Device for bringing control stands to the desired location.

The invention relates to a device for handling material, which consists of a structure with a boom and a transport vehicle carrying the structure. The boom can with a Provide tools or dishes for material handling. be the one at the cantilever end of the boom is attached or under the boom on suitable means, such as a cable, is usually located the largest cross-section of the boom in this type of device is at or near the point which of the booms is pivotally attached to the extension. Such devices eur material handling can over Rails or public roads are transported. However, this type of transport was used for the devices can be, certain limitations must be observed in the dimensions, in particular in the cross-sectional size will. The restrictions on the cross-sectional flow or the width of the material handling devices limits the distance between the operator cabin and others Obstructions protruding from the center line of the boom.

Material handling devices inserted the operator cabin into the structure and close to one side of the structure located at the end of the boom and away from the centerline of the boom.

Devices of this type either have a wide boom base or a wide supporting structure for the boom, which cannot be made tight enough to run on rails or public roads can be transported without the operator cabin to be arranged behind the boom and thereby the operator's view of the protruding end of the boom, to obstruct or restrict the tool and the work area. Boom footprint and arrangement, which carries the boom with this arrangement of the cabin, blocks the operator from paying attention to the material handling area. So far, the cabin was rigidly attached to the structure. This arrangement was a compromise between the desired working position and the desired Transport position.

The invention aims to remedy the limitation to a fixed assembly by the provision of a Baäienkabine which a Bewegungsmöglichkci "In the lateral direction against the structure ^and; on is · set up the structure away allowing the device to a small size can have during transport and. A large protrusion of the cabin is permitted during work in order to give the operator a good view of the trailer and the tools.

It is a further object of the invention to attach a control cabin via arms of equal length, so that the operator cabin a translational movement between a smallest total width of the structure resulting = indentation in the structure for transport and an overhanging position to achieve a largest View for operation while the device is working.

Another object of the invention is to provide an operator's cabin which is in one plane can be moved without rotation on the structure and is connected to the structure via a central strand, which contains a device transferring control.

Another object of the invention consists in providing a translationally movable operator cabin ^{1 located} therein controls for controlling the movement of a tool on the boom, the boom on the body and the movement of the body on the transport vehicle.

In addition, the invention provides a control cabin which nests in the structure for transport and unloads for better visibility at work. There is such a movement force controlled and without losing control of the device while moving from the extended position in the withdrawn position.
