Description

Die Erfindung betrifft eine Vorrichtung zum Anhängen von Abfallbehältern o. dgl., die mit einer mit der Behälterwanne oder -glocke verbundenen Lastöse und einer Zugöse versehen sind, die an einem Zugmittel zum Öffnen von Bodenklappen und/oder Seitenteilen des Behälters vorgesehen ist, an ein Hebezeug, vorzugsweise an einen Ausleger eines Ladekrans, mit Last- und Zughaken für jede der Ösen.The invention relates to a device for attaching waste containers or the like, which are provided with a load eye connected to the container trough or bell and a pulling eye which is provided on a pulling means for opening bottom flaps and / or side parts of the container Hoist, preferably on a boom of a loading crane, with load and pull hooks for each of the eyes.

Im Rahmen des steigenden Umweltbewußtseins ist in der Bevölkerung auch das Verständnis für das sogenannte Recycling von Abfallstoffen gestiegen. Um dieses Recycling in wirtschaftlicher Weise zu ermöglichen, werden an zentralen Sammelstellen Batterien von Abfallbehältern aufgestellt, die üblicherweise mit einer geschlossenen Behälterglocke mit Bodenklappen versehen sind, die Einwurföffnungen aufweisen, die der Art der zu sammelnden Abfälle angepaßt sind. So sind die Abfallbehälter meist im oberen Bereich ihres glockenförmigen Gehäuses mit runden Einwurföffnungen für Flaschen und Glasbehälter, mit schlitzförmigen Öffnungen zum Einwerfen für Altpapier und mit runden oder quadratischen Öffnungen zum Einwerfen von Metalldosen versehen.In the context of increasing environmental awareness, the understanding of the so-called recycling of waste materials has also increased among the population. In order to enable this recycling in an economical manner, batteries from waste containers are set up at central collection points, which are usually provided with a closed container bell with bottom flaps which have insertion openings which are adapted to the type of waste to be collected. The waste containers are usually provided in the upper area of their bell-shaped housing with round insertion openings for bottles and glass containers, with slot-shaped openings for inserting waste paper and with round or square openings for inserting metal cans.

Um die Recycling-Behälter gegen unbefugtes Öffnen zu schützen, weisen diese üblicherweise Bodenklappen oder mit Bodenteilen versehene klappbare Seitenteile auf, die sich scherenartig öffnen und schließen können. Dabei sind die Klappen mit Zugseilen oder Gestängen versehen, so daß sie durch Anheben oder Absenken von Zugösen geöffnet werden können. Neben diesen Zugösen sind die Behälter noch mit Tragösen versehen, die dem Anheben, Verschwenken und/oder Versetzen dienen. Die Zug- oder Tragösen sind nebeneinander angeordnet, so daß die dem Heben und Öffnen dienenden Last- und Zughaken des Hebezeuges etwa gleichzeitig in die Ösen eingehakt werden müssen.In order to protect the recycling containers against unauthorized opening, they usually have bottom flaps or hinged side parts provided with bottom parts, which can open and close like scissors. The flaps are provided with pull ropes or rods so that they can be opened by lifting or lowering the pull eyes. In addition to these towing eyes, the containers are also provided with lifting eyes, which are used for lifting, pivoting and / or moving. The pulling or lifting eyes are arranged next to each other so that the lifting and pulling hooks of the hoist used for lifting and opening have to be hooked into the eyelets at about the same time.

Ein besonderes Problem der die Last- und Zughaken aufweisenden Einrichtung besteht darin, daß der Zughaken selbständig relativ zu dem Lasthaken anhebbar und absenkbar sein muß, um das Öffnen und Schließen des abfallbehälters zu bewirken.A particular problem of the device comprising the load and pull hooks is that the pull hook must be able to be raised and lowered independently in relation to the load hook in order to bring about the opening and closing of the waste container.

