Definitions
- the invention relates to a lifting platform with a vertically supported platform that can be moved on at least one mast that can be assembled from stackable mast elements and a lifting device arranged above the platform, a lifting crane with a crane girder that extends essentially over the entire length of the platform and along a running track of the crane girder back and forth trolley is provided.
- Lifting platforms which are available in one and two mast versions, have already proven themselves as mobile climbing scaffolds and offer considerable advantages over rigid scaffolding, such as work opportunities with optimal access height, construction unit made of scaffolding and elevator, large work surface on the platforms, maximum safety and the like. Like, with himself.
- EP-A-0 106 506 it is also known to equip the platform of these lifting platforms with a jib crane, in order to have a hoist available at higher platform positions for hoisting building material, should the use of the platform itself be inappropriate as an elevator his.
- the use of these jib cranes is relatively small, since on the one hand they only have a vertical conveying function like the platform itself and on the other hand they impair the load-bearing capacity of the platform.
- DE-A-3 843 367 already shows an aerial work platform which has a longitudinally conveying conveyor belt below the platform and is equipped with an electric winch at the side end, but these conveying devices are only used for material removal and there is again an additional platform load.
- DE-U-89 12 853 also discloses an aerial work platform in which a work platform which is vertically adjustable along the supports of a chassis has a traveling crane with a crane girder and trolley extending over the platform length.
- this overhead crane has a horizontal conveying area, it is limited by the guides of the platform that receive the stencils between the crane girders, and because of the longitudinally centered running path along the crane girder, it needs a rotating boom for the trolley.
- Such a platform is only suitable for use with small movable working platforms, but not for lifting platforms with masts that can be assembled to great heights.
- the invention is therefore based on the object to eliminate these deficiencies and to create a lifting platform of the type described, which with comparatively little additional effort brings a significant improvement in working conditions on the platform and is characterized by a considerable expansion of their work area.
- the invention solves this problem in that the crane girder is laid in the area of the inner longitudinal edge of the platform facing the building and the track forms arc sections leading around the masts on the outer side facing away from the building, preferably the arc sections via switches on the straight sections extended on both sides towards the masts are connected.
- This overhead crane covers the entire platform with its conveying area regardless of the number and arrangement of the masts and enables the desired cross transport of building materials and tools on the platform, so that practically all construction and assembly work on the platform is made considerably easier.
- This overhead crane which is equipped with appropriate lifting and moving devices such as vacuum lifters or the like, is particularly suitable for the simple and efficient moving of facade panels or the like.
- the conveyor area of the overhead crane is as close as possible to the facade or the like to be processed and there is a favorable load on the lift. If there are also straight sections of the track extended on the mast side in addition to the curved sections, the crane trolley can not only be moved lengthways along the platform around the masts, but it can also be brought up to the masts so that they can also be used in the vicinity of the masts.
- the curved sections protrude in the apex area beyond the outer longitudinal edge of the platform facing away from the building, so that the trolley positioned in these areas lower their lifting means past the platform to the floor can and if necessary the overhead crane for vertical conveying of building material, tools and. The like. Can be used.
- the overhead crane can be set up directly on the platform if the crane girder is supported on the platform, which makes the crane immediately ready for use with the platform, but in this case the load capacity is limited by the impairment of the platform payload. It is therefore particularly favorable if the crane girder is supported on the top or top mast elements of the masts, since this arrangement of the overhead crane enables the crane loads to be directly integrated into the lift masts and the platform platform maintains its full payload.
- the masts are first erected using the platform and then mounted on top of the masts of the crane girder, which is preferably composed of elements.
- the crane girder connecting the masts which can of course also connect masts of two lifting platforms placed next to each other, brings additional stiffening of the supporting frame for the lifting platform provided by the masts.
- a very useful construction results from the fact that the crane girder has cross-adjustable cantilever arms for taking up the running track, because the cross-adjustability of these cantilever arms means that the conveying area of the overhead crane can be adapted to the respective platform width and position.
- a lifting platform 1 consists of two masts 2 built on a base frame (not shown) and one of these masts 2, the platform 3 being movable along the height.
- the masts 2 can be composed of individual mast elements 2a and the platform 3 can also be composed of individual platform elements 3a , so that there is a climbing frame that can be adapted to the particular circumstances, the platform 3 being supported on the masts 2 by its own sledge-shaped drive elements 3b connected to the masts 2 and being movable by means of a rack and pinion drive (not shown).
