Chain Wear Test

Chain wear test is a measurement of wear of the chain links and pins. Do the steps that follow to check chain wear.

1. Lift the mast and carriage enough to put tension on the lift chains.

2. Measure precisely ten links of chain distance at the center of pins in millimeter.

A chain wear gauge can also be used.

3. Calculate chain wear rate.
