Abstract

The device comprises a check valve (7) which is hydraulically releasable by means of a control connection (9) and which opens when operating pressure is present at the control connection (9). The piston-side chamber of the lift cylinder and the control connection of the check valve are connected to the control valve (3). The rod-side chamber of the lift cylinder is connected via the check valve in its closure direction with the pressure accumulator (8).
