 728 is from the top Recording area 732o to the lower recording area 732u moves where it holds the loading container 722B (dash-dotted Line (ii)) and the spreader 726c of the land cat 726 becomes the lower recording area 732u to the upper recording area 732o moves where it holds the unloading container 722E (dash-dotted line (ii)).

In a third step, the water cat 728 transports loading container 722B to container ship 718 and places him there (dash-dotted line (iii)). At the same time the land cat 726 transports the unloading container 722E to the upper conveyor line 764o and places it there (dash-dot-dash line (iii)).

In a fourth and final step of the work cycle leads the water trolley 728 is offset by approximately a stack width to pick up the next container from ship 718 (dash-dotted line (iv)) while the land cat 726 from the upper conveyor line 764o to the lower conveyor line 764u is lowered (dash-dot-dash line (iv)).

In the following, construction is shown with reference to FIGS. 12a to 12d and function of a third embodiment of a container loading crane be described by means of which also loading and unloading a container ship in double play is possible. Analogous in FIGS. 12a to 12d Provide parts with the same reference numerals as in the Figures 1 to 3, but increased by the number 800.

The container loading crane 810 differs from the container loading crane 10 according to Figure 1a in that both water cat 828 and land trolley 826 with two hoists 828b1 and 828b2 and 826b1 and 826b2 are equipped and further the transfer trolley 832 only has a receiving area 832s having. The distance of the container surface 838 des The receiving area 832s from the crane bridge 816 is dimensioned in such a way that the transfer cat loaded with a container Move 832 under a hoist carrying a container can, as shown in particular in Figure 12b is.

In Figure 12a, the conveyor 864 is only a rough schematic and the transfer devices and the transport device Not at all for the sake of clarity shown.

In the following, using the example of the 828 water cat Takeover of an 822B loading container from the transfer trolley 832 and the transfer of an unloading container 822E to the Transfercat 832 be described.

According to FIG. 12a, the transfer cat 832 has just moved from the Landkatze 826 took over the loading container 822B and is located on the water ride to water cat 828 (arrow W). The water cat 828 has the spreader 828c2 Unloading container 822E picked up by container ship 818 and raise it (arrow I ').

According to FIG. 12b, the water cat 828 has the unloading container 822E raised as much as possible so that the one with the Loading container 822B loaded transfer trolley 832 under the Drive hoist 828b2 through to under hoist 828b1 could. The spreader 828c1 is lowered to the loading container Take over 822B from the Tansferkatze.

After this has happened, the now empty transfer cat 832 moved under the hoist 828b2 according to FIG. 12c, so that the unloading container 822E is in the receiving area 832s can be turned off. This is where the transfer cat goes 832 according to FIG. 12d with the unloading container 822E on land (Arrow L) and the water cat 828 lowers the loading container 822B to the container ship (arrow I).

The handover or takeover of loading containers 822B and Unloading container 822E between transfer trolley 832 and land trolley 826 is done in a similar manner and is therefore are not described in detail.

In the following, structure and function will be explained with reference to FIG a further embodiment of a container loading crane are described, analog parts with the same reference numerals are provided, as in Figures 1 to 3, however increased by the number 1000. The container loading crane 1010 will only be described in so far as he differs from the container loading crane 10. Otherwise reference is made to its description.

The container loading crane 1010 differs from that Container loading crane 10 according to FIG. that instead of one along the crane bridge 1016 in the transfer direction W / L movable land cat (according to the Country cat 26 of the embodiment according to Figure 1a) a firm elevator 1026 arranged on the crane scaffold 1014 is provided. This has the advantage that the water cat 1028 is easy to use can pass the elevator 1026, for example by that of container ships older design existing hatch cover a bracket 1074 provided on the crane scaffold 1014 for this purpose.

The spreader 1026c of the elevator 1026 of the container loading crane 1010 is on its entire stroke between the crane bridge 1016 and the lower conveyor line 1064u from one Guided device 1072, so that even with strong Wind the shuttle 1026c and the one it grips Containers 1022 is prevented. The guide device 1072 is shown schematically in FIG. 13 with dash-dot-dotted lines Line indicated.

