Lifting chain is an essential and important device for the crane. It can adjust the length of chain according to the lifting height of the crane, which plays an important role in improving the efficiency of crane operation and expanding the scope of crane operation.

In the same kind of products, the chain product series are divided according to the basic structure of the chain, i.e. the shape of components, the parts and parts meshed with the chain, the size proportion between parts, etc

1. After the sprocket wheel is seriously worn, replace it with a new sprocket wheel and a new chain at the same time to ensure good engagement. It is not allowed to replace the new chain or sprocket wheel alone. Otherwise, it will cause poor engagement and accelerate the wear of new chain or new sprocket wheel. When the tooth surface of sprocket wheel is worn to a certain extent, it shall be turned over for use in time (it refers to the sprocket wheel used for adjustable surface). To extend the use time.

2. The old lifting chain cannot be mixed with some new chains, otherwise it is easy to have impact in the transmission and pull the chain off.

3. During the operation of lifting chain, please remember to add lubricating oil in time. The lubricating oil must enter into the fitting clearance between the roller and the inner sleeve in order to improve the working conditions and reduce the wear.
