Lifting chain check safety points

　　Lifting the chain in the use of a period of time should be regularly cleaned, in the course of cleaning should not damage the lifting chain, the characteristics of the process should not pay attention to the clean, do not use corrosive liquid leaving the chain hydrogen embrittlement, Lifting chain temperature is too high, do not make the chain alloy metal element precipitation or diffusion.

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

　　Lifting chain of the ring contact point of the wear test can make the chain loose, if found serious wear and tear, you can use the relevant tools for measurement. One is to choose a section without the use of wear and elongated chain; the second is to make the chain into a natural vertical state; third is to measure the wear chain and the wear chain without adding the data to calculate the wear chain after the average The proportion of the chain link pitch increases.
