Single lifting speed chain hoist:

Double lifting speed chain hoist:

Shell: made of light aluminum alloy, light and hard. The cooling fin is specially designed to ensure heat dissipation with the rate up to 40% and continuous service. The integral enclosed structure is applicable to place in chemical and electroplate factory.
Side magnetic braking device: The magnetic force generator is the latest design that is featured for generating magnetic force. It allows instant brake as soon as the electric power is cut off. Thus the braking safety while loading is guaranteed.
Limit switch: The limit switch device is installed where the weight is lifted on and off to make the motor stop automatically to prohibit the chains from exceeding for safety.
Chain: The chain imported FEC80 ultra heat-treatable aluminum alloy chain. It can be safely used in poor environments such as rain, seawater, and chemicals.
Hook: It is hot forged with perfect strength that it is hard to break. The operation safety of the lower hook is ensured by its 360 degrees rotation and safety tongue piece.
Support frame: The loading support frame consists of two steel plates, which are extremely sturdy.
Transformer:24v/36v transformer device .This device is used to prohibit unexpected accidents caused by electric leakage and guarantees safe use while raining
Electromagnetic contactor: Electromagnetic contactor can be used safely under high frequency.
Inverse phase sequence protecting device: It is the special electrical installation that controls the circuit not to work in case of wiring error in the power supply.
Push-button: waterproof push button is applied. It is light and durable.
