HHBB electric chain hoist is a kind of popular electric hoist and HHBB electric chain hoist has a lot of advantages as below:

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 which 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 swith device is installed where the weight is lifted on and off to make the motor to stop automatically so as 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 environment such as rain,sea water and chemicals.

Hook:It is hot forged with perfect strength that it is hard to break.The operation safety of the lower hok is ensured by its 360 degrees rotation and safety tongue piece.

Support frame:The loading support frame consists of two steel plates,which is extremely sturdy.

Transformer:24v/36v transformer device .This device is used to prohibit unexpected accidents caused by electric leakage and guarantees the safe use while raining

Electromagnetic contactor:Electromagnetic contactor can be used safely under high frquency.

Inverse phase sequence protecting device:It is the special electrical installation which 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.
