Abstract

In the case of this device, a two-armed supporting arm (1) is supported in the ceiling retention device (2) such that it can rotate. The shorter arm, which is designated a force arm (5) is supported via a rocker (7) on the lower end wall of a hydraulic bellows (6). The upper end wall presses against the contact surface (8) of the ceiling retention device (2). A hydraulic line (9) having a hydraulic valve (10) connects the interior of the bellows to a pressure tank (11) which is filled with gas (14) above a hydraulic level (13). Gas is introduced into the pressure tank (11), in order to lift the load arm (3), via a valve (16), and gas is blown out via a valve (17) for lowering. This results in it being possible to move the load arm (3) into a stable position, in any position, directly from the lifting or lowering phase. <IMAGE>
