ABSTRACT:
The invention relates to a hoist for motor vehicles, with at least two vertically displaceable columns having on their upper end a support surface for receiving the vehicle, where in a retracted state the columns are disposed below the ground in a pit and the support surface is located approximately at the level of a shop floor. In order to make do with a reduced depth of the pit while retaining the same lifting height of the columns, the columns comprise an interior, vertically displaceable lift element supporting a deflection roller for operation of a cable on its upper end. One end of the cable is attached fixed in place, while the other end of the cable is fastened to a support pipe with a support surface which is vertically displaceable in relation to the lift element, where a sleeve, displaceable in relation to the support pipe, is provided which acts as a telescopic guide when the column is extended.
