A pump device (5 lowers the pressure in the tubular or hose-shaped component (2) via a connection (4). A manoeuvring component (17) regulates the pressure. A second tubular or hose-shaped component (13) can be contracted at least in an axial direction and is telescopically arranged in relation to the first component (2). It incorporates a suction head (14, 15) for connection to the object. |
