Abstract
A hoist rotation limiting system for a hoist. A hoist drum has a grooved exterior surface configured to position a cable in a predetermined position relative to the ends and longitudinal axis of the hoist drum as the cable is wound onto or off of the hoist drum. Upon the cable being positioned in the predetermined position, the cable urges portions of a carrier weldment to contact a switch, thereby sending an electrical signal to stop rotation of a hoist motor.
