The operator shall perform a pre-use inspection,
if any deficiencies are found the equipment will be taken out
of service and the supervisor notified.
||Visually inspect all load chains for gross damage
that may be a hazard.
||Hoist is properly secured.
||The load does not exceed the load limit on the warning label.
||Check that motions are smooth and regular with no hesitations, vibration,
binding, unusual noise, or other irregularity.
||Chain is not kinked or damaged.
The Annual inspection may be performed with
the hoist in its normal location and do not require the hoist to be
dismantled. Covers and other items normally supplied to allow inspection
of components should be opened or removed for these inspections.
||Operating mechanisms checked for maladjustment
and listened to for unusual sounds that may indicate problems.
||Tightness of bolts, nuts, and rivets.
||Excessive wear, corrosion, cracks,
or distorted parts in the following:
- load blocks
- suspension housings
- hand chain wheels
- chain attachments
- suspension bolts
- locking and clamping devices
||Damage or excessive wear on hook-retaining
nuts or collars and pins and welds or rivets used to secure the
||Excessive wear or damage on load sprockets,
idler sprockets, hand chain wheel, and drums or sheaves shall be
checked for damage or excessive wear.
||Hand chain-operated hoists checked
for evidence of worn, glazed, or oil-contaminated friction disks;
worn pawls, cams, or ratchets; and corroded, stretched, or broken
pawl springs in braking mechanism.
||Evidence of damage to supporting structure
||Presence of legible warning labels
||End connections load chains shall be
checked for evidence of wear, corrosion, cracks, damage, or distortion.
||Welded link hoist chain
||The hoist shall be tested under load
in lifting and lowering directions and the operation of the chain
and sprockets shall be observed. The chain should feed smoothly
into and away from the sprockets.
||If the chain binds, jumps, or is noisy,
it shall first be checked to ensure that it is clean and properly
lubricated. If the trouble persists, the chain and mating parts
shall be inspected for wear, distortion, or other damage.
||The chain shall be examined visually
for gouges, nicks, weld spatter, corrosion, and distorted links.
||The chain shall then be slackened and
the adjacent links moved to one side to inspect for wear at the
||The chain should be measured according
to the hoist manufacturer's instructions. If instructions are not
available, the process shall continue as follows.
- An unworn, unstretched length
of the chain shall be selected (e.g., at the slack end).
- The chain shall be suspended
vertically under tension and, using a calliper-type gage,
the outside length of any convenient number of links shall
be measured (approximately 12 to 24 inches overall).
- The same number of links in the
used sections shall be measured and the percentage increase
in length shall be calculated.
||Cracks, nicks, or gouges.
||Latch engagement, damaged or malfunctioning
latch (if provided) .
||Hook attachment and securing means.
||Deformation. Any bending or twisting
exceeding 10 degrees from the plane of the unbent hook.
||Throat Opening. Any distortion causing
an increase in throat opening exceeding 15 percent.
||Wear. Any wear exceeding 10 percent
of the original section dimension of the hook or its load pin.
