Hydraulic lift for raising and lowering loads

摘要

A cable (10) is included which can be detachably clamped on at least two holders (60) supportable against the load. One of the two holders is movable by the piston cylinder unit (18) when the cable is released against the predetermined direction of movement of the cable and when the cable is clamped, in the predetermined direction of movement. The cable is firmly clamped on the other holder and this holder is supported against the load when the cable and first holder are released from each other. The piston cylinder assembly (18) can have several such units (40,41).
