^*>- or set-down device for transportable large containers, e.g. containers, sh ters, cabins or the like

The innovation relates to a lifting or lowering device for transportable large containers, e.g. containers, shelters, cabins or the like, with connecting beams arranged vertically at the corners of the large container, to which booms are pivotably attached via vertically spaced bearing bushes, which carry rack and pinion winches at their free ends.

A lifting or setting device of the above type is known from German patent specification 1 169 374. In this design, the booms are fixed, i.e. permanently connected to the bearing bushes on the connecting beams, and the rack and pinion winches or their housings are also fixed, although rotatably mounted on the free ends of the booms. The rack and pinion winches and their booms therefore form, together with the connecting beams, a part of the respective large container. If, for example, after loading

If the rack and pinion winches are not used for lifting the large container onto a transport vehicle, they can be moved in the raised or raised state by pivoting the booms around the connecting beams against the front walls of the large container. The booms assume a position that is approximately parallel to the front walls of the large container, while the rack and pinion winches or their winch housings protrude outwards at an acute angle. The space required by the rack and pinion winches, including their booms, is considerable when pivoted into their rest positions, and for many cases in which there is little space available between one end of the large container and the rear wall of the driver's cab of the transport vehicle in question, this known lifting or lowering device is therefore not suitable. The relatively large swivel radius of the rack and pinion winches is also a problem when several large containers are to be loaded in a row rather than one behind the other, as the space required by the rack and pinion winches and their booms is often not available. This is particularly critical when loading large containers into transport aircraft.

The innovation is based on the task of eliminating the above deficiencies and creating a lifting or lowering device for transportable large containers, which can be loaded even in confined spaces - partially dismantled depending on requirements, i.e. space availability - in the area surrounding the large containers.

According to the innovation, the above task is solved by connecting each bearing bush with a boom and/or each rack winch via perforated connecting plates by means of pins.

is detachably connected to the free end of a boom and the bearing bushes are rigidly connected to one another by a part that can be rotated around the connecting beam. If the rack and pinion winches are no longer required after the loading process, they can be easily removed from the connecting beams together with their booms by loosening the locking pins. All that remains on the large container in question is the connecting beams with the bearing bushes and connecting parts. However, these parts only take up relatively little space, so that the problems explained above, which are relevant to the current state of technology, can no longer occur. In some cases, where there is a little more space available opposite the front ends of the large container, it may be sufficient to simply remove the rack and pinion winches from the booms by loosening the locking pins and then swivel or fold the booms against the front ends of the large container.

Advantageous embodiments of the innovation emerge from subclaims 2-4.

The innovation is then explained using drawings of an example. They show:

The large container 10 to be lifted or lowered has a rectangular plan and has vertically spaced corner fittings 11 at its four corners, to each of which a connecting beam 12 is attached. The connecting beams ]? in the example ^{design never} consist of round tubes _;

The lifting or lowering device for the large container 10 has four identical rack winches, which can be detachably connected to the connecting rods 12 via booms 14. The rack winches 13 each comprise a rack 16 attached to a support tube 15 or formed as one piece thereon, which works together with the pinion of a wall gear, which is installed in the gear housing 17. A guide housing 18 for the rack 16 and its support tube 15 is firmly connected to the gear housing 17 of the rack winch 13. The rack winches 13 are preferably connected in pairs by drive shafts (not shown), so that only two rack winches 13 need to be operated, e.g. via hand cranks, in order to

to activate the complete lifting or lowering device. Individual operation of the rack winches 13 with four hand cranks is also possible.

Each boom 14 consists of a welded

can be aligned. From this it can be seen that the complete rack and pinion winch 13 can be detachably connected to the boom 14 via the connecting lugs 21 and plug pins 22. The connecting part 19 of the boom is introduced into the space between the connecting lugs 21 until the connecting ^lugs 21 are laterally aligned.

are aligned so that the pins 22 can be inserted. To separate the rack and pinion jack 13 from the

; boom 14 you only need the pins 22

to remove.

Bearing bushes 23 are mounted on each connecting beam 12 so that they can rotate and are rigidly connected to one another and spaced apart vertically by a part 28, e.g. a rod. Two perforated connecting lugs 24 are attached to the end of the connecting part 20 of each boom 14, through which plug pins 22 can be passed. If the connecting lugs 24 on the connecting part 20 of the boom 14 are placed on the rod-shaped part 28 on the bearing bushes 23, which is provided with corresponding holes,

they are fixed to it by means of the plug pins 22. The lower bearing bush 23 of each arrangement is supported on a ring 25 which is fastened to each connecting beam 12. Furthermore, for example, the lower bearing bush 21 of each winch arrangement can be fixed to the

Rest position or parking position of the boom 14 (Fig.3) can be locked. For this purpose, each lower bearing bush 23 is provided with correspondingly laterally aligned bores, as is each boom spar

If it turns out during loading of the large container 10 that there is little space between one end face 26 and the opposite wall 27 of the driver's cab of the transport vehicle in question, the two booms 14 including their rack winches are removed from the connecting beams by pulling out the plug pins 22.

12 separated and stored separately. In this case, a swivel radius R 1 is achieved for the remaining parts on the connecting bars 12 (Fig.3). If, however, more ^space is available, it may be sufficient to only use the rack winders;

13 from the booms 14 and to swivel the booms 14 into the parking position shown in Fig. 3. In this position they can be locked again, as already mentioned, by means of locking pins 22 which are passed through corresponding holes in the lower bearing bushes 23 and the two connecting beams 12. In this case, a swivel radius R 2 is required.
