摘要
Provision of a damped delay of a lifting vehicle's hoist and particularly of a forklift truck's fork, in order to avoid vibration and over-swing of the lifting device and resulting in greater working safety. The control device uses at least one check valve (14) which includes a main valve body (16) which operates in conjunction with a main valve seat (18) and with a pilot control valve body (22) actuated by a positional element (20) and which operates in conjunction with a pilot valve seat (24). A component (ring) (34) arranged on the pilot valve body provides the required reduction of the throttling cross-section during closure of the pilot valve body.
