Description

Die Erfindung betrifft eine von einem Hebezeug heb- und senkbare Arbeitsbühne, insbesondere für Fassadenarbeiten an Gebäuden.The invention relates to a work platform that can be raised and lowered by a hoist, in particular for facade work on buildings.

Bislang ist es bekannt, eine korbartige Arbeitsbühne am freien Ende eines auf einem Flurförderfahrzeug angeordneten, höheneinstellbaren Kragarmes so selbsttätig einstellbar zu halten, daß beim Verstellen der Arbeitsbühne in der Höhe deren Boden stets waagerecht angeordnet ist.So far, it is known to keep a basket-like working platform at the free end of a height-adjustable cantilever arm arranged on an industrial truck so that it is always horizontally arranged when the working platform is adjusted in height.

Derartige Arbeitsbühnen haben aber nur eine relativ geringe Grundfläche, so daß bei Fassadenarbeiten, zum Beispiel zum Reinigen der gesamten Fassade, die Arbeitsbühne sehr oft in andere Positionen zur Fassade verstellt werden muß. Außerdem läßt eine derartige Arbeitsbühne den Einsatz von einer höchstens von zwei Personen zu, so daß derartige Arbeitsbühnen lediglich bei Reparaturarbeiten eingesetzt werden, ansonsten man aber herkömmliche, relativ aufwendig zu errichtende Fassadengerüste bevorzugt, um unter Einsatz mehrerer Personen unter anderem die Fassadenarbeiten schneller durchführen zu können.Such work platforms have only a relatively small footprint, so that with facades work, for example to clean the entire facade, the work platform very often has to be moved to other positions on the facade. In addition, such a work platform allows the use of a maximum of two people, so that such work platforms are used only for repair work, but otherwise conventional, relatively complex facade scaffolding is preferred in order to be able to perform facade work faster with the use of several people .

Aufgabe der Erfindung ist es nun, eine Arbeitsbühne der im Oberbegriff des Anspruches 1 angegebenen Art unter Beibehaltung des beim Stand der Technik bereits erreichten Vorteiles, nämlich, daß die Arbeitsbühne am Einsatzort mühelos und schnell in Arbeitsposition gebracht werden kann, darüber hinaus derart zu verbessern, daß mit dieser Fassadenarbeiten weit rationeller als mit bekannten, vorbeschriebenen Arbeitsbühnen ausführbar sind, wobei mit einfachen Mitteln und Maßnahmen auch eine hohe Lagesicherheit der jeweils vorgewählten Arbeitsbühnenposition erreichbar ist.The object of the invention is now to improve a work platform of the type specified in the preamble of claim 1 while maintaining the advantage already achieved in the prior art, namely that the work platform can be brought into the working position quickly and effortlessly, that with this facade work far more rationally than with known, previously described work platforms can be carried out, with simple means and measures also a high positional security of the respectively selected work platform position can be achieved.

Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß die Länge der Arbeitsbühne um ein Mehrfaches größer als deren Breite ist, daß ferner der Arbeitsbühne ein Lastaufnahmemittel mit einer Anhängeeinrichtung an ein Hebezeug zugeordnet ist, zudem die Arbeitsbühne am Lasthebemittel stabil hängbar angeschlossen ist und daß an beiden stirnseitigen Endteilen der Arbeitsbühne längenveränderbare Zugorgane angeordnet sind, an deren freien Endteilen Bodenanker angeordnet sind.The solution to this problem is characterized in that the length of the working platform by It is several times larger than its width that the work platform is also assigned a load suspension device with a hitch to a hoist, the work platform is also connected to the load lifting device in a stable, hanging manner, and that length-adjustable traction elements are arranged on both front end parts of the work platform, with ground anchors arranged on their free end parts are.

Hieraus resultiert eine Arbeitsbühne, die an einem nahezu beliebigen Kran angehängt werden kann, längsseits zu einer Fassade angeordnet sich über deren gesamte Breite erstrecken kann und mehreren Personen sowie Arbeitsmitteln viel Platz bietet und darüber hinaus auch in jeder vorgewählten Position pendelfrei gehalten wird.This results in a working platform that can be attached to almost any crane, arranged alongside a facade, can extend across its entire width and offers plenty of space for several people and work equipment, and is also held in any preselected position without a pendulum.

