Es sind Drehkräne mit mehrteiligem Ausleger bekannt, die auf Eisenbahnwagen oder auf Wagen mit luftbereiften Rädern oder Gleisketten montiert sind. Bei einer Art von bekannten Drehkränen sind die Teile des Auslegers lediglich teleskopartig ineinanderschiebbar. Nachteilig ist hierbei, daß der innerste Teil des Auslegers sehr groß ausgebildet sein muß, da dieser sämtliche andere Teile des Auslegers in sich teleskopartig aufnehmen muß. Bei einer anderen Art von Drehkränen sind alle Teile des Auslegers zueinander klappbar. Bei diesen Drehkränen kann der Arbeitsbereich längs des Auslegers nicht verändert werden, da die Länge des Auslegers im Betrieb festliegt. There are slewing cranes with multi-part booms known, which are mounted on railway wagons or on wagons with pneumatic wheels or crawlers. In one type of known rotary cranes, the parts of the boom can only be telescoped into one another. The disadvantage here is that the innermost part of the boom must be made very large, since this must accommodate all other parts of the boom in a telescopic manner. With another Type of slewing cranes, all parts of the boom can be folded towards each other. With these slewing cranes the working area along the boom cannot be changed, as the length of the boom is fixed during operation.

Demgegenüber ist bei einem Drehkran mit schwenkbarem, mindestens dreiteiligem Ausleger, dessen Teile zueinander bewegbar sind, gemäß der Erfindung vorgesehen, daß zwei Teile des Auslegers teleskopartig ineinanderschiebbar und zwei Teile zueinander klappbar sind. Durch dieses kombinierte Klappen der Teile zueinander und Einschieben der Teile ineinander kann der Ausleger bei nicht zu aufwendiger Ausgestaltung auf engem Raum zusammengelegt werden. Ebenfalls ergibt sich ein vielfältig veränderbarer Arbeitsbereich des Kranes. Gegenüber Drehkränen mit lediglich teleskopartig ineinanderschiebbaren Teilen ergibt sich der Vorteil, daß der eine Teil bei gleichbleibender Tragfähigkeit nicht sehr groß ausgebildet sein muß, da er nur einen Teil teleskopartig in sich aufnimmt. Gegenüber Drehkränen mit nur zueinander klappbaren Teilen ergibt sich der Vorteil, daß der Arbeitsbereich des Kranes durch die beiden teleskopartig ineinanderschiebbaren Teile in Längsrichtung des Auslegers veränderbar ist.In contrast, a slewing crane with a swiveling, at least three-part boom, whose parts are movable relative to one another, according to the invention, there are two parts of the boom Can be telescoped into one another and two parts can be folded towards one another. Combined by this Folding the parts towards one another and pushing the parts into one another can be done by the boom without being too expensive Design can be merged in a small space. There is also a multifaceted result changeable working area of the crane. Compared to slewing cranes with telescopic ones that can only be telescoped into one another Sharing has the advantage that one part does not have the same load-bearing capacity must be made very large, since it only accommodates part of it telescopically. Opposite slewing cranes with parts that can only be folded towards one another, there is the advantage that the working area of the crane can be changed in the longitudinal direction of the boom by the two telescopically telescoping parts.

Gemäß der weiteren Erfindung ist vorgesehen, daß bei dreiteiligem Ausleger in den durch eine Hydraulik an der Kransäule anhebbaren Innenteil der Mittelteil einschiebbar ist und daß der mit einem Lastaufnahmemittel versehene Außenteil zu dem Mittelteil· in einer horizontalen Ebene (bei waagerechter Stellung des Auslegers) klappbar ist.According to the further invention it is provided that with a three-part boom in the by a hydraulic the inner part, which can be raised on the crane column, of the central part can be pushed in, and that the one with a load-bearing means provided outer part to the middle part · in a horizontal plane (with horizontal Position of the boom) is foldable.

Drehkranes aus drei Teilen 6, 7 und 8, die miteinander beweglich verbunden sind. Sämtliche Teile sind als röhrenförmige Gitterkonstruktionen ausgeführt.Rotary cranes made up of three parts 6, 7 and 8, which are movably connected to one another. All parts are designed as tubular lattice structures.

Der Außenteil 6 ist an dem Mittelteil 7 durch herausnehmbare Bolzen 9 befestigt. Wenn einer dieser Bolzen herausgenommen wird, wirkt der andere als Scharnier, das eine Schwenkung des Außenteiles 6 in waagerechter Ebene bis in die Stellung der Fig. 3 erlaubt. Der Mittelteil? läßt sich in den Innenteil8 einschieben und kann durch Arretierungsbolzen festgehalten werden.The outer part 6 is fastened to the central part 7 by removable bolts 9. If any of these When the bolt is removed, the other acts as a hinge that allows the outer part 6 to pivot in horizontal plane up to the position of FIG. 3 allowed. The middle part? can be inserted into the inner part8 slide in and can be held in place by locking bolts.

