Abstract

Improvements in the winches of security, of automatic type with a drum with brakes, a system of gears, a piston pump with a device to control the flow of the pump according to the pressure, driven by an electric motor, characterized by that to transmit the motor torque to the drum is applied a hydraulic motor (6) of high torque, which in a sense of rotation acts as a motor, and in the opposite direction of rotation acts as a pump.
