  Detailed description


As emergency overload protection, Clutch will work and motor will stop when abnormal load

Cooling fan

Cooling fan prevents motor over heat when continuous long time usage. Hollowed-out fan cover and cooling fin not only enhance fan heat dissipation capacity but also makes fan operate more quietly.

Limit switch without guide frame

No guide frame ensures hoist lift and drag the weight diagonally.

The shell

Except for connecting case, all other parts hoist body adopt aluminum with light weight but exceptional rigidity, as well as high dust-protection and water-protection

Side magnetic braking device

The magnetic force generator is the latest design which is featured for generating magnetic force. It allows instant brake as soon as the electric power is cut off. thus brakes safety while loading is guaranteed.

Dual speeds hoist adopt built-in inverter

Adopting built-in inverter to make hoist in dual speeds reduces swing in operation, helps hoist start steadily and stop slowly. The speed ratio can be adjusted, the standard speed ratio is 4:1, if for special requirement, please inform in advance

Antiphase protector

Advantages: When power-supply wiring mistake, the control circuit is unable to move in order to protect motor from being burned.


It is hot forging with perfect strength that is hard to break. The operation safety of the lower hook is ensured by its 360 degrees rotation and safety tongue piece


High grade: It is import Japanese chain with ultra strong heat treatment alloy steel.
Advantages: It is safely when used in the rain water, sea water, under the chemical and other bad conditions