Zum Heben und Entleeren von Abfallbehältern mit Trag- und Zugöse ist est bekannt, einen mit einem Kranhaken versehenen Ausleger eines Ladekrans zu verwenden, der parallel zu dem den Lasthaken tragenden Seil mit einem über eine Umlenkrolle laufenden Seil versehen ist, das den Zughaken trägt und das über eine besondere hydraulische Kolben-Zylinder-Einheit einziehbar und ausfahrbar ist. Ein mit einem derartigen Ausleger versehener Bordkran beispielsweise eines Entsorgungs-LKW läßt sich jedoch nur umständlich handhaben, wobei das Einhaken der Last- und Zughaken in die Ösen von Hand erfolgen muß.For lifting and emptying waste containers with a carrying and towing eye, it is known to use a boom of a loading crane provided with a crane hook, which is provided parallel to the rope carrying the load hook with a rope running over a deflection roller which carries the towing hook and that is retractable and extendable via a special hydraulic piston-cylinder unit. An on-board crane provided with such a jib, for example of a disposal truck, can however only be handled with great difficulty, the hooking of the load and pull hooks into the eyelets having to be done by hand.

Aus der DE-A 2 521 021 (Oberbegriff des Anspruchs 1) ist bereits eine hydraulisch betätigte Hängetraverse bekannt, die zum Aufnehmen und Entleeren von Klappkübeln dient. Auch hier ist schon unterhalb eines mit Drucköl angetriebenen Drehmotors ein Tragrahmen befestigt. Seitlich an dem Tragrahmen sind jeweils mittels Kolbenzylinder-Einheiten ausschwenkbare Lasthaken angeordnet, während mittig ein vertikal verschieblicher Zughaken vorgesehen ist. Bei dieser vorbekannten Hängetraverse müssen die Last- und Zughaken über drei getrennte Kolbenzylinder-Einheiten gesteuert werden. Dadurch ist der Aufbau dieser hydraulisch betätigten Hängetraverse verhältnismäßig kompliziert.From DE-A 2 521 021 (preamble of claim 1) a hydraulically operated suspension crossmember is already known, which is used for receiving and emptying folding buckets. Here, too, a support frame is already attached below a rotary motor driven by pressure oil. Load hooks which can be swiveled out by means of piston-cylinder units are arranged on the side of the supporting frame, while a vertically displaceable pull hook is provided in the center. With this previously known suspension crossmember, the load and pull hooks must be controlled via three separate piston-cylinder units. As a result, the construction of this hydraulically operated suspension crossmember is relatively complicated.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs angegebenen Art zu schaffen, die sich einerseits einfach und schnell handhaben läßt und die andererseits einfach aufgebaut ist.The object of the invention is to provide a device of the type mentioned, which on the one hand can be handled easily and quickly and on the other hand is simple in construction.

Erfindungsgemäß wird diese Aufgabe bei einer gattungsgemäßen Vorrichtung dadurch gelöst, daß in dem Tragrahmen eine hydraulische Kolbenzylinder-Einheit angeordnet ist, deren Kolbenstange über ein Getriebe oder mindestens ein flaschenzugartig eingeschertes Seil mit dem Zughaken verbunden ist und über ein Betätigungsstück und einen an dem Arm vorgesehenen Anschlag oder Fortsatz dem Arm eine Schwenkbewegung erteilt. Und bei der Verwendung von mindestens einem flaschenzugartig eingescherten Seil ist die Länge des oder der Seile so zu bemessen, daß diese schlaff werden, wenn das Tragstück unter Schwerkrafteinwirkung gegen seinen unteren Anschlag gefahren ist, so daß dann durch weitere Einzugsbewegung des Kolbens der Arm mit dem Lasthaken ausgeschwenkt wird.According to the invention, this object is achieved in a generic device in that a hydraulic piston-cylinder unit is arranged in the supporting frame, the piston rod of which is connected to the pulling hook via a gearbox or at least one pulley-like rope and via an actuating piece and a stop provided on the arm or extension gives the arm a pivoting movement. And when using at least one pulley-like rope, the length of the rope or ropes is to be dimensioned such that they become slack when the support piece has moved against its lower stop under the action of gravity, so that the arm with the Load hook is swung out.

