Lifting chain for use with hooks

Date of release:2017-12-14 Author: Click:

Although we have been emphasizing energy conservation and emission reduction now, we must not waste if we can save. However, the lifting chain used with the hook is not recommended for mixing old and new. The main reasons are as follows:

1 The sprocket should be mounted on the shaft without skew and swing.

????In the same transmission assembly, the end faces of the two sprocket wheels should be in the same plane. When the center distance of the sprocket is below 0.5 m, the deviation is allowed to be 1 mm; when the center distance of the sprocket is 0.5 m or more, the deviation is allowed to be 2 mm.

????However, the side phenomenon of the friction sprocket tooth is not allowed, and if the two-wheel knitting is too large, the chain is easily broken and the wear is accelerated. Care must be taken to check and adjust the offset when changing the sprocket.

????2 The tightening of the lifting chain should be suitable, too tight to increase power consumption, the bearing is easy to wear; too loose chain is easy to jump and unchain.

????The degree of tightness of the chain is: lifted or pressed from the middle of the chain, and the center distance of the two sprockets is about 2% to 3%.

????3 The new lifting chain is too long or stretched after use. It is difficult to adjust. The chain link can be removed, but it must be even. The chain link should pass through the back of the chain, the locking piece should be inserted outside, and the opening of the locking piece should be in the opposite direction of rotation.

????4 After the sprocket wears seriously, the new sprocket and the new chain should be replaced at the same time to ensure good meshing. It is not possible to replace a new chain or a new sprocket alone.

????Failure to do so may result in poor engagement to accelerate the wear of the new or new sprocket. After the sprocket tooth surface wears to a certain extent, it should be turned over in time (refer to the sprocket used for the adjustable surface). To extend the use of time.

????5 The old lifting chain can't be mixed with some new chains, otherwise it will easily cause impact in the transmission and break the chain.

????6 lifting chain should remember to fill the lubricant in time. The lubricating oil must enter the mating clearance between the roller and the inner sleeve to improve working conditions to reduce wear.