Eine im Sinne der Aufgabe förderliche Ausgestaltung kennzeichnet sich dadurch, daß der eine Endteil eines länglichen, insbesondere als Ösenteil ausgebildeten Lasthebemittels mindestens mannhoch über dem Boden der Arbeitsbühne an dieser und senkrecht über dem Arbeitsbühnenschwerpunkt befestigt ist, ferner das Lasthebemittel zwischen den Ösen oder dergleichen von einer Hülse umfaßt ist und daß an der Hülse mindestens zwei einander entgegengerichtete, zu den stirnseitigen Endteilen der Arbeitsbühne hinzielende und an diesen befestigte Stangen angeordnet sind, wobei vorzugsweise ferner die Hülse mit einem so großen Abstand über dem Boden der Arbeitsbühne angeordnet ist, der mindestens einem Drittel der Länge der Arbeitsbühne entspricht.A beneficial in the sense of the task is characterized in that the one end part of an elongated, in particular designed as an eyelet lifting means is attached at least man high above the floor of the work platform and perpendicular to the center of gravity of the work platform, furthermore the load lifting device between the eyelets or the like from one Sleeve is included and that on the sleeve at least two mutually opposite, facing towards the front end parts of the work platform and attached to them are arranged, wherein preferably the sleeve is further arranged with such a large distance above the floor of the work platform that at least a third corresponds to the length of the working platform.

Eine unter Umständen bevorzugte, störunanfälligere Variante ist hierzu dadurch gekennzeichnet, daß die Hülse an der Hebezeuganschlußeinrichtung des Lasthebemittels angehängt ist, und daß anstelle der mit der Hülse verbundenen und an den Endteilen der Arbeitsbühne befestigten Stangen Seile vorgesehen sind.A possibly preferred, less prone to failure is characterized in that the sleeve is attached to the hoist connection device of the lifting means and that instead of the rods connected to the sleeve and attached to the end parts of the work platform, ropes are provided.

Bevorzugterweise sind als Bodenanker Gewichte vorgesehen, wobei die Gewichtskraft der an jedem der Arbeitsbühnen-Endteile wirksamen Gewichte jeweils mindestens der maximalen Tragkraft der Arbeitsbühne entspricht. Unter Umständen ist es aber auch möglich, die Seile an bodenfesten Teilen, zum Beispiel an im Boden verankerte Pfähle oder auch an Bäumen festzubinden.Weights are preferably provided as floor anchors, the weight of the weights acting on each of the work platform end parts in each case corresponding at least to the maximum load capacity of the work platform. Under certain circumstances, however, it is also possible to tie the ropes to parts that are fixed to the ground, for example to piles anchored in the ground or to trees.

Eine vorteilhafte Weiterbildung der Arbeitsbühne besteht noch darin, daß an den Endteilen der Arbeitsbühne jeweils mehrere nebeneinander und über die Querseiten der Arbeitsbühne verteilt angeordnete Zugorgan-Anschlußeinrichtungen vorgesehen sind, so da-ß die vorzugsweise als Seile ausgebildeten Zugorgane unter Vorspannung jeweils an einem der Anschlußeinrichtungen freie Wahl festgelegt werden können, um die Arbeitsbühne bei Bedarf, zum Beispiel mehr oder weniger, verkanten zu können.An advantageous further development of the working platform is that at the end parts of the working platform several pulling element connecting devices arranged next to one another and distributed over the transverse sides of the working platform are provided, so that the pulling elements, preferably designed as ropes, are each free under tension on one of the connecting devices Choice can be specified in order to be able to tilt the work platform if necessary, for example more or less.

