Fetures:

Flange Mounted Motor - 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.
Load Holding Motor Disc Brake - Brake is spring set, electrically released for positive load control.
Dual Stage Gearing - Gearing is comprised of a worm or helical/worm and spur gears, making winches well suited for applications requiring secure load control and accurate positioning. The heat-treated worm or 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. Guarded, heat treated spur gearing provides secondary reduction. Grease zerks allow for easy lubrication.
Flange Style Roller Bearing - Bearings are self-aligning with cast housing to maintain smooth drum rotation.
Welded Steel Drum - 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.
Extended Steel Drume Shaft - Captures both ends in a fabricated steel frame for optimal strength and security.
Wire Rope Assemblies - Sold separately per customer request.
Two Year Warranty - Industry-leading two-year Move It With Confidence limited warranty
