Load Chain Inspection
Load chain can become excessively worn, elongated and/or damaged beyond safe working condition.
A visual inspection of the load chain should be performed
BEFORE
each use of the hoist. The full
length of load chain must be replaced immediately if even one link is excessively worn, elongated or
damaged.

When measuring load chain dimensions, the use of Vernier calipers is required. Any load chain that
exceeds the maximum load chain 5 links dimensions, or less than the minimum load chain diameter
shown above must be immediately replaced with new load chain
BEFORE
being used/returned to
service.
Hook Inspection
When top and bottom hooks are overloaded they will stretch/open before failing. To prevent unit
failure, a visual inspection of both the top and bottom hooks should be performed
BEFORE
each use
of the hoist.
This inspection should involve checking for wear, reshaping, damage, corrosion, and hook stretch.
Any hook that is not in safe working order must be disposed of immediately and replaced with a new
hook.
