Chain rigging is a combination of chains and rigging, and chains are an important component of chain rigging. The elongation of the chain in the chain rigging may be caused by the following reasons.
The chain rigging is overloaded for a long time to lift heavy objects, causing the chain of the chain rigging to elongate. Although it does not affect the use, the safety of the rigging cannot be guaranteed.
The quality of the chain in the chain rigging is poor, which leads to chain failure and elongation during use. We should choose high-quality chain slings, not just cheap ones.
Chain slings lift heavy objects at high altitudes for a long time, causing the chain to elongate. Chain slings cannot hang heavy objects at high altitudes for a long time, which is not safe.
After the chain is stretched, the use of the chain rigging should be immediately stopped and a new rigging should be replaced in a timely manner to ensure the safe completion of the lifting operation.