Die erfindungsgemäße Doppelhakeneinrichtung ermöglicht ein Ankuppeln der Last- und Zughaken an die Trag- und Zugösen des Abfallbehälters nur durch Betätigung der hydraulischen Steuerung, da sich die Haken zangenartig zum Ankuppeln an die Ösen zu schließen vermögen. Eine einfache Ausrichtung der Haken auf die Ösen ist dabei dadurch möglich, daß der die Haken tragende Tragrahmen durch den Drehmotor in die richtige Ankuppelstellung gedreht werden kann.The double hook device according to the invention enables the load and pull hooks to be coupled to the carrying and pulling eyes of the waste container only by actuating the hydraulic control, since the hooks can close like pliers to couple to the eyes. A simple alignment of the hooks on the eyelets is possible in that the support frame carrying the hooks can be rotated into the correct coupling position by the rotary motor.

Nach dem Anheben und Verbringen des Abfallbehälters in seine Entleerstellung läßt sich durch Betätigung der hydraulischen Kolbenzylindereinheit in einfacher Weise die Öffnung des Abfallbehälters bewirken, weil durch diese der Zughaken relativ zu dem Lasthaken bewegbar ist. Dabei ist das Getriebe bzw. die flaschenzugartige Einscherung des Seils so ausgelegt, daß mit relativ geringem Kolbenhub eine ausreichend große Bewegung des Zughakens erreicht wird.After lifting and moving the waste container into its emptying position, the opening of the waste container can be effected in a simple manner by actuating the hydraulic piston-cylinder unit, because the pull hook can be moved relative to the load hook by this. The gear or the pulley-like reeving of the rope is designed so that a sufficiently large movement of the pulling hook is achieved with a relatively small piston stroke.

Nach dem Entleren ist in entsprechender Weise ein einfaches Schließen und Absetzen des Behälters möglich, wobei das Auskuppeln durch erneutes zangenartiges Öffnen von Last- und Zughaken erfolgt.After emptying, a simple closing and setting down of the container is possible in a corresponding manner, the uncoupling being carried out by opening the load and pull hooks again in the manner of pliers.

Zweckmäßigerweise ist der mit dem Lasthaken verbundene Arm über eine Feder, vorzugsweise eine Druckfeder, in Richtung auf seine eingeschwenkte Hubstellung beaufschlagt, in der er gegen einen rahmenfesten Anschlag anliegt, wobei das mit der Kolbenstange verbundene Betätigungsteil den Arm im Bereich des Endes der Einzugsbewegung des Kolbens gegen die Kraft der Feder ausschwenkt. Auf diese Weise läßt sich beim Ankuppeln und Aushaken der Last- und Zughaken auf einfache Weise die zangenartige Schließ- und Öffnungsbewegung bewerkstelligen.The arm connected to the load hook is expediently acted upon by a spring, preferably a compression spring, in the direction of its pivoted-in stroke position, in which it rests against a frame-fixed stop, the actuating part connected to the piston rod engaging the arm in the region of the end of the retracting movement of the piston swings out against the force of the spring. In this way, when loading and unhooking the load and towing hooks easily accomplish the pincer-like closing and opening movement.

Ist zum Verfahren des Zughakens relativ zum Lasthaken ein Getriebe vorgesehen, weist dieses zweckmäßigerweise in seiner Endstufe ein mit einer mit dem Zughaken verbundenen Zahnstänge kämmendes Ritzel auf.If a gear is provided for moving the pulling hook relative to the load hook, it expediently has in its final stage a pinion which meshes with a toothed rack connected to the pulling hook.