The container loading crane 1010 differs from that Container loading crane 10 also through the special training of the two conveyor lines 1064o and 1064u, which are next to the conveyor rail 1064o3 or 1064u3 also a return rail 1064o8 or 1064u8, which essentially runs parallel to the respective conveyor rail and the return of production platforms from one end of the production lines serve to the other end of the conveyor lines. For moving the conveyor platforms between the conveyor rails 1064o3 or 1064u3 and the associated return rail 1064o8 and 1064u8 are at both ends of the conveyor lines 1064o and 1064u conversion devices 1078 are provided.

The transfer devices 1078 comprise, according to FIGS. 14a and 14b a profiled section 1078a and an actuating device, e.g. two hydraulic cylinders 1078b. In the 14a shown extended position of the cylinder 1078b the profile carrier 1078a is aligned with the profile carrier 1064o5 of the conveyor track 1064o3, whereas in the in Figure 14b shown shortened position of the cylinder 1078b with the profile support 1064o9 of the return rail 1064o8 flees. Those assigned to the lower conveyor section 1064u Transfer devices 1078 are designed accordingly.

The formation of the conveyor lines explained above 1064o and 1064u allow the inclusion of multiple Production platforms in a production line. Thus a corresponding number of containers in the conveyor line to be included, in addition to the funding function at the same time the function of a buffer to compensate the delivery rates of the container loading crane 1010 and the Transport device 1068 can take over. According to FIG. 13 it is, for example, to a halt in the removal of the unloading containers (small arrow to the right) came as a result there are already four on the upper conveyor line 1064o Have unloaded containers. Because of the buffer function on the 1064o conveyor line, however, the container loading crane can 1010 despite this stalling without reduction of the Loading rate continues to load and unload container ship 1018.

After all, the container loading crane 1010 differs of the container loading crane 10 in that in the area of an additional lifting device 1076 provided with a hoist 1076b and a spreader 1076c is which loading containers take up directly from quay 1012 and, for example, put on the lower conveyor section 1064u can or unload container from the upper conveyor line 1064o on the quay 1012.

This additional lifting device 1076 enables special operation to be carried out, for example in such a way that containers delivered at short notice can be removed directly from a truck driven under the container loading crane 1010 and introduced into the loading cycle. The same applies to a special unloading operation. Furthermore, in the event of failure of the transport device 1068, for example, an emergency operation can be maintained, in which the containers can be delivered from the conveying lines to means of transport standing under the crane 1010 or can be applied to the conveying lines by these means of transport. This transport may, for example. Driverless transport, so-called AGV's (a utomatic g round v ehicle), semitrailers trains having a plurality of followers (so-called "trailer trains"), straddle carriers or the like. Be. Finally, if the transport level 1068o or 1068u responsible for the removal of the unloading containers is stagnated, it is possible to use the base level of quay 1012 as an extended buffer.

With all the embodiments of the invention described above and above using the example of a container loading crane Load loading cranes explained can load carriers, For example, container ships in time-saving double-game operation be loaded and unloaded. Because here according to the invention at the same time the game time advantages of one with several Trolleys equipped crane can be used results there is an overall significantly higher loading and unloading rate, which are shorter in the examples described above Mooring times of the ships with corresponding cost savings for the shipping companies.

15a to 15d are used in the following to set up and function of a further embodiment of a container loading crane to be discribed. In Figures 15a to 15d, analog parts are provided with the same reference symbols, as in Figures 1 to 3, but increased by Number 900.

The container loading crane 910 differs from the container loading crane 10 according to Figure 1b in that the transfer cat 932 only has a receiving area 932s and the conveyor 964 only one conveyor line 964s, which are roughly indicated in FIGS. 15a to 15d is. Accordingly, only a transfer device and a transport rail level is provided, which for the sake of clarity, however, are not shown.

The receiving area 932s is with an operating device 936s. With the container loading crane 910 are usually worked in single game mode, i.e. the container ship 918 is either loaded or unloaded, however, the equipment of the capture area brings 932s with the operating device 936s significant time advantages in Comparison to a conventional container loading crane, the only recording area not with an operating device is provided. This is illustrated below using the example of the Unloading of the container ship 918 in single-game operation closer are explained.

The starting point here is a situation as shown in FIG 15a is shown. The water cat 928 has the transfer cat 932 just handed over an unloading container 922E ' and lowers her spreader 928c without a container (arrow I), to accommodate the next unloading container 922E " Transfer cat 932 is meanwhile with the unloading container 922E 'on land (arrow L). The land cat 926 has the previous unloading container 922E on the conveyor line 964s turned off and is just about to be her spreader 926c without lifting the container (arrow II '). Meanwhile, the Unloading container 922E from the conveyor line 964s to the Transfer device (not shown) promoted (arrow Ts).

