Abstract

A hoist cable drum control having a spring set, normally engaged drum brake and a variable torque converter for driving the drum, in which a control device initiates cable take-up and slips the brake, and drum rotation is sensed to thereafter disengage the brake. Control forces on the converter and the brake are proportional so that as torque is reduced the brake comes on smoothly. Cable is payed off the drum through a reverse driving hydraulic motor actuated simultaneously with release of the brake and capable of being overridden by the torque converter to control "lowering" movement. A clutch engaged by initial operation of the control device permits multiple drums to be driven by the converter.
