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

2.INVERSE PHASE SEQUENCE PROTECTING DEVICE:it is the speaicl electircal installation which control the circuit not to the work in case of wiring errorin the power supply.

3.LIMIT SWITCH:the limit switch device is installed where the weightis lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety. 

4.24V/36V DEVICE:It is used to prohibit the emergencies from occurring in case of the leakage in the switch.

SIDE MAGNETIC BRAKING DEVICE: This device shall realize the instant brake in case of power dump.

CHAIN BAG:It shall be light.handsome and durable.

5.CHAIN:The chain shall adopt the imported FEC80ultra headtreable aluminum alloy chain

Product features and advantages:

Our hoist is made of high-strength alloy,consists of beautiful appearance,compact mechanism,small in size and light weight.

And we use double-geared drive,helical gear drive when it works under fast speed so that the hoists can drive smoothly with low noise.

Details of products:

 1.Side magnetic braking device
This masterly structure ensure the hoist absolutly safty when the power off. And ensures it is safe when has excess load. Also it combine to the motor braking as the double brake system to strengthen security and durability

 2. The Gear
The gear made of alloy steel and through the heat treatment

 3.Electric motor partial outer cover
strength aluminum shell through compression casting formation. 
Features: Solid and light, Fast release heat, Continuous use, Enclosed structure. Can be used in the chemical plants, electroplating factories

 4. The Hooks
They are made by hot forging and heat treatment

 5. The Chain
It is made of FEC80 ultra strong heat treatment alloy steel. 
Advatages: It is safely approximately when used in the rain water, the sea water, under the chemical and other bad conditions

 6. TheAntiphase protector
Advatages: When power-supply wiring mistake, the control circuit is unable to move