If the transfer cat 932 has reached the land cat 926, so it is locked with this. If the spreader 926c the land cat 926 finally in its highest position is located, the transfer cat 932 serves the land cat 926 the unloading container 922E '. According to FIG. 15b, it drives for this purpose the operating device 936s from the shore. On that the spreader 926c is lowered and attached to the unloading container 922E 'coupled.

According to FIG. 15b, the water cat 928 has its spreader 928c coupled to the next unloading container 922E " and lifts it according to FIG. 15c by means of its hoist 926b upwards (arrow I ').

The land cat 926 has the unloading container 922E 'from the Operating device 936s raised so that it is in the transfer trolley 932 could be confiscated. Now lowers it Country cat 926 according to FIG. 15c the unloading container 922E ' by means of its hoist 926b (arrow II). Meanwhile located the transfer trolley 932 can travel on water without a container (Arrow W). It is understood that the conveyor line 964s can be used for both loading and unloading.

The last described steps run with a conventional one Transfer trolley without control device as follows: Because of the time saved by the conveyor 964 for the transfer cat it reaches the land cat, before this land cat raised its spreader completely Has. So the transfer cat has to slow down and wait, until the spreader is fully raised. Then the transfer cat moves under the land cat, so that this can accommodate the unloading container. So that the country cat but then lower the unloading container to the quay the transfer cat must first move the space under the Have released land cat.

To move the transfer cat under the land cat, the large mass of transfer cat including the mass of the Unloading containers are accelerated and braked again and also to clear the space under the country cat first accelerated the mass of the transfer cat will. On the one hand, to accelerate this large mass much time required and secondly a lot of energy has to be used will.

In the container loading crane 910 according to the invention only the operating device for operating the unloading container 922E ' 936s to be extended and released the space under the land cat 926 is only needed to be drafted again. Hence, not the whole Mass of the transfer cat are accelerated, but only the far lower mass of the operating device. This on the one hand requires less time and on the other hand saves energy.

The transfer trolley 932 has the water trolley 928 according to the figure 15d reached, it is locked with this. Located the spreader 928c of the water cat 928 together with the Unloading container 922E "in its highest position, see above the operating device 936s extends on the water side. On that the spreader 928c places the unloading container 922E "on the Container contact area 938s and is uncoupled from this.

The land cat 926 meanwhile had the unloading container shortly before 922E 'parked on the conveyor line 964s and begins to raise her spreader 926c in the direction of arrow II '.

The inventive one also saves on the water-side container handover Container loading crane compared to the conventional one Container loading crane both time and energy a.

In addition, the equipment of the transfer trolley with an operating device control engineering advantages, because the control of the movements of the transfer trolley and the hoists unbundled from land or water cat, i.e. independently can be made from each other. As above described, must in the conventional container loading crane brake the transfer trolley in front of the respective lifting trolley, the wait for the spreader to fully raise and settle finally move on to just below the lifting trolley, i.e. the movement of the transfer trolley must be based on the movement of the hoist the lifting trolley is coordinated. Moved according to the invention the transfer cat immediately to its end position next to the lifting trolley. If the hoist is in its end position, i.e. reached its highest position, it is followed by a corresponding one Signal extended the operating device.

The respective end positions can be reached by actuation switch located on the lifting trolley by the Transfer trolley or the hoists are displayed. The control device is preferably designed such that it the required relative positioning in its maximum extended state to the hoist of the lifting trolley.

To load the container ship 918, the above described steps analogously in reverse order performed.

The time, energy and control advantage described above can also be used with a transfer cat with two on top of each other arranged load bearing areas can be achieved, if both load suspension areas with one control device are equipped, as is the case, for example, with the transfer cat 32 3a is the case.

It should also be noted that the use of the invention Load loading cranes not for loading and unloading Container ships are restricted. Rather, he can do anything can be used with advantage where large quantities of General cargo should be implemented in the shortest possible time.

It should also be noted that the number of conveyor lines as well as the transport rail levels as required can be chosen.

Although in the embodiments described above only the parking lane 68o1 or 68u1 of the transport device 68 was operated by the transfer device 66, it is in principle also possible through correspondingly longer training the transfer device also the acceleration or delay track or even the transport track of the transport device to operate directly.