Hierzu kennzeichnet sich eine bevorzugte Ausgestaltung dadurch, daß die Zugorgananschlußeinrichtungen an der Arbeitsbühne quer zu deren Längserstreckung stufenlos verstell- und feststellbar angeordnet sind.For this purpose, a preferred embodiment is characterized in that the traction member connection devices are arranged on the work platform in a manner that is infinitely adjustable and lockable transversely to its longitudinal extension.

Zudem ist es vorteilhaft, an mindestens einer Längsseite der Arbeitsbühne seitlich abstrebende Abstandhalter anzuordnen, um die Arbeitsbühne zum Beispiel im ausreichenden Abstand von vorstehenden Fassadensimsen oder anderem sicher zu halten.In addition, it is advantageous to arrange spacers that laterally strut on at least one long side of the work platform in order to keep the work platform securely, for example, at a sufficient distance from projecting facade ledges or other things.

Dabei sollten die Abstandhalter bevorzugterweise an ihren freien Enden Stützrollen aufweisen, um beim Heben oder Senken der an einer Fassade seitlich abgestützten Arbeitsbühne Beschädigungen der Fassade durch die Arbeitsbühne weitgehend auszuschließen.The spacers should preferably have support rollers at their free ends in order to When lifting or lowering the work platform supported on the side of a facade, damage to the facade by the work platform is largely excluded.

Außerdem ist es hierbei vorteilhaft, wenn die Abstandhalter an der Arbeitsbühne zu deren Längserstreckung quer verstell- und einstellbar ausgebildet sind, und vorzugsweise zudem die Abstandhalter in Richtung zur Arbeitsbühne hin gegen Federkraft verstellbar gelagert sind.In addition, it is advantageous here if the spacers on the work platform are designed to be transversely adjustable and adjustable to their longitudinal extent, and preferably the spacers are mounted so as to be adjustable in the direction of the work platform against spring force.

Außerdem ist es vorteilhaft, wenn die Gewichte auf Flurförderfahrzeugen angeordnet, insbesondere an letzteren befestigt sind, um einerseits die Gewichte bequem transportieren zu können und um andererseits die Gewichtskraft der Gewichte durch die der Flurförderfahrzeuge zu erhöhen.In addition, it is advantageous if the weights are arranged on industrial trucks, in particular attached to the latter, in order to be able to transport the weights conveniently on the one hand and to increase the weight of the weights by that of the industrial trucks on the other hand.

Eine bevorzugte Ausführungsform der vorbeschriebenen Arbeitsbühne besteht darin, daß der Kranhaken an ein mit den Stangen fest verbindbares Kupplungsteil angehängt ist, ferner vom Kupplungsteil ein zur Längserstreckung der Arbeitsbühne rechtwinklig und nach oben gerichtete, formsteife und mit dem Kupplungsteil fest verbundene Hülse abstrebt, durch die das mit seinem freien Ende am Kupplungsteil befestigte Kranseil hindurchgeführt ist, und daß in der Gebrauchslage der Arbeitsbühne die Hülse samt Arbeitsbühne bis an die am freien Ende eines heb- und senkbaren Kranauslegers angeordnete Kranseil-Umlenkrolle angehoben ist.A preferred embodiment of the above-described working platform is that the crane hook is attached to a coupling part which can be fixedly connected to the rods, and furthermore from the coupling part a shape which is perpendicular and upward to the longitudinal extension of the working platform and is rigid with the coupling part Connected sleeve strives through which the free end of the crane cable attached to the coupling part is passed, and that in the position of use of the working platform, the sleeve including the working platform is raised up to the crane cable deflecting roller arranged at the free end of a lifting and lowering crane boom.

Hierzu sind vorteilhafte Ausgestaltungen in den Ansprüchen 15 bis 18 offenbart.For this purpose, advantageous embodiments are disclosed in claims 15 to 18.

Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher erläutert.Two embodiments of the invention are shown in the drawings and are explained in more detail below.

Es zeigt:

  • Fig. 1 eine Arbeitsbühne in der Vorderansicht,
  • Fig. 2 desgleichen in der Seitenansicht,
  • Fig. 3 eine bevorzugte Variante in der Vorderansicht.
It shows:
  • 1 is a front view of a working platform,
  • 2 likewise in a side view,
  • Fig. 3 shows a preferred variant in the front view.

