ABSTRACT:
At predetermined low speeds, a safety brake is applied directly to the hoisting drum at a setting sufficiently high to stop the load from falling should drive line failure occur. The load can be lowered or raised by applying sufficient torque to the drum to overcome the braking force and thus lower or raise the load. If drive train failure occurs, the brake will instantaneously stop the load without further uncontrolled movement.
