When using the lifting chain should be noted that:

1. Check whether the lifting chain is intact and has cracks.

2. Lifting chain use should first test whether the chain can bear the weight.

3. When using the lifting chain should avoid contact with corrosive and strong oxidation of the material, so as to avoid the lifting chain by corrosive damage.

4. After using the lifting chain, remove dirt and impurities in time to keep the dry and clean degree of the chain.

5. Lifting chain idle when not used should be regularly coated with anti-rust oil so that the next time when the chain is not easy to rust and corrosion.

6. Lifting chain is strictly prohibited overload use, to ensure the normal service life of the chain.

Lifting chain is an indispensable part of the crane, the role of the crane is immeasurable, in the choice must pay attention to details, otherwise easy to cause serious consequences.
