INSPECTING THE LOAD CHAIN
The chain must be inspected at regular intervals, with a minimum
of once annually. As the frequency of use increases, the time
intervals between inspections must be reduced. During inspection,
the chain link must be examined along its entire length, including
the hidden parts. If the lifting equipment is frequently used with a
constant lifting distance, or in other words the switch from upward to
downward often takes place in the same area, a particularly thorough
inspection, and lubrication is required in that area. Worn chain can
also be an indication of worn hoist components. For this reason, the
hoist's chain guides, hook blocks and liftwheel (sprocket) should be
examined for wear and replaced as necessary when replacing chain.
1. Check to see if chain is dirty or poorly lubricated, see "Hoist
Lubrication", page 16.
2. Clean the chain with a non-caustic/non-acid-type solvent and
perform a link-by-link inspection for wear, or cracks, twisting or
deformation. Replace chain that shows any of these defects.

Criteria (mm)
Max: 41.8
a) Brake for evidence of slippage or rollback.
b) Control functions for proper operation.
c) Hooks for damage, cracks, twists, excessive throat opening, latch engagement, and latch operation,
see "Hook Removal Criteria", page 12.
d) Load chain for adequate lubrication, as well as for signs of wear, damaged links, or foreign matter, see
"Inspecting the Load Chain", page 13.
e) Load chain for proper reeving and twists.
a) All items listed for frequent inspections, see "Table 3: Minimum Frequent Inspections", page 13.
b) External evidence of loose screws, bolts, or nuts.
c) External evidence of worn, corroded, cracked, or distorted hook block, suspension screws, gears,
bearings, and dead end block.
d) External evidence of damage to lower hook assembly. Also check the upper suspension making sure
the retaining screw is present and tight.
e) External evidence of damage, or excessive wear of the liftwheel pockets. Widening and deepening of
the pockets may cause the chain to lift-up in the pocket, and result in binding between liftwheel, and
chain guides. Also check the chain guide for wear, or burring where the chain enters the hoist. Se-
verely worn, or damaged parts should be replaced.
f) External evidence of excessive wear of brake parts, see "Brake Cleaning and Replacement",
page 16.
g) Check the operation of the Remote Control making sure the buttons operate freely, and do not stick in
any position.
h) Inspect the Remote Control enclosure for damaged insulation.
i) Inspect suspension components for damage, cracks, wear, and operation. Also check hook retainer
screw and ensure it is properly torqued.
j) Inspect the loose end chain stop and bumper. Replace worn, or distorted parts.
k) Inspect the suspension lug, or hook for excess free play, or rotation. Replace worn parts as evidenced
by excess free play, or rotation.
l) Inspect for signs of lubricant leakage at the gearbox.

3. Slack the portion of the chain that normally passes over the lift-
wheel (sprocket). Examine the chain links for wear (see Fig. 9). If
the wire diameter anywhere on the link measures less than 90%
of the nominal wire diameter, replace the chain.