An dem freien Ende des Innenteiles 8 sind bei 10 a und 11a Zugstangen 10 und 11 angelenkt, deren entgegengesetzte Enden 10 & und 11 & an Seitenständern 12 angelenkt sind. Die Seitenständer 12 sind an einem Rohr 13 befestigt, das gegenüber einem Hydraulikzylinder 14 zwar drehbar, aber nicht verschiebbar ist. In dem Zylinder 14 ist koaxial ein Kolben 15 angeordnet, an dessen Kopf eine TragplatteAre at the free end of the inner member 8 at 10a and 11a, tie rods 10 and 11 articulated, the opposite ends are hinged to the uprights 12 & 10 and 11. The side stands 12 are attached to a tube 13 which, although rotatable with respect to a hydraulic cylinder 14, is not displaceable. A piston 15 is arranged coaxially in the cylinder 14 and has a support plate on its head

16 für eine Stützrolle 17 befestigt ist. Die Stützrolle16 is attached for a support roller 17. The support role

17 ist am Innenteil 8 drehbar gelagert. Am oberen Ende des Innenteils 8 ist eine Umlenkrolle 19 für ein Seil 20 gelagert, dessen eines Ende 20 α am Rohr 13 befestigt ist und dessen anderes Ende über eine zweite Umlenkrolle 21 einen Greifer 22 trägt.17 is rotatably mounted on the inner part 8. At the upper end of the inner part 8 is a pulley 19 for a Rope 20 stored, one end of which is 20 α attached to the tube 13 and the other end via a second deflection roller 21 carries a gripper 22.

In Fig. 2 ist der Zustand beim Beginn der Hubbewegung des Auslegers 6, 7 und 8 dargestellt, die von der Hydraulik 14, 15 ausgelöst wird.In Fig. 2, the state at the beginning of the lifting movement of the boom 6, 7 and 8 is shown, which is triggered by the hydraulic system 14, 15.

Gemäß Fig. 4 ist am Ende des Armes 23 eine Schaufel 34 angebracht. Wenn der Zylinder 14 um 180° gedreht wird, ist der Mittelteil 7 des Kran-According to FIG. 4, a shovel 34 is attached to the end of the arm 23. When the cylinder is 14 to Is rotated 180 °, the middle part 7 of the crane

Der Ständer 31 weist Feststellöffnungen a,b,c...f auf, wodurch die Feststellung des Hydraulikzylinders 24 zwischen dem Ständer 31 und dem Arm 23 in der gewünschten Höhe möglich ist. Der Arm 23 ist mit Feststellöffnungen a°, bn, c°... f° versehen.boom completely withdrawn. The stand 31 has locking openings a, b, c ... f , whereby the locking of the hydraulic cylinder 24 between the stand 31 and the arm 23 is possible at the desired height. The arm 23 is provided with locking openings a °, b n , c ° ... f °.

Bei dieser Anordnung hat die Schaufel 34 große Bewegungs- und Arbeitsmöglichkeiten. Sie kann nicht nur vom Schlepper^0 aus, auf dem der die Schaufel tragende Kran aufgebaut ist, sondern auch durch die Hydraulik 14, 15 in der Vertikalebene und wahlweise durch den Hydraulikzylinder 24 in der Horizontalebene bewegt werden.With this arrangement, the bucket 34 has great freedom of movement and work. It can not only be moved from the tractor ^ 0 on which the crane carrying the shovel is built, but also by the hydraulics 14, 15 in the vertical plane and optionally by the hydraulic cylinder 24 in the horizontal plane.

Der erfindungsgemäße Kran ist so ausgebildet und bemessen, daß er auf Kranunterwagen oder Kraftfahrzeuge aufgebaut werden kann. Er kann viele Aufgaben als Hebe- und Fördermittel für schwere Lasten erfüllen und als Bagger für Hebe- oder Schürfarbeiten eingesetzt werden, wobei er dann vor dem Kraftfahrzeug montiert wird (s. Fig. 4). Der Kran kann auch für das Heben und Kippen des Lastwagenkastens, auf dem er aufgebaut ist, eingerichtet werden.The crane according to the invention is designed and dimensioned so that it can be used on crane undercarriages or motor vehicles can be built. It can do many tasks as lifting and handling equipment for heavy lifting Fulfill loads and be used as an excavator for lifting or digging work, which he then before the motor vehicle is mounted (see Fig. 4). The crane can also be used for lifting and tipping the truck body, on which it is built.

Für Verwendungszwecke des Kranes, die das Heben von Lasten entlang einer senkrechten Linie mittels starrer Auslegeglieder bzw. Seilen, die an ihrem Ende Greiforgane tragen, erfordern, werden besondere Ausgleichs-Hebelgestänge an den Ausleger 6, 7, 8 angebaut.For uses of the crane that require the lifting of loads along a vertical line by means of rigid extension members or ropes that carry gripping members at their end, special compensating lever linkages are attached to the extension arms 6, 7, 8.