- the lifting platform 1 is assigned a traveling crane 4 which, according to the exemplary embodiment according to FIG. 1, has a stay 5 on the platform 3 itself is supported.
- the overhead crane 4 comprises a crane girder 6 which extends over the entire platform length and a trolley 7 which can be moved along the runway 6a of the crane girder 6, as a result of which horizontal conveyance of the building materials, for example the heavy facade cladding panels, is possible in the platform area.
- the crane girder 6 runs in the area of the inner longitudinal edge 8 of the platform 3 in order to bring the conveying area of the overhead crane 4 as far as possible in line with the facade-side working area, so that the crane girder 6 with its track 6a for bypassing the masts 2 forms arch sections 9 which are about Points 10 are connected to the straight sections 11 extended towards the masts 2.
- the trolley 7 can drive around the masts and be moved along the entire length of the platform, but the trolley 7 can be moved in a straight line towards the masts 2 after the switch 10 has been moved, so that it can also be used in the vicinity of the masts to be able to.
- the overhead crane 4 consists of a crane girder 12 designed as a truss girder, which, like the platform 3, can be composed of individual girder elements 12a.
- This crane girder 12 is supported on the uppermost mast elements 2b of the masts 2 and it has cross-adjustable cantilever arms 13 in the lower chord area for receiving the track 14, so that the position of the track 14 can be adapted to the width of the platform 3.
- the track 14 is guided through arc sections 15 around the masts 2 and the straight sections 17 connected via switches 16 continue up to the masts 2, so that the trolley 7 in turn can be guided around the masts or up to the masts can.

Abstract
Description
Die Erfindung bezieht sich auf eine Hebebühne mit einer an wenigstens einem aus übereinandersetzbaren Mastelementen zusammenbaubaren Mast der Höhe nach verfahrbar abgestützten Plattform und einem oberhalb der Plattform angeordneten Hebezeug, wobei als Hebezeug ein Laufkran mit sich im wesentlichen über die ganze Plattformlänge erstreckendem Kranträger und entlang einer Laufbahn des Kranträgers hin- und herfahrbarer Laufkatze vorgesehen ist.The invention relates to a lifting platform with a vertically supported platform that can be moved on at least one mast that can be assembled from stackable mast elements and a lifting device arranged above the platform, a lifting crane with a crane girder that extends essentially over the entire length of the platform and along a running track of the crane girder back and forth trolley is provided.
Hebebühnen, die es in Ein- und Zweimastausführungen gibt, haben sich als mobile Klettergerüste bereits bestens bewährt und bringen gegenüber starren Baugerüsten beträchtliche Vorteile, wie Arbeitsmöglichkeit in optimaler Zugriffshöhe, Konstruktionseinheit aus Gerüst und Aufzug, große Arbeitsfläche auf den Plattformen, höchste Sicherheit u. dgl., mit sich. Gemäß der EP-A- 0 106 506 ist es auch schon bekannt, die Plattform dieser Hebebühnen mit einem Auslegerkran zu bestücken, um bei höheren Plattformpositionen hilfsweise ein Hebezeug zum Hochfördern von Baumaterial zur Verfügung zu haben, sollte der Einsatz der Plattform selbst als Aufzug unzweckmäßig sein. Allerdings ist der Nutzen dieser Auslegerkräne relativ gering, da sie einerseits wie die Plattform selbst nur eine vertikale Förderfunktion besitzen und anderseits die Tragfähigkeit der Plattform beeinträchtigen. Wie aus der EP-A-0 082 290 hervorgeht, wurde auch schon vorgeschlagen, auf einem der Tragmaste einen Auslegerkran als Hilfskran aufzusetzen, wodurch die volle Tragfähigkeit der Plattform erhalten bleibt, aber wegen der Bindung des Hilfskranes an einen Tragmast wiederum nur ein recht beschränkter, im wesentlichen vertikaler Förderbereich zustande kommt. Zur Unterstützung der Montagearbeiten auf der Plattform, insbesondere beim Versetzen meist schwerer Fassadenplatten od. dgl., lassen sich diese bekannten Auslegerkräne praktisch nicht heranziehen und horizontale Materialförderungen bleiben einem mühsamen händischen Zugreifen vorbehalten.Lifting platforms, which are available in one and two mast versions, have already proven themselves as mobile climbing scaffolds and offer considerable advantages over rigid scaffolding, such as work opportunities with optimal access height, construction unit made of scaffolding and elevator, large work surface on the platforms, maximum safety and the like. Like, with himself. According to EP-A-0 106 506, it is also known to equip the platform of these lifting platforms with a jib crane, in order to have a hoist available at higher platform positions for hoisting building material, should the use of the platform itself be inappropriate as an elevator his. However, the use of these jib cranes is relatively small, since on the one hand they only have a vertical conveying function like the platform itself and on the other hand they impair the load-bearing capacity of the platform. As can be seen from EP-A-0 082 290, it has also been proposed to use a jib crane on one of the support masts To set up the auxiliary crane, whereby the full load-bearing capacity of the platform is maintained, but due to the connection of the auxiliary crane to a mast, only a very limited, essentially vertical conveying area is achieved. To support the assembly work on the platform, especially when moving mostly heavy facade panels or the like, these known jib cranes can practically not be used and horizontal material conveyors are reserved for laborious manual access.
