As we all know, food and medicine have a shelf life, and food and medicine that have passed the shelf life must be discarded. But what many people don't know is that lifting rigging chains actually have a shelf life. So, how long is the shelf life of chains in general? Do chains that have passed the shelf life need to be discarded?
In the long-term use, the lifting chain will gradually be worn out due to the normal work. After a certain period of time, these accumulated wear and tear will cause the chain to be completely scrapped. The shelf life of the chain is generally 3 to 5 years, but the chain used by many people is often damaged before the service life. This is because these people misused the chain and caused the chain to be damaged. It may also be because they did not store the chain properly and caused the chain to be severely rusted. After the chain reaches the shelf life, the degree of wear and oxidation has basically reached the level of disallowed use. If it is used forcibly, it will only cause accidents.
The shelf life of lifting rigging chains is the result of scientific experiments by professional researchers. Users need to know the service life of the chain. Never use an "expired" chain to continue operations.
