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.
Remove or open access covers to
allow inspection of components.
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.
6. Check the brake mechanism for evidence
of worn, glazed, or oil contaminated friction
disks; worn pawls, cams, or ratchets; and
corroded, stretched, or broken pawl springs.
7. Check supporting structure or trolley,
if used, for evidence of damage.
8. Check warning label for legibility and replacement.
9. Check end connections of wire ropes or
load chains for evidence of wear, corrosion,
cracks, damage, and distortion.
10. Check the hoist and hoist mounting
lor evidence of missing parts.
WARNING! 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.
Storage Inspection
1. A hoist that is used in infrequent service,
which has been idle for a period of a month or more,
but less than a year, must be inspected
before being placed in service according to
the Frequent Inspection requirements.
2. A hoist that is used in infrequent service,
which has been idle for a period of a year or more,
must be inspected before being placed in service
according to the Periodic Inspection requirements.
Maintenance
1. Quarterly (every 3 months), clean off load chain,
then lubricate load chain links with lithium grease.
Apply grease to inner surfaces of load chain,
where the links rub against each other.
2. Repair or replacement of hoist components must be
performed only by a qualified technician using only
identical replacement parts with the same rating.