Die DE-A-3 843 367 zeigt zwar bereits eine Hubarbeitsbühne, die unterhalb der Plattform ein längs förderndes Förderband aufweist und am Seitenende mit einr Elektrowinde ausgestattet ist, doch dienen diese Fördereinrichtungen nur zum Materialabtransport und es kommt erneut zu einer zusätzlichen Plattformbelastung.DE-A-3 843 367 already shows an aerial work platform which has a longitudinally conveying conveyor belt below the platform and is equipped with an electric winch at the side end, but these conveying devices are only used for material removal and there is again an additional platform load.
Aus der DE-U-89 12 853 ist weiters eine Hubarbeitsbühne bekannt, bei der eine entlang von Stehern eines Fahrgestells höhenverstellbar geführte Arbeitsplattform einen Laufkran mit sich über die Plattformlänge erstreckendem Kranträger und Laufkatze aufweist. Dieser Laufkran besitzt zwar einen horizontalen Förderbereich, der aber durch die zwischen sich den Kranträger aufnehmenden, die Stener umfassenden Führungen der Plattform begrenzt ist, und er braucht wegen der längsmittigen Laufbahn entlang dem Kranträger einen Drehausleger für die Laufkatze. Eine solche Plattform eignet sich nur zum Einsatz bei kleinen verfahrbaren Arbeitsbühnen, nicht aber für Hebebühnen mit zu großen Höhen zusammenbaubaren Masten.DE-U-89 12 853 also discloses an aerial work platform in which a work platform which is vertically adjustable along the supports of a chassis has a traveling crane with a crane girder and trolley extending over the platform length. Although this overhead crane has a horizontal conveying area, it is limited by the guides of the platform that receive the stencils between the crane girders, and because of the longitudinally centered running path along the crane girder, it needs a rotating boom for the trolley. Such a platform is only suitable for use with small movable working platforms, but not for lifting platforms with masts that can be assembled to great heights.
Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Hebebühne der eingangs geschilderten Art zu schaffen, die mit vergleichsweise geringem Mehraufwand eine wesentliche Verbesserung der Arbeitsbedingungen auf der Plattform mit sich bringt und sich durch eine beträchtliche Erweiterung ihres Arbeitsbereiches auszeichnet.The invention is therefore based on the object to eliminate these deficiencies and to create a lifting platform of the type described, which with comparatively little additional effort brings a significant improvement in working conditions on the platform and is characterized by a considerable expansion of their work area.
