Length over 11 links ( 11 t )
Replace load chain if any one of these dimensions exceeds maximum allowed wear.
Maximum allowed wear:
Minimum link diameter allowed (d): 0.1102” [2.8 mm]
Maximum pitch allowed (t): 0.3839” [9.75 mm]
Maximum length allowed (11t): 4.1063” [104.3 mm]
NOTICE:
If load chain needs replaced, then inspect chain guide and chain (load) wheel on hoist and
