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.
Direct Drive Gear Reducer
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.
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 Drum Shaft
Captures both ends in a fabricated steel frame for optimal strength and security.
Wire Rope Assemblies
Sold separately per customer request.
AMSE B30.7 Compliance
Please contact the factory.
Two-Year Warranty
Industry-leading two-year “Move It With Confidence” limited warranty.
Vertical Lead Block
The Redline Series is used to change the direction of the rope, so the winch can be mounted in a convenient location and the Redline Lead Block will control the path of the rope to avoid obstacles, reduce hazard, and improve rope wear. Vertical Lead Block Series
