Thern 4BP Series Heavy Duty Electric Power Winches

Model 4bp heavy-duty electric power winches

All Thern winches and cranes are sold without wire rope.

4BP SERIES

31,000 to 51,000 lb Capacity 

The 4BP Series of heavy-duty electric power winches (31,000 to 51,000 pounds) is designed for a wide range of applications including barge and rail car positioning, bulk material handling, and much more. The range of options in lifting capacity, motor power and drum width enable a 4BP winch to be implemented within a relatively small footprint while retaining a high load rating and wire rope capacity. Fixed or variable speed controls may be mounted directly on the winch, minimizing footprint and allowing precise control of the winch.
