- Flange mounted motor is a 230/460 volt 3 phase motor, 60 cycle, IP 541, 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 is spring set, electrically released for positive load control.
- Dual stage gearing, comprised of a worm or helical/worm and spur gears, make 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 gearcase, 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 bearings are self-aligning bearings with cast housing to maintain smooth drum rotation.
- Welded steel drum with outside flange anchors allow for uniform winding and help extend life of wire rope. Anchors allow cable to be over wound or under wound from either side of the drum.
- Extended steel drum shaft with both ends captured in fabricated steel frame for optimal strength and security.
