The lifting chain must be adjusted for tightness before use. If the chain is too loose and cannot be lifted smoothly, if the chain is too tight, it will aggravate the wear of the chain. How is the most suitable adjustment for the chain?
The adjustment of the lifting chain has a range. Generally, the tightness of the lifting chain is when the chain is pressed down or lifted, and the center distance between the two sprockets is best between 2% and 3%. The chain is adjusted to this range, and it can be smoothly lifted and pulled during use without severe wear and tear, reducing chain loss and prolonging the use time.
The lifting chain must be prepared with tools before use, and standardize operations to reduce damage and improve work efficiency.
