Designed around a totally enclosed, fan-cooled 3/4 HP motor that stands up to longer duty cycles. The WARN Works® 3000 ACI is a 3000-lb. rated pull winch powered by a 115/230V 50/60 HZ 1-Phase AC source, and a drum-style station switch that controls power in and out. It has an all-metal gear housing and three-stage planetary gear design with a 216:1 gear ration. The lever-actuated, sliding ring gear clutch allows for free spooling, and a mechanical braking system holds the full rated load. Great tool for fixed mount pulling situations. U.S.A.
