ABSTRACT:
A positioning arrangement for use with a device having a fixed or movable crane arm includes a suction device for plate-shaped bodies which hangs from the free end of the crane arm, the suction device being provided with a tilting device. The tilting device is infinitely variable by a setting mechanism. In this way, the center of gravity of the suction device with the plate-shaped body attached by suction may be adjusted such that the plate-shaped body is kept vertically.
