The JK fast winch is powered by a three box asynchronous motor, driven by an elastic coupling, a three-stage enclosed gear reducer, and a tooth embedded coupling to drive the drum, using electromagnetic braking. This product has high universality, compact structure, small volume, light weight, and convenient transfer. It is widely used in material lifting or towing in construction, water conservancy engineering, docks, and related equipment of modern electronic control automatic operation lines.

The traction speed of the wire rope of the fast winch is 30-40m/min, and the single rope traction force without the labor-saving pulley group is about 5-80kn. There are two types: single drum and double drum. In construction, vertical transportation equipment is often equipped with gantry frames, cross frames, and pulley blocks.
