The double-drum hand-cranked friction winch is a manual transport tool used in the mountain areas and can also be understood as a hand-cranked cableway. By manually cranking the rope, it facilitates the reciprocating movement needed to transport materials up the mountain.

1. It is designed with a hand crank and reel straight chain, no reduction gearbox, 1:1 speed and equipped with a torsion spring bi-directional mechanical brake.
2. The product adopts torsion spring two-way mechanical brake, which can brake quickly to ensure the safety during transport and reduce the occurrence of accidents.
3. Weight of product is only about 13kg, which is compact and easy to carry, suitable for long-distance traction use in the field.
4. The product is designed with a 1:1 speed ratio, eliminating the need for speed reducer. By manually cranking the rope for reciprocating motion, materials can be quickly transported up the mountain, thereby improving work efficiency.
