Maintenance of lifting chain
1. The tightness of the lifting chain should be appropriate, too tight will increase power consumption, and the bearing will be easy to wear; The tightness of the chain is: lifted or pressed from the middle of the chain, the center distance of the two sprockets is about 2%-3%.
2. The new hoisting chain is too long or stretched after use, making it difficult to adjust. The chain links can be removed depending on the situation, but it must be an even number. The links should pass through the back of the chain with the cleats inserted outside, and the openings of the cleats should face the opposite direction of rotation.
3. After the sprocket is seriously worn, the new sprocket and new chain should be replaced at the same time to ensure good meshing. You can't just replace a new chain or a new sprocket alone. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or the new sprocket. After the sprocket tooth surface is worn to a certain extent, it should be turned over and used in time (referring to the sprocket used for the adjustable surface). to extend the usage time.
4. The old hoisting chain cannot be mixed with part of the new chain, otherwise it is easy to produce impact in the transmission and break the chain.
5. Remember to add lubricating oil to the lifting chain in time during work. The lubricating oil must enter the matching clearance of the roller and the inner sleeve in order to improve the working conditions and reduce wear.
