FEATURES

Motor is a 230 or 460 volt, 3 phase motor, 60 cycle, IP 54*, TEFC severe duty, reversible, class B or F insulated, continuous duty brake motor. Standard motors comply with relevant standards including NEMA, MG1, ANSI, CSA, IEC1 and ABS.

Brake is spring set, electrically released for positive load control.

Reducer is comprised of helical/worm gears and delivers lower efficiencies from 65% to 76% making winches well suited or applications requiring secure load control and accurate positioning. The heat-treated helical/worm gear set provides improved durability and operates in an oil bath, enclosed in a high strength cast iron gear case, SAE class 30. Double lip oil seals keep oil in and contaminants out. Large capacity bearings ensure long life. Speed reducers meet AGMA standards.

Bearings are self-aligning with cast housing to maintain smooth drum rotation.

Drum has outside flange anchors, which allow for uniform winding and helps to extend life of wire rope. Anchors allow cable to be over wound or under wound from either side of the drum.

Captures both ends in a fabricated steel frame for optimal strength and security.

Sold separately per customer request.

Industry-leading two-year “Move It With Confidence” limited warranty.
