A hoist SHALL NEVER be used if the load chain shows any evidence of mechanical damage or
excessive wear. Never use the load chain as a sling. Use only original equipment chain as
supplied by a factory authorized source. Improper load chain storage or installation can render
the load chain unusable prior to the first lift.
6.7.1
Load Chain Inspection
The hoist operator SHALL perform a visual inspection prior to first daily use. This inspection shall include
the following:
1. Wear or cracks of the links
2. Twisted or deformed load chain
3. Dirty or poor lubrication of load chain
A qualified person SHALL be designated to routinely conduct an in-depth inspection of load chain (See
Section 7 – Preventative Maintenance for schedule recommendations). This designated person SHALL
inspect load chain using good judgment in evaluating the remaining service life. Any deterioration of load
chain resulting in appreciable loss of original strength SHALL be noted and evaluated.
An in-depth inspection SHALL include a written record that is dated and signed by the inspector.
NOTICE
If load chain needs replaced, then inspect the chain guide and chain sprocket on hoist and idler
sprocket in 2-fall load block (if supplied) for excessive wear. A chain sprocket showing evidence
of scored pockets or sharp edges generated from wear SHALL be replaced. A worn chain
sprocket or idler sprocket can greatly reduce the life of load chain.
