Lifting gear, especially after. Kind of an Erans

The invention relates to a hoist, in particular according to. Kind of a crane that puts you on the platform of a self-propelled Vehicle or on a stationary plane or support attached main ring has the rotatable is mounted to move at least one oil hydraulic reduction motor or other appropriate Serving means.

The present invention is directed to a hoist of the The type in question here, which has two booms or working arms mounted on the same rotatable platform, which can be controlled either simultaneously or independently.

The crane-shaped hoist devices used in various fields of work are generally with equipped with a single, extendable boom or working arm, for the purpose of its angular adjustment on a rotatable platform or on a corresponding one Tower is arranged.

The purpose of the present invention is to provide a crane-shaped To create a hoist that has two extendable working arms that are both independent of each other as well are adjustable and orientable together. Man

intended in this way more versatile and practical Get more rational uses.

Another object of the present invention is to provide a two-arm crane which preferably can be placed on. self-propelled vehicles to a to form a so-called truck crane, which can also be used with advantage as a stationary device Vierden can.

Another purpose of the present invention is also to provide an apparatus of the type in question here Art to create in various fields of work can be used, e.g. for inserting or placing cables or prefabricated elements, for the pecking down from the lane ef vehicles and generally for lifting and moving bodies and loads of considerable length that are simultaneously in two zones must be recorded in order to be adjusted in a balanced state.

The above purposes are achieved with the device according to the present invention, which is described below under Will be described with reference to the drawing. In the drawing is an embodiment of the subject of the invention shown. Show it:

Pig. 1 shows a device according to the invention in a side view in use, for example on a Support platform of a motor vehicle,

Prop. 2 and 3 the device according to ^{S 1 Xg.} 1 seen from the side "or from above, each on a larger scale and

the pig. 4- the means of controlling / independent Rotational movements of the two arms in a schematic representation.

In the drawing, Λ denotes the support platform, for example of a motor vehicle, on which an input 2 with internal toothing is provided, which is rotatably mounted and can be rotated with the aid of an oil-hydraulic gear motor 3, the gear wheel of which is connected to the toothing of the Hinges intervenes. A horizontal platform 4 is rigidly attached to Sing 2, which can be rotated with it and protrudes like a cantilever on one side of the Hinges and which has 2 tower-like rotatable supports 5 ₅ 6 at its free end, each of which has a working arm 7 or 8 is articulated.

Essentially, the hanging 2. and the tower-like supports 5j 6 rotate independently of one another around the corresponding one to the other parallel and spaced perpendicular axes, and while the position of the Hinges is stationary, adjust the two # Q towers thanks to the rotating platform 4

with a planetaxial movement around the axis of the ring hereabouts.

The tournament-like carriers 5? 6 are each provided with bearing rings 9 and 10 which are controlled independently of one another in order to determine and effect the independent rotary movement of the carriers with the corresponding working arms 7j 8. The control of each bearing ring 9 »Io of the tower-like carriers 5» 6 can either 2 and 4 of the drawing, this cable or chain is in a circumferential groove of the corresponding ring and guided on one or more pulleys 12, with a single double-acting cylinder or two single-acting cylinders 13 and 14 engaging the chain or the cable, which counteract each other at the two ends of the chain or the cable or cable.

Each working arm 7 »8 is known per se on one side Extendable with the help of an extension cylinder 15, while on the other hand it is rotatable with the corresponding tower-like support unjin vertical planes with With the help of a cylinder 16 to regulate the angle of the arm angularly is adjustable.

Finally, the means for controlling the device, generally designated 17 , are also on the rotatable platform 4.

device and a seat 18 is provided for the operator who, thanks to its position, has a complete overview of the The device's field of work.

The mode of operation of the device described above is varied follows:

The two working arms 7? 8 are at the same time in a horizontal plane along an uninterrupted arc of 56o ° by rotating the Singes 2 and with this the platform 3 adjustable in such a way that they the arms 7 and 8 from case to case with respect to the direction of travel of the vehicle in the Adjust and orientate the most favorable position for performing the operation. On the other hand, these working _{arms 7 5} 8 can also be rotated independently of one another by rotating the corresponding tower-like beams 5) 6 in such a way that the arms can be set apart or spread apart or brought together up to 180 °. In addition, each of the working arms can be extended and tilted independently of the other, which is why the device in its entirety is suitable for picking up, lifting, balancing, orienting and positioning any body, even of considerable length, through operations that are practically impossible with the lifting equipment known per se can be executed.

This results in the great variety in the application of the device described above and its ability to carry out the To simplify operations in order to also reduce the times and

909832/0585

to reduce frustration ..

Finally, even if in the previous description, reference was made to a device for lifting there are no two arms attached to the support platform of a motor vehicle so that it is self-propelled Concern, however, that the same device is also stationary, without thereby the advantages and the performance capabilities of the device resulting from the above features, and without departing from the scope of the present invention Invention came out.
