Shell: Light aluminum alloy shell shall be adopted which is light but hard and fit for the use in the terrible work environment with a high heat dissipation rate and all tightness design.

Inverse phase sequence protecting device: It is the special electrial installation which control the circuit not to work in case of wiring error in the power supply.

Limit switch: The limit switch 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.

24V/36V device: It is used to prohibit the emergencies from occurring in case of the power leakage in switch.

Side magnetic braking device: This device shall realize the instant brake in case of the power dump.

Chain bag: It shell be light, handsome and durable.

Chain: The chain shall adopt the Japan FEC80 ultra heat-traetable steel alloy chain.
