Depending on the lifting height of the lifting object, the length of the chain can be adjusted to complete the lifting and transportation operation. The galvanized chain is an indispensable and important part of the crane. The Leaf Chain manufacturer shares how to adjust and maintain it during use. What about regalvanized chains?
1. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is below 0.5 meters, the allowable deviation is 1 mm. When the center distance of the sprocket is above 0.5 meters, the allowable deviation is 2 mm. However, friction sprocket tooth side phenomenon is not allowed. If the two wheels are moved too much, it is easy to produce off-chain and accelerated wear. When replacing the sprocket, care must be taken to check and adjust the offset.
2. The tightness of the lifting galvanized chain should be suitable, too tight to increase power consumption, the bearing is easy to wear and the loose chain is easy to jump and off the chain. The tightness of the chain is: lifted or pressed from the middle of the chain, the center distance between the two sprockets is about 2%-3%.
3. After the sprocket wears seriously, the new sprocket and new chain should be replaced at the same time to ensure good meshing. It is not possible to replace new chains or sprockets alone. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or new sprocket.
Lifting galvanized chain is of special significance to improve the operating efficiency of the crane and expand the operating range of the crane, and the service life of the product can be extended by adjusting and improving the working conditions.
