摘要

The device (10) has a suction hose (20) comprising an end (18) connected with a low pressure supply (30) and another end (22) connected with a suction terminal (23), where the suction hose guides low pressure. The suction terminal is provided outside of a profiled element (12). The suction hose is retracted into the profiled element. The profiled element is designed as a crane arm or a crane column. An aerator is provided at the suction terminal for ventilating the suction hose. A cylinder (14) for a piston (16) is provided in the profiled element.
