Abstract (en)

[origin: EP0872293A2] The machine frame (2) accommodates a plate (5) which in one plane is controllably pivotable around an axis (23). The axis is at the end of the plate and the drive device for activation of the pivot movement is effectively connected with the plate. An installation for permanent control is provided for the drive device. A shaft (6) is provided, which extends away from the lower surface (7) of the plate. The shaft is rotatably accommodated by the machine frame and is effectively connected to the drive device. Roller bearings (100, 101) are arranged on the shaft and are located in recesses of the machine frame. The drive device for carrying out the pivot movement is arranged on the machine frame in the form of a piston-cylinder unit and the piston is effectively connected with the plate.