Diese von einem nichtdargestellten Kran anheb- baren, biegesteifen Arbeitsbühnen 1 haben jeweils einen rechteckigen Boden 2 mit einer Länge von ca. 10 m und einer Breite von etwa 0,7 m.These rigid work platforms 1, which can be lifted by a crane (not shown), each have a rectangular floor 2 with a length of approximately 10 m and a width of approximately 0.7 m.

Am Boden 2 ist ein umlaufendes Geländer 3 befestigt. Mittig der Arbeitsbühne 1 ist ein etwa 6 m langes und etwa tunnelartiges sowie mindestens mannhohes Gerüst 4 vorgesehen, welches aus vier, paarweise oben miteinander überbrückten Stützen 5 und mindestens zwei mannhoch angeordneten Längsstreben 6 zusammengefügt ist. An den oberen Ecken dieses Gerüstes 4 ist jeweils ein Ösenseil 7 befestigt, deren freien Enden mittels eines Ringes 8 miteinander verbunden sind. Gemäß der Fig. 1 und 2 ist an den Ring 8 ein weiteres Ösenseil 9 angeschlossen, deren freier Endteil an einen Kranhaken 10 oder dergleichen angehängt werden kann.A peripheral railing 3 is attached to the floor 2. In the middle of the working platform 1 there is an approximately 6 m long and approximately tunnel-like and at least man-high scaffold 4, which is assembled from four supports 5 bridged in pairs at the top and at least two longitudinal struts 6 arranged as tall as a man. At the upper corners of this frame 4, an eyelet rope 7 is attached, the free ends of which are connected to one another by means of a ring 8. 1 and 2, a further eyelet rope 9 is connected to the ring 8, the free end part of which can be attached to a crane hook 10 or the like.

Das Ösenseil 9 ist von einer auf letzterem längsverstellbaren Hülse 11 umfaßt, von der zwei diametral entgegengerichtete, biegesteife Stangen 12 abstreben, deren anderen Endteile an den stirnseitigen Enden der Arbeitsbühne 1 befestigt sind. Die Stangen 12 haben einen lotrecht nach unten abgebogenen Schenkel, wobei die Abwinklung mindestens mannhoch angeordnet ist, damit die Stangen 12 die auf der Arbeitsbühne befindlichen Personen nicht behindern.The eyelet rope 9 is encompassed by a sleeve 11 which is longitudinally adjustable on the latter, from which two diametrically opposed, rigid rods 12 strive, the other end parts of which are attached to the front ends of the work platform 1. The rods 12 have a leg which is bent vertically downwards, the angled portion being arranged at least as high as a man, so that the rods 12 do not hinder the people on the work platform.

Der Ring 8 und die Hülse 11 sind senkrecht über der Arbeitsbühne und deren Schwerpunkt angeordnet. Zudem sind bei beiden Ausführungsformen an der Arbeitsbühne 1 an einer Längsseite mehrere über deren Länge verteilt angeordnete und quer abstrebende Abstandhalter 13 vorgesehen, die an ihren freien Enden um waagerechte und zu den Längsseiten der Arbeitsbühne parallel gerichtete Achsen frei drehbar gelagerte Stützrollen 14 tragen.The ring 8 and the sleeve 11 are arranged vertically above the work platform and its center of gravity. In addition, in both embodiments on the work platform 1 on a long side, a plurality of spacers 13, which are distributed over their length and arranged transversely, are provided, which at their free ends support support rollers 14 which are freely rotatable about horizontal axes parallel to the long sides of the work platform.