Nach einer besonders bevorzugten Ausführungsform ist vorgesehen, daß die Kolbenstange an ihrem Ende jochartig mit einer Achse verbunden ist, auf der endseitig Seilrollen gelagert sind, daß an dem Rahmen die Enden von Seilen befestigt sind, deren anderen Enden an dem Tragstück des Zughakens befestigt sind, und daß die Seile von ihrem Festpunkt an dem Rahmen über die von der Kolbenstange bewegbaren Seilrollen über im oberen Bereich des Rahmens gelagerte Umlenkrollen zu ihren Festpunkten an dem Tragstück verlaufen. Durch diese flaschenzugartige Einscherung ist der Weg des Tragstücks des Zughakens in seiner Führung doppelt so groß wie der Weg der Kolbenstange, so daß eine niedrige Bauhöhe der Vorrichtung ermöglicht ist.According to a particularly preferred embodiment, it is provided that the piston rod is connected at its end in a yoke-like manner to an axle on which end pulleys are mounted, that the ends of cables are fastened to the frame, the other ends of which are fastened to the support piece of the pulling hook, and that the cables run from their fixed point on the frame via the cable pulleys movable by the piston rod via deflection rollers mounted in the upper region of the frame to their fixed points on the support piece. Due to this pulley-like reeving, the path of the support piece of the pull hook in its guide is twice as large as the path of the piston rod, so that a low overall height of the device is made possible.

Zweckmäßigerweise sind die Längen der Seile so bemessen, daß diese schlaff werden, wenn das Tragstück unter Schwerkraftwirkung gegen seinen unteren Anschlag gefahren ist, so daß dann durch weitere Einzugsbewegung des Kolbens der Arm mit dem Lasthaken ausgeschwenkt wird. Durch Schlaffwerden des Seils kann die weitere Ein- und Auszugsbewegung des Kolbens allein zum Verschwenken des Arms ausgenutzt werden, ohne daß über das Seil auch dem Zughaken eine Bewegung erteilt wird.The lengths of the ropes are expediently dimensioned such that they become slack when the support piece has moved against its lower stop under the action of gravity, so that the arm with the load hook is then pivoted out by further retraction movement of the piston. By slackening the rope, the further retraction and extension movement of the piston can be used solely for pivoting the arm, without the towing hook also being given any movement.

Zweckmäßigerweise ist der Drehmotor mit durchgehenden Speise- und Rückführleitungen für die Druckmittelkolben-Zylinder-Einheit versehen, so daß keine mitdrehenden Schläuche vorgesehen werden müssen, die durch Überdrehen beschädigt werden könnten.The rotary motor is expediently provided with continuous feed and return lines for the pressure medium piston-cylinder unit, so that there is no need to provide rotating hoses which could be damaged by overtightening.

Nach einer weiteren Ausgestaltung ist vorgesehen, daß der Lasthaken mit einem mit Zapfen versehenen Fortsatz versehen ist, der in einem übergreifenden Rohr teleskopartig verschieblich geführt ist, wobei der Verschiebeweg dadurch begrenzt ist, daß die Zapfen in Langlöcher des Rohrs greifen. Beim Absenken stützen sich die Zapfen auf den unteren Enden der Langlöcher ab. Stößt der Lasthaken beim Absenken der Vorrichtung auf die Deckwandung des Behälters, wird dieser nicht beschädigt, weil sich der Lasthaken in den Langlöchern nach oben verschieben kann.According to a further embodiment it is provided that the load hook is provided with a projection provided with a pin, which is telescopically guided in an overlapping tube, the displacement path being limited by the fact that the pins engage in elongated holes in the tube. When lowering, the pins are supported on the lower ends of the elongated holes. If the load hook hits the top wall of the container when the device is lowered, it will not be damaged because the load hook can move upwards in the elongated holes.

