Abstract
A power operated drive shaft and brake assembly are coaxially mounted for rotation inside a cable drum which is coupled to the drive shaft through gearing. The brake assembly has an adapter housing and one-way clutch for drivingly connecting the drive shaft and adapter housing during a "cable out" operation. A plurality of brake pads are mounted for movement relative to the brake adapter housing. The brake pads are angularly offset in a non-radial orientation to negate undesired brake drag caused by centrifugal forces while the pads are spring loaded to provide a predetermined braking force to hold a load in place after completion of a winching operation.