Die Erfindung löst diese Aufgabe dadurch, daß der Kranträger im Bereich des gebäudezugewandten inneren Längsrandes der Plattform verlegt ist und die Laufbahn an der gebäudeabgewandten äußeren Seite um die Maste herumführende Bogenabschnitte bildet, wobei vorzugsweise die Bogenabschnitte über Weichen an den beidseits zu den Masten hin verlängerten Geradeabschnitten angeschlossen sind. Dieser Laufkran erfaßt mit seinem Förderbereich unabhängig von der Zahl und Anordnung der Masten die gesamte Plattform und ermöglicht den angestrebten Quertransport von Baumaterial und Werkzeugen auf der Plattform, so daß praktisch alle Bau- und Montagearbeiten auf der Plattform wesentlich erleichtert werden. Vor allem zum einfachen und rationellen Versetzen von Fassadenplatten od. dgl. eignet sich dieser Laufkran, der dazu mit entsprechenden Hebe- und Versetzgeräten, wie Vakuumheber od. dgl., ausgestattet wird. Durch die innenliegende Laufbahn ist der Förderbereich des Laufkranes möglichst nahe an die zu bearbeitende Fassade od. dgl. herangerückt und es kommt zu einer günstigen Belastung der Hebebühne. Gibt es zusätzlich zu den Bogenabschnitten auch mastseitig verlängerte Geradeabschnitte der Laufbahn, kann die Kranlaufkatze nicht nur entlang der Plattform um die Maste herum längsverfahren werden, sondern sie läßt sich auch bis an die Maste heranbringen, um auch im Nahbereich der Maste einsetzbar zu sein.The invention solves this problem in that the crane girder is laid in the area of the inner longitudinal edge of the platform facing the building and the track forms arc sections leading around the masts on the outer side facing away from the building, preferably the arc sections via switches on the straight sections extended on both sides towards the masts are connected. This overhead crane covers the entire platform with its conveying area regardless of the number and arrangement of the masts and enables the desired cross transport of building materials and tools on the platform, so that practically all construction and assembly work on the platform is made considerably easier. This overhead crane, which is equipped with appropriate lifting and moving devices such as vacuum lifters or the like, is particularly suitable for the simple and efficient moving of facade panels or the like. Due to the internal track, the conveyor area of the overhead crane is as close as possible to the facade or the like to be processed and there is a favorable load on the lift. If there are also straight sections of the track extended on the mast side in addition to the curved sections, the crane trolley can not only be moved lengthways along the platform around the masts, but it can also be brought up to the masts so that they can also be used in the vicinity of the masts.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ragen die Bogenabschnitte im Scheitelbereich über den gebäudeabgewandten äußeren Längsrand der Plattform hinaus, so daß die in diesen Bereichen positionierte Laufkatze ihre Lasthebemittel an der Plattform vorbei bis zum Boden absenken kann und bedarfsweise der Laufkran auch zur Vertikalförderung von Baumaterial, Werkzeug u. dgl. einsetzbar ist.According to an advantageous embodiment of the invention, the curved sections protrude in the apex area beyond the outer longitudinal edge of the platform facing away from the building, so that the trolley positioned in these areas lower their lifting means past the platform to the floor can and if necessary the overhead crane for vertical conveying of building material, tools and. The like. Can be used.
Der Laufkran läßt sich, wenn der Kranträger über Steher an der Plattform abgestütz ist, direkt auf der Plattform aufbauen, was zwar den Kran sofort mit der Plattform einsatzbereit macht, doch ist in diesem Fall die Tragkraft durch die Beeinträchtigung der Bühnennutzlast beschränkt. Besonders günstig ist es daher, wenn der Kranträger an den oberen bzw. obersten Mastelementen der Maste abgestützt ist, da diese Anordnung des Laufkranes eine unmittelbare Einbindung der Kranlasten in die Hebebühnenmaste ermöglicht und die Bühnenplattform ihre volle Nutzlast beibehält. Zum Aufbau einer sochen Hebebühne werden zuerst die Maste mit Hilfe der Plattform errichtet und dann oben auf die Maste der Kranträger, der vorzugsweise aus Elementen zusammengesetzt ist, montiert. Der die Maste verbindende Kranträger, der selbstverständlich auch Maste zweier nebeneinander aufgestellter Hebebühnen verbinden kann, bringt dabei eine zusätzliche Versteifung des durch die Maste gegebenen Traggerüstes für die Hebebühne mit sich.The overhead crane can be set up directly on the platform if the crane girder is supported on the platform, which makes the crane immediately ready for use with the platform, but in this case the load capacity is limited by the impairment of the platform payload. It is therefore particularly favorable if the crane girder is supported on the top or top mast elements of the masts, since this arrangement of the overhead crane enables the crane loads to be directly integrated into the lift masts and the platform platform maintains its full payload. To set up such a lifting platform, the masts are first erected using the platform and then mounted on top of the masts of the crane girder, which is preferably composed of elements. The crane girder connecting the masts, which can of course also connect masts of two lifting platforms placed next to each other, brings additional stiffening of the supporting frame for the lifting platform provided by the masts.
