Ease of operation
If you compare our product with others, the handle force during operation is very small and work is easy because of its high-level mechanical efficiency. This winch is light and very convenient to carry for the compact design. Users can install the winch easily using the prescribed bolts. In addition, the each part is made by press work and the whole of winch is assembled with bolts, so it is easily disassembled. Anyone can repair and assemble this winch by just purchasing necessary replacing parts and installing them according to the instructions in the manual.

Outstanding durability
Ball bearings only from leading manufacturers are used for all bearings. The bearing allows smooth lifting and offers outstanding resistance against wear. Our unique profile shifted gear that performed special heat treatment is used for the gear reducer, and it allow you to work securely. The automatic brake has outstanding durability because it has the mechanism that can adjust the gap as desired. Baking finish performed on the surface is resistant to rust. It is strong and can be used in any location.

Reliable safety
Carefully selected materials as well as advanced design and technology provide the extremely high safety. We have enhanced the strength of the portions where load is intensively applied by combining a precision press-processing rib or double plate. A fail-safe mechanism is employed for the mechanical brake, so it never enters the state of no brake even if the impact is applied to a stopper arm. The method of anchoring the wire rope to the drums is a fail-safe structure with a special drum that an extra maintenance winding is maintained. Users can easily and surely anchor the end of a wire rope to the drum by using the attached hex wrench. The above features are all enabled thanks to our unique reliable safety design.
