Abstract

The winch drum is driven by an electric motor and the brake consists of a member fixed to the winch shaft and a second and non-rotating spring-loaded member pressed against the first member. The brake is released by an electromagnet in the motor circuit. A secondary shaft is rotated by a manually-operated mechanism and also caused to slide axially under the effect of a cam mechanism. Sliding of this shaft engages it with the shaft carrying the brake member, whereupon a plate on the secondary shaft pulls the second member free of the first. Thus the brake can be released to lower the load in the event of failure of the electric supply.