Bei der erfindungsgemäßen Vorrichtung erfolgt das Einklinken des Lasthakens in die Tragöse nach Freigabe des schwenkbaren Hebels durch den mit der Kolbenstange verbundenen Querträger durch Federkraft. Das spätere Ausklinken erfolgt durch Mitnahme eines an der Kolbenstange vorgesehenen Ansatzes. Während des Ein- und Ausklinkens führen die Haken keine vertikale Hakenbewegung aus. Die Kolbenstange befindet sich an ihrem unteren Totpunkt und die von dieser bewegten Seile sind schlaff. Das Ein- und Ausklinken erfolgt durch eine zangenartige Bewegung der Last- und Zughaken.In the device according to the invention, the load hook is latched into the lifting eye after the pivotable lever has been released by the cross member connected to the piston rod by spring force. The subsequent release is carried out by taking along an attachment provided on the piston rod. The hooks do not perform a vertical hook movement while being latched in and out. The piston rod is at its bottom dead center and the ropes moved by it are slack. The latches are released and released by a pincer-like movement of the load and pull hooks.

An die äußeren Bereiche der Bodenklappen 3, 4 sind die Enden von Seilen 5, 6 befestigt, deren anderen Enden mit einer Zugstange 7 verbunden sind, die in Führungen des Behälters längsverschieblich geführt ist. Die Zugstange 7 durchsetzt die obere Behälterwandung und trägt an ihrem oberen Ende die Zugöse 8. Etwa parallel zu der Zugöse 8 und etwas höher als diese ist die Tragöse 9 angeordnet, die mit der glockenförmigen Behälterwanne verbunden ist. Zum Anheben des Recycling-Behälters und zu dessen Versetzen und Verschwenken sowie Öffnen ist in die Tragöse 9 der Lasthaken 10 und in die Zugöse 8 der Zughaken 11 einhakbar.The recycling container 1 shown schematically in FIGS. 1 to 5 is provided with two bottom closure flaps 3, 4 which can be pivoted about a horizontal axis 2. In the case of recycling containers set down on the ground, the bottom closure flaps 3, 4 are kept closed under the weight of the bell-shaped housing of the container resting on them. The ends of ropes 5, 6 are attached to the outer regions of the bottom flaps 3, 4, the other ends of which are connected to a pull rod 7 which is guided in longitudinally displaceable fashion in guides of the container. The pull rod 7 passes through the upper container wall and carries the pulling eye 8 at its upper end. Approximately parallel to the pulling eye 8 and somewhat higher than this, the carrying eye 9 is arranged, which is connected to the bell-shaped container trough. For lifting the recycling container and for moving and pivoting and opening it, the load hook 10 can be hooked into the lifting eye 9 and the pull hook 11 into the lifting eye 8.

Die eingehakte Stellung ist aus Fig. 2 ersichtlich.The hooked position is shown in Fig. 2.

Vor dem Anheben des Recycling-Behälters fährt der Zughaken in der aus Fig. 3 ersichtlichen Weise nach oben, so daß die Seile 5, 6 gestrafft und die Bodenklappen 3, 4 in ihrer Verschlußstellung gehalten sind.Before lifting the recycling container, the pulling hook moves upwards in the manner shown in FIG. 3, so that the ropes 5, 6 are tightened and the bottom flaps 3, 4 are held in their closed position.

Befindet sich der Recycling-Behälter 1 in der aus den Fig. 4 und 5 ersichtlichen Weise oberhalb eines Aufnahmebehälters, fährt der Zughaken 11 in der aus Fig. 5 ersichtlichen Weise nach unten, so daß sich die Bodenklappen 3, 4 in der dargestellten Weise unter der Schwerkraftwirkung öffnen können.If the recycling container 1 is located above a receptacle in the manner shown in FIGS. 4 and 5, the pulling hook 11 moves downward in the manner shown in FIG. 5, so that the bottom flaps 3, 4 are underneath in the manner shown of gravity can open.

In umgekehrter Reihenfolge wird der entleerte Behälter sodann wieder auf den Boden abgesetzt.The emptied container is then placed back on the floor in reverse order.

