ABSTRACT:
A winch control system for a crane or the like; the winch including a rotatable spool. A motor is connected for rotating the spool while a dual state brake is connected to prevent spool rotation in one state while permitting spool rotation in its other state. A power source provides energy to drive the motor and to change the state of the brake. Control elements selectively interconnect the power supply with the brake and motor, the interconnection of the power supply and motor being responsive to the interconnection of the brake and power supply.
