To check the wear, the length of eleven chain links is measured. Depending on the calliper used and the chain hoist, this can be measured directly or in three stages.

   Raise a lightweight load slightly to tension the chain.

Measuring directly:

   Measure the length ‘l’ over 11 chain links of the chain (from outer edge to outer edge).

   Compare the measured value with the table (see page 32). The measured value should not exceed the maximum ‘l’.

   Measure again at several points and compare them.

   If the length exceeds the specified value, the chain has been stretched too much through operation. Exchange the chain and chain sprocket. See page 42.

Measure in steps:

   Measure 3 chain links from outside to outside ‘l1’.

   Measure 5 chain links from inside to inside ‘l2’. When doing so, do not measure the five chain links completely from inside to inside, but only place the calliper on the respectively next chain link.

   Measure 3 chain links from outside to outside ‘l3’.

   Add the measured values together.

   Compare the measured value with the table. The measured value should not exceed the maximum ‘l’.

   Measure again at several points and compare them.

   If the length exceeds the specified value, the chain has been stretched too much through operation. Exchange the chain and chain sprocket. See page 42.
