tance from the first pin counted to
the last pin counted in a span while
the chains are lifting a small load.

tance from the first pin counted to

the chains are lifting a small load.
3. (SPAN) The number of pins in the
length (segment) of chain to be

4. (PITCH) The distance from the

All chains must be replaced if any link has wear of 3% or more, or if

Replace all chains as a set. Do not remove factory lubrication or
paint new chains. Replace anchor pins and worn or broken anchors
when installing new chains. Adjust tension on new chains. Lubricate
chains when they are installed on the upright.
