Measuring Chain Links: What are the Considerations for Wear?

Entertainment | Rigging | by Nick Fleming | Nov 15, 2018


Q-A-chat.jpg

John, a steel fabricator out of Connecticut, asked the following question during our recent safety webinar:

“When measuring links, are there any additional considerations for inspection and wear as it relates to the area around the embossing of the trace codes?”

Nick Fleming, CM Entertainment Business Development Specialist, answers:

First, thank you for asking the question during our recent safety webinar. We always appreciate those who take the time to seek clarification rather than guessing at a possible solution.

Although it may seem that the area containing Columbus McKinnon’s trace codes and other embossed identification marks may need additional attention or measurement, it actually follows the same parameters as any other section of chain. The embossed areas of a chain are strategically located on the chain links so that no additional consideration is required beyond normal inspection procedures.

So, if you find an embossed area that you suspect has wear or damage, simply follow the same inspection and measuring techniques as you would on any other portion of the chain. If the embossed area is no longer legible, that is indication enough for retirement of the chain. Of course, if you find a mark on your chain in any location that you are not comfortable making the call on yourself, you may always reach out to your local certified warranty center or contact your CM-ET representative and they can help you get the clarification you need.

I hope this answers your question. If you need any additional information, feel free to reach out to me directly.
