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.