Eine sehr zweckmäßige Konstruktion ergibt sich dadurch, daß der Kranträger querverstellbare Auslegerarme zur Aufnahme der Laufbahn aufweist, da durch die Querverstellbarkeit dieser Auslegerarme der Förderbereich des Laufkranes an die jeweilige Plattformbreite und -lage angepaßt werden kann.A very useful construction results from the fact that the crane girder has cross-adjustable cantilever arms for taking up the running track, because the cross-adjustability of these cantilever arms means that the conveying area of the overhead crane can be adapted to the respective platform width and position.

- 1 and 2
- two embodiments of a lifting platform according to the invention each in the diagram and
- Fig. 3
- a detail of the lift of Fig. 2 on a larger scale.
Eine Hebebühne 1 besteht aus zwei auf einem nicht weiter dargestellten Basisgestell aufgebauten Masten 2 und einer diesen Masten 2 entlang der Höhe nach verfahrbaren Plattform 3. Die Maste 2 lassen sich aus einzelnen Mastelementen 2a zusammensetzen und auch die Plattform 3 kann aus einzelnen Plattformelementen 3a zusammengesetzt werden, so daß sich ein an die jeweiligen Gegebenheiten baukastenmäßig anpaßbares Klettergerüst ergibt, wobei die Plattform 3 über eigene, an den Masten 2 angeschlossene schlittenförmige Antriebselemente 3b an den Masten 2 abgestützt und mittels eines nicht weiter dargestellten Zahnstangen-Ritzelantriebes verfahrbar ist.A
Um die Bau- und Montagearbeiten auf der Plattform 3, insbesondere die Verlegearbeiten von Fassadenplatten u.dgl., zu vereinfachen und zu erleichtern, ist der Hebebühne 1 ein Laufkran 4 zugeordnet, der gemäß dem Ausführungsbeispiel nach Fig. 1 über Steher 5 auf der Plattform 3 selbst abgestützt ist. Der Laufkran 4 umfaßt einen sich über die ganze Plattformlänge erstreckenden Kranträger 6 und eine der Laufbahn 6a des Kranträgers 6 entlang verfahrbare Laufkatze 7, wodurch im Plattformbereich eine Horizontalförderung der Baumaterialien, beispielsweise der schweren Fassadenverkleidungsplatten, möglich ist. Der Kranträger 6 verläuft im Bereich des inneren Längsrandes 8 der Plattform 3, um den Förderbereich des Laufkranes 4 möglichst mit dem fassadenseitigen Arbeitsbereich in Übereinstimmung zu bringen, so daß der Kranträger 6 mit seiner Laufbahn 6a zur Umgehung der Maste 2 Bogenabschnitte 9 bildet, die über Weichen 10 an den zu den Masten 2 hin verlängerten Geradeabschnitten 11 angeschlossen sind. Dadurch kann die Laufkatze 7 die Maste umfahren und der ganzen Plattformlänge entlang verschoben werden, die Laufkatze 7 kann aber nach Umstellung der Weichen 10 geradlinig zu den Masten 2 hin verfahren werden, um auch im Nahbereich der Maste eingesetzt werden zu können.In order to simplify and facilitate the construction and assembly work on the
Gemäß dem Ausführungsbeispiel nach Fig. 2 besteht der Laufkran 4 aus einem als Fachwerkträger ausgebildeten Kranträger 12, der sich ähnlich wie die Plattform 3 aus einzelnen Trägerelementen 12a zusamensetzen läßt. Dieser Kranträger 12 ist an den obersten Mastelementen 2b der Maste 2 abgestützt und er weist im Untergurtbereich querverstellbare Auslegerarme 13 zur Aufnahme der Laufbahn 14 auf, so daß sich die Lage der Laufbahn 14 an die Breite der Plattform 3 anpassen läßt. Auch hier ist die Laufbahn 14 durch Bogenabschnitte 15 um die Maste 2 herumgeführt und die über Weichen 16 angeschlossenen Geradeabschnitte 17 setzen sich bis zu den Masten 2 hin fort, so daß die Laufkatze 7 wiederum wahlweise um die Maste herum oder bis an die Maste herangeführt werden kann. Ragen die Scheitelstücke 15a der Bogenabschnitte 15 über den äußeren Längsrand 18 der Plattform 3 hinaus, kann die Laufkatze 7, wenn sie im Bereich dieser Scheitelstücke 15 a positioniert ist, mit ihrem Lastaufnahmemittel an der Plattform 3 vorbei den Boden erreichen und zu vertikalen Förderzwecken herangezogen werden.According to the exemplary embodiment according to FIG. 2, the
