This winch has 2 drums that rotate the same direction at the same time with several special wire rope grooves and 2 pressure rollers attached on each drum. It provides a stable pulling power in both directions and prevents loosing the wire rope with only one main body. This winch is effective in pulling left and right directions on a horizontal plane. It is also possible to pull in one direction such as towing because the synergistic effect of the drum with special wire grooves and pressure rollers provide a firm grip on the wire rope. It is small and lightweight so it can be used in various locations.
