Chain Inspection: Hoist Chain vs. Rigging Chain

Hoisting & Lifting Equipment | Rigging | Inspection & Maintenance | By Perry Bishop | Nov 02, 2016


We recently received the following question on chain inspection from Slade, a utility crew supervisor working for a water district:

“I was wondering if you carry a “no-go gauge” for Columbus McKinnon chain to inspect gouges, nicks and stretching on the links. Our warehouse personnel struggle to determine the correct gauge for your chain.”

Perry Bishop, our technical trainer, answers: 

We receive this question on chain inspection often, so we thought it would be worthwhile to write a blog to explain the gauges we offer and identify which gauge is the most suitable for the type of chain in question.

For our electric, pneumatic, hand chain hoists and lever tools, we have the following go/no-go gauge:

Go/no-go gauge for CM’s hoist load chain

It is made for CM’s load chain only, such as Star and Disc Grade, and should only be used to measure that style of chain. You can purchase this gauge from your local CMCO distributor under the part #3191.

To find a distributor in your area, simply visit www.cmworks.com and click on the “Find a Distributor” button on the right-hand side of the page.

For our Herc-alloy 800 & 1000 rigging chain (alloy chain slings only) we have the following wear limit rigging chain gauge, part #CWGC.  It is used to check below the hook chain such as HA-800 and HA-1000.

A common mistake that happens quite frequently in our industry is that individuals use the wrong gauge on the wrong type of chain. Always ensure you are using the correct gauge and follow instructions on the gauges for proper measuring techniques.
