Electric Chain Hoist

Electric chain hoist is a small light lifting equipment. It consists of electric motor, transmission, and chains. Compared with the electric hoist, the chain hoist adopts chains to replace the wire ropes. Its elevating capacity ranges from 0.5 tons to 60 tons, and the lifting height is 3 to 120 meters.

In comparison with chain block, electric chain hoist has the advantages of light weight and convenience. Furthermore, it also improve the demerits of relying on manual work and poor lifting speed of the chain block. In a word, electric chain hoist is a perfect combination of electric hoist and chain block. It employs the disc brake motor as the retarder of cycloid pin. All of this makes the electric chain hoist a efficient, convenient, reliable, compact, small and light lifting equipment.

Electric chain hoist applies to elevating weight, loading or unloading goods, maintaining equipment. It’s advanced structure, small size, light weight, reliable performance make it popular in kinds of working places. Electric chain hoist can be installed on I beam, curve track, cantilever, guide rail or other designated areas.

The speed of the electric chain hoist is various: double speed, single speed, variable frequency starting, two-speed variable frequency starting. The control voltage of the chain hoist is 24V/26V. It can energize with supply voltage 110V-690V, and the normal voltage standard is 380V/50HZ. Limit switch and over voltage protection should be equipped on the machine.

Installation method
First, install the chain box. Then cut the power before you connect the power line, and be sure that the ground electrode works well. If not, the operator would have a electric shock. Next, lubricate the loading chain of the hoist. Because the lubrication is a key factor of the service lift of the chain. We should lubricate the chains timely and effectively to prolong the working life. After that, check out the arrangement of the chains. Make sure the chains are arranged in good order. Don’t load anything if the chains twine together. At last, check out the working voltage. Because the voltage is set in accordance with the customer’s need, we should recheck whether the voltage is suitable or not, and we can regulate the voltage by reading the specification.
