Hammerlok

CM Hammerlok Coupling Link

A customer asks:

“Can a Hammerlok coupling link be used to repair hoist chain?”

Peter answers: Mechanical coupling links such as Hammerloks should not be used to join hoist load chain together. This presents a number of safety hazards to the operator and can cause possible damage to the hoist. Hoist load chain when damaged, worn, or when a longer reach is desired must be replaced with the proper length (one piece) from the original manufacturer.

Hoist chain cannot be repaired nor should a mechanical coupling link be used to repair broken links. If the hoist load chain broke due to an overload situation, a full breakdown and inspection of the hoist must be performed in accordance with ASME B30.16 and manufacturer’s guidelines.

Hi Martin,
Thanks for reaching out to us. Use of a chain other than genuine CM chain voids the warranty. We never recommend anything other than genuine CM chain.

You say “must be replaced with the proper length (one piece) from the original manufacturer.” But it has been stated by CM distributors that you can use Rudd chain in their hoists. Whilst I consider it to be inferior to CM chain in a number of ways it is sn alternative.
