摘要

The mobile device consists of a stand, an upright frame fastened to it, and a suction hood connected to a suction device. The frame (3) is at least partially moveable relative to the stand (2) via a joint device (8), by a motor-driven adjusting unit (10). The frame consists of a lower (6) and upper part (9), which are relatively moveable by the joint device. A further adjusting device (13) is located between suction hood (4) and frame. The motor-driven suction device (18) is located on the foot behind the frame on the side away from the suction hood. Distance elements (14) under the foot define free spaces (15) for the forks of forklift trucks.
