3.
UPPER AND LOWER LIMIT DEVICE. Test operation
with no load slowly to both extremes of travel. Upward
travel must stop when the bottom block or stop ring on
chain hits hoist limit arm. Downward travel must stop when
the loop at the unloaded end of the chain decreases and
activates the limit arm.
4.
AIR SYSTEM. Visually inspect all connections, fittings,
hoses and components for indication of air leaks. Repair
any leaks found. Check and clean the filter in the inlet stud
(24) and the inlet strainer (24C) if equipped.
5.
CONTROLS. During operation of hoist, verify response to
pendant, or pull chain, is quick and smooth. Ensure that the
controls return to neutral and hoist operation stops when
released. If hoist responds slowly or movement is
unsatisfactory, do not operate hoist until all problems have
been corrected.
6.
HOOK LATCH. Make sure the hook latch or gate is
present and operating. Replace if necessary.
CAUTION
• Do not use hoist if hook latch or gate is missing or damaged.
7.
LOAD CHAIN. Examine each link for bending, cracks in
weld areas or shoulders, traverse nicks and gouges, weld
splatter, corrosion pits, striation (minute parallel lines) and
chain wear, including bearing surfaces between chain links
(refer to Dwg. MHP0102). Replace a chain that fails any of
the inspections. Check chain lubrication and lubricate if
necessary. Refer to ‘Load Chain’ in “LUBRICATION”
section.
CAUTION
• The full extent of load chain wear cannot be determined by
visual inspection. At any indication of load chain wear
inspect chain and chain wheel in accordance with
instructions in ‘Load Chain’ listed in “Periodic Inspection”
section.
8.
LOAD CHAIN REEVING. Ensure welds on standing links
are away from the powered chain wheel. Reinstall chain if
necessary. On hoists with multiple chain falls, make sure
load chain is not capsized, twisted or kinked. Adjust as
required.
Periodic Inspection
Frequency of periodic inspection depends on the severity of
usage:
NORMAL
HEAVY
SEVERE
yearly
semiannually
quarterly
Disassembly may be required for HEAVY or SEVERE usage.
Keep accumulative written records of periodic inspections to
provide a basis for continuing evaluation.
Inspect all the items in "Frequent Inspection". Also inspect the
following:
1.
FASTENERS. Check all rivets, split pins, capscrews and
nuts. Replace if missing or tighten if loose.
2.
ALL COMPONENTS. Inspect for wear, damage,
distortion, deformation and cleanliness. If external evidence
indicates the need, disassemble. Check gears, shafts,
bearings, sheaves, chain guides, springs and covers.
Replace worn or damaged parts. Clean, lubricate and
reassemble.
