Procedures not specifically explained in this manual must be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM HOIST FAILURE: Do not use damaged equipment. If any defect or
damage is noted, have the problem corrected before further use.
Frequent Inspection
Perform the procedures in this section
BEFORE INTIAL USE and AT LEAST
MONTHLY. Inspection is needed more often
for heavily used hoists.
1)
Check operating mechanisms for proper
operation, proper adjustment, and unusual
sounds.
2)
Frequent Braking System Inspection
The braking system must automatically stop
and hold up to the rated load if the hand
chain is released.
3)
Frequent Hook inspection
a.
Distortion, such as bending, twisting, or
increased throat opening
b.
Wear
c.
Cracks, nicks, or gouges
d.
Latch engagement (if equipped)
e.
Damaged or malfunctioning latch (if
provided)
f.
Hook attachment and securing means.
4)
Frequent Hoist Load Chain Inspection
a. Test the hoist under load in lifting and
lowering directions and observe the
operation of the chain and sprockets. The
chain should feed smoothly into and way
from the sprockets.
b. If the chain binds, jumps, or is noisy, first
see that it is clean and properly lubricated.
If the trouble persists, inspect he chain
and mating parts for wear, distortion, or
other damage.
c. Examine visually for gouges, nicks, weld
spatter, corrosion, and distorted links.
Slacken the chain and move the adjacent
links to one side to inspect for wear at the
contact points. If wear is observed or if
stretching is suspected, the chain should be
measured as follows:

Inspection, Testing, and Maintenance

1) Select an unworn, unstretched length of
chain (e.g., at the slack end).
2) Suspend the chain vertically under
tension and, using a caliper-type gauge,
carefully measure the outside length of
any convenient number of links
approximately 12" to 24" overall.
3) Carefully measure the same number of
links in the used sections and calculate the
percentage increase in length.
4) If the used chain is 2.5% longer than the
unused chain, replace the chain.
5) Check rope or load chain reeving.
Periodic (Thorough) Inspection
A qualified technician should perform the
procedures in this section AT LEAST
YEARLY. Inspection is needed more often for
heavily used hoists.
1)
First follow all Frequent Inspection
procedures.
Additionally:
2)
Check fasteners for evidence of loosening.
3)
Check load blocks, suspension housings,
hand chain wheels chain attachments,
clevises, yokes, suspension bolts, shafts,
gears, bearings, pins, rollers, and locking and
clamping devices for evidence of wear,
corrosion, cracks, and distortion.
4)
Check hook retaining nuts or collars, and
pins, welds, or rivets used to secure the
retaining members for evidence of damage.
5)
Check load sprockets, idler sprockets, drums
and sheaves for evidence of damage and
wear.