An allen Ecken des Bodens 2 sind noch je eine Anschlußeinrichtung 15 für je ein Zugorgan 16, vorzugsweise in Form von Seilen vorgesehen, an deren freien Enden Gewichte 17 befestigt sind. Die Summe der Gewichtskräfte der jeweils an einem Ende der Arbeitsbühne wirksam werdenden Gewichte 17 ist mindestens gleich der maximalen Tragkraft der Arbeitsbühne 1, so daß die Arbeitsbühne auch bei ungleichmäßiger Belastung immer waagerecht gehalten wird.At all corners of the floor 2 there are also one connection device 15 for each pulling member 16, preferably in the form of ropes, at the free ends of which weights 17 are fastened. The sum of the weight forces of the weights 17 which become effective at one end of the work platform is at least equal to the maximum load capacity of the work platform 1, so that the work platform is always kept horizontal, even when the load is uneven.

Die als Seile ausgebildeten Zugorgane können an der Arbeitsbühne und/oder den Gewichten lösbar angebunden sein, um deren wirksame Länge stets so einstellen zu können, daß die Seile in der Gebrauchslage der Arbeitsbühne immer unter Vorspannung angeordnet sind.The traction elements designed as ropes can be detachable on the working platform and / or the weights be connected so that their effective length can always be set so that the ropes are always under tension in the position of use of the work platform.

Gemäß Figur 3 ist der Kranhaken 10 an einem Kupplungsteil 18 angehängt, der mit den Stangen 12 fest verbunden ist. Hierzu sind an den oberen Enden der Stangen 12 je ein nach unten zielender Haken 19 angeformt, die jeweils in eine am Kupplungsteil 18 angeordnete oben offene Einstecköffnungen 20 form- und reibschlüssig eingreifen.According to Figure 3, the crane hook 10 is attached to a coupling part 18 which is fixed to the rods 12. For this purpose, a downwardly directed hook 19 is formed on the upper ends of the rods 12, each of which engages in a form-fitting and friction-locking manner in an insertion opening 20 which is arranged on the coupling part 18 and is open at the top.

Vom Kupplungsteil 18 strebt eine mit letzteren fest verbundene, formstabile Hülse 21 nach oben ab, die lotrecht über dem Schwerpunkt der Arbeitsbühne 1 angeordnet ist. Durch die Hülse 21 ist ein Kranseil 22 hindurchgeführt, dessen freier Endteil mit dem Kupplungsteil 18 verbunden ist.From the coupling part 18 a rigidly connected to the latter, dimensionally stable sleeve 21 strives upwards, which is arranged vertically above the center of gravity of the work platform 1. A crane cable 22 is passed through the sleeve 21, the free end part of which is connected to the coupling part 18.

In der Gebrauchsstellung der Arbeitsbühne soll mit dem Kranseil 22 die Hülse 21 mit ihrem oberen Endteil möglichst nahe bis an eine Seilumlenkrolle 23 angehoben werden, die am freien Ende eines ansich bekannten heb- und senkbaren Kranauslegers gelagert ist.In the position of use of the working platform, the sleeve 21 is to be raised with its upper end part as close as possible to a rope deflection roller 23, which is at the free end, with the crane rope 22 End of a known lifting and lowering crane boom is mounted.

An den Lasthaken 10 ist in Figur 3 der Ring 8 angehängt, an welchen wie beim Gegenstand der Fig. 1 + 2 die als Ösenseile ausgebildeten Lasthebemittel 7 angehängt sind.In FIG. 3, the ring 8 is attached to the load hook 10, to which the load lifting means 7 designed as eyelet ropes are attached, as in the case of FIGS. 1 + 2.

Gemäß Figur 3 sind an den Ring 8 noch zwei weitere, vorzugsweise als Ösenseile ausgebildete Lasthebemittel 24 angehängt, deren unteren Endteile jeweils an einer der beiden Längsstreben 6 mittig dieser so befestigt sind, daß beim Anheben der Arbeitsbühne alle Lasthebemittel 7 und 24 gespannt sind.According to FIG. 3, two further load lifting means 24, preferably designed as eyelet ropes, are attached to the ring 8, the lower end parts of which are each fastened centrally to one of the two longitudinal struts 6 such that all load lifting means 7 and 24 are tensioned when the working platform is raised.

Der Kupplungsteil 18 ist bevorzugter Weise als Haken-Belastungsgewicht ausgebildet.The coupling part 18 is preferably designed as a hook loading weight.
