A branch line (15) branches off from the pressurized medium line (6) to a container (5). A lowering valve (16) for controlling the lowering movement in the fine control range is mounted in the branch line. the lowering valve can be a proportional valve. The electric motor can be an asynchronous motor or direct current motor.