Anders als anhand der Fig. 1 bis 5 erläutert, gibt es auch Recycling-Behälter, bei denen die Bodenklappen oder schwenkbare mit Bodenteilen versehene Seitenteile zu ihrem Öffnen und Schließen mit Gestängen verbunden sind, wobei das Öffnen durch Auziehen der mit der Zugöse verbundenen Zugstange erfolgt. Die nachfolgend beschriebene Vorrichtung bezieht sich auf einen mit einem derartigen Öffnungsmechanismus versehenen Recycling-Behälter.Unlike explained with reference to FIGS. 1 to 5, there are also recycling containers in which the bottom flaps or pivotable side parts provided with bottom parts are connected to rods for their opening and closing, the opening taking place by pulling out the pull rod connected to the drawbar eye . The device described below relates to a recycling container provided with such an opening mechanism.

Die in den Fig. 6 bis 11 dargestellte Vorrichtung weist einen oberen Tragrahmen 20 auf. Dieser besteht aus einem jochartigen Querträger 21, der endseitig mit U-Profilen 22, 23 verschweißt ist, die die Führungen für das Tragstück 24 für den Zughaken 25 bilden.The device shown in FIGS. 6 to 11 has an upper support frame 20. This consists of a yoke-like cross member 21 which is welded at the end to U-profiles 22, 23 which form the guides for the support piece 24 for the pull hook 25.

In seinem mittleren Berich ist der Träger 21 mit zwei schräg nach unten verlaufenden Stegblechen 27, 28 verschweißt, die an ihrem unteren Ende durch ein eingeschweißtes Blech 29 miteinander verbunden sind. Die Stegbleche 27, 28 sind weiterhin mit zwei diese nach unten hin überragenden Laschen 30, 31 verschweißt, die mit Lagerbohrungen 32, 33 für eine Welle oder Achse versehen sind, auf der der Arm 34 des Lasthakens 35 schwenkbar gelagert ist.In its central region, the carrier 21 is welded to two web plates 27, 28 which run obliquely downward and which are connected to one another at their lower end by a welded-in plate 29. The web plates 27, 28 are further welded with two tabs 30, 31 which project downwards and which are provided with bearing bores 32, 33 for a shaft or axis on which the arm 34 of the load hook 35 is pivotably mounted.

Weiterhin sind im Bereich der Enden des Trägers 21 paarweise gabelförmig aufragende Lagerbleche 37, 38 aufgeschweißt, zwischen denen die oberen Umlenkrollen 39, 40 auf entsprechenden Achsen gelagert sind.Furthermore, bearing plates 37, 38 protruding in pairs in the form of a fork are welded in the area of the ends of the carrier 21, between which the upper deflection rollers 39, 40 are mounted on corresponding axes.

Auf dem die Stegbleche 27, 28 verbindenden Blech 29 ist der Zylinder 41 befestigt, dessen Kolbenstange das Blech 29 nach unten hin durchsetzt. Die Kolbenstange 46 ist mit einem jochartigen Querträger 47 verschweißt, auf dem endseitig die Seilrollen 44, 45 gelagert sind.On the sheet 29 connecting the web sheets 27, 28, the cylinder 41 is fastened, the piston rod of which penetrates the sheet 29 downwards. The piston rod 46 is welded to a yoke-like cross member 47 on which the cable pulleys 44, 45 are mounted at the end.

An dem die Stegbleche 27, 28 verbindenden Tragblech 29 sind durch die Befestigungseinrichtung 50 die Enden von Stahlseilen 51 befestigt, die über die beweglichen Seilrollen 44, 45 und die rahmenfesten Seilrollen 39, 40 zu ihren Befestigungspunkten an dem in dem U-Profilen 22, 23 geführten Tragstück 24 für den Zughaken 25 verlaufen. Der Befestigungspunkt an dem Tragstück 24 für die Zugseile 51 ist in Fig. 6 mit 56 bezeichnet.On the support plate 29 connecting the web plates 27, 28, the ends of steel cables 51 are fastened by the fastening device 50, which via the movable cable pulleys 44, 45 and the frame-fixed cable pulleys 39, 40 to their fastening points on the in the U-profiles 22, 23 guided support piece 24 for the pull hook 25. The attachment point on the support piece 24 for the traction cables 51 is denoted by 56 in FIG. 6.

