The lifting chain is flexible, the breaking force is large, the wear degree is small during use, and the lifting chain is corrosion-resistant and reliable with the sprocket. The inspection of the lifting chain is easier, and the 80-grade galvanized lifting chain can be easily and quickly inspected with the help of fixed diameter or wear measurement provisions, unlike the steel wire rope which cannot judge the internal broken wire. In the use of wire rope, it is easy to appear rope strand loosening and rope core leakage, and it is impossible to judge the internal broken wire. Therefore, the use of lifting chain safety factor is higher, relatively speaking, but also more used and extensive.

　　Lifting chain in the process of use and other lifting tools, after reaching a certain degree will be scrapped. Lijia heavy summed up the lifting chain of 5 scrap standards:

　　1, the link is broken, do not continue to work;

　　2. If the ring is deformed, please stop working immediately and replace the part in time.

　　3, the chain ring is seriously worn, please understand the replacement;

　　4, there is serious deformation between the chains;

　　5, the hook is seriously deformed, and the degree of deformation exceeds 10% of the original, please replace it immediately to avoid dangerous events.

　　Please keep in mind the above standards, if you find one of them, please replace it in time.
