What should be done when the chain shows signs of wear at the bearing surfaces?

When a chain shows signs of wear at the bearing surfaces, the most appropriate action is to stop using the chain. This wear can compromise the integrity and safety of the lifting system. Continuing to use a worn chain can lead to failure during operation, posing significant risks not only to the equipment but also to the safety of personnel working nearby.

By stopping the use of the chain, you can prevent potential accidents and evaluate the extent of the wear. This pause allows for proper inspection and assessment of whether the chain can be repaired or needs complete replacement. The safety of the equipment and personnel should always take precedence, and identifying worn components is critical for maintaining operational safety standards.