Der Tragarm 34 für den Lasthaken 35 ist in der aus den Fig. 6 und 7 ersichtlichen Weise auf der Schwenkwelle 60 befestigt, die in den Lagerbohrungen 32, 33 der Lagerlaschen, 30, 31 schwenkbar gelagert ist. Der Tragarm 34 ist in der aus Fig. 6 ersichtlichen Weise mit einem Fortsatz 63 versehen, der einen Zapfen 64 aufweist, der der Halterung einer nicht dargestellten Druck feder dient, die zwischen dem Fortsatz 63 und dem rahmenfesten Widerlager 65 eingespannt ist.The support arm 34 for the load hook 35 is fastened in the manner shown in FIGS. 6 and 7 on the pivot shaft 60 which is pivotably mounted in the bearing bores 32, 33 of the bearing plates 30, 31. The support arm 34 is shown in FIG. 6 with an extension 63 which has a pin 64 which serves to hold a pressure spring, not shown, which is clamped between the extension 63 and the frame-fixed abutment 65.

Aus Fig. 6 ist ersichtlich, daß der die beweglichen Seilrollen 44, 45 tragende jochartige Querträger beim Einfahren der Kolbenstange 46 über den Fortsatz 63 den Arm 34 ausschwenkt, so daß dieser eine zangenartige Bewegung ausführen kann. Die eingeschwenkte Hubstellung ist in vollen Linien dargestellt, während die ausgeschwenkte Stellung gestrichelt ersichtlich ist. Fährt das Querjoch 34 unter Spannung des Seils 51 nach unten, gibt der Querträger 47 den Fortsatz 63 frei, so daß der Arm 34 unter der Wirkung der Druckfeder relativ zu dem Zughaken 25 eine zangenartige Schließbewegung ausführen kann. Fährt der Querträger 47 weiter nach unten, wird das Zugseil 51 gespannt und dementsprechend der Spannhaken 25 angehoben, in dem das Tragstück 24 in den Führungen 22, 23 nach oben fährt.From Fig. 6 it can be seen that the yoke-like cross member carrying the movable rope pulleys 44, 45 swings out the arm 34 when the piston rod 46 is retracted via the extension 63, so that it can perform a tong-like movement. The swiveled-in stroke position is shown in full lines, while the swiveled-out position is shown in dashed lines. If the transverse yoke 34 moves downwards under tension of the cable 51, the cross member 47 releases the extension 63, so that the arm 34 can perform a pliers-like closing movement relative to the pull hook 25 under the action of the compression spring. If the cross member 47 moves further down, the traction cable 51 is tensioned and accordingly the tensioning hook 25 is raised, in which the support piece 24 moves upwards in the guides 22, 23.

Der Querträger 21 des Rahmens 20 ist weiterhin in seinem mittleren Bereich mit einer Aufnahmeöse versehen, in der die Abtriebswelle 70 des Drehmotors 71 befestigt ist. Dieser ist an seinem oberen Ende zwischen gabelartigen Schenkeln mit einer Bohrung 72 versehen, die der Befestigung des Drehmotors an dem Ausleger eines Ladekrans dient.The cross member 21 of the frame 20 is also provided in its central region with a receiving eye in which the output shaft 70 of the rotary motor 71 is fastened. This is provided at its upper end between fork-like legs with a bore 72, which is used to fasten the rotary motor to the boom of a loading crane.

In Fig. 6 ist weiterhin der Spannhaken 25, der mit dem Tragstück 24 verschweißt ist, dargestellt. Befindet sich der Spannhaken 25 in seiner oberen Stellung, hat die Kolbenstange 46 die Seilrollen 44, 45 in der dargestellten Weise in die unterste Stellung ausgefahren.6, the tensioning hook 25, which is welded to the support piece 24, is also shown. If the tensioning hook 25 is in its upper position, the piston rod 46 has extended the rope pulleys 44, 45 into the lowest position in the manner shown.
