Lifting chain in use after a period of time should be regular cleaning, in the process of cleaning lifting chain, don't damage characteristics don't pay attention to in the process of cleaning, do not use corrosive liquid and make the chain hydrogen embrittlement, don't make the lifting chain temperature is too high, don't make the chain alloy metal elements precipitate or diffusion.

Check the lifting chain to ensure that the light is bright enough, each link should be checked, focus on looking for deformation, scratches, corrosion, wear inner ring.

Wear inspection of the contact points of each ring of the lifting chain can make the chain slack. If serious wear is found, relevant tools can be used for measurement. One is to choose a section of unused and frayed elongated chain; The second is to make the chain into a natural vertical state; The third is to measure the data of adding the worn chain and the unworn chain pitch, and calculate the proportion of the average distance increase of each chain link after wearing.
