Abstract

Control device of a winch coupled to a hydraulic drive motor, which includes two conduits respectively and selectively connected by means of a distributor of at least two positions, the first to a source of fluid under pressure in the position of the distributor corresponding to rotation of the winch, and to a discharge tank in the position of the distributor opposite to that of rotation, the second with the discharge tank and the source of fluid under pressure, while said control device includes a safety brake provided with a control member selectively connected by a third conduit to said source of fluid under pressure and to said discharge tank, characterized in that a calibrated valve is arranged in said first conduit, downstream of the connection of said third conduit with the discharge of the source of fluid under pressure relative to said source of fluid under pressure.
