Inspection
1. Check hoist for oil leaks daily. Immediately repair
any leaks.
2. At the beginning of each shift operate the hoist in
both directions without a load. Ensure the motor
runs free, and that the brake(s) do not drag.
3. Keep hoist housings clean of dust and dirt build up
which may cause heat build up and sparks.
Inspection information is based in part on American
Standards of Mechanical Engineers Safety Codes
B30.16.

• All new or repaired equipment should be
inspected and tested by Ingersoll Rand
trained technicians to ensure safe
operation at rated specifications before
placing equipment in service.
• Never use a hoist that inspection
indicates is damaged.
Frequent and periodic inspections should be
performed on equipment in regular service. Frequent
inspections are visual examinations performed by
operators or
Ingersoll Rand
trained inspectors and
include observations made during routine equipment
operation. Periodic inspections are thorough
inspections conducted by
Ingersoll Rand
trained
technicians. ASME B30.16 states inspection intervals
depend upon the nature of the critical components of
the equipment and the severity of usage. Refer to
‘Inspection Classifications’ chart and ‘Maintenance
Intervals’ chart in Product Maintenance Information
Manual for recommended maintenance intervals.
Careful inspection on a regular basis will reveal
potentially dangerous conditions while still in the early
stages, allowing corrective action to be taken before
the condition becomes dangerous.
Deficiencies revealed through inspection, or noted
during operation, must be reported to designated
personnel to ensure corrective action is taken. A
determination as to whether a condition constitutes a
safety hazard(s) must be decided, and the correction of
noted safety hazard(s) accomplished and documented
by written report before placing the equipment in
service.
Frequent Inspection
On equipment in continuous service, a
shall be made by the operator at the
beginning of each shift and a ‘Quarterly Inspection’ (90
days) should be conducted during regular service for
any damage or evidence of malfunction.
Daily Inspection
Complete inspections prior to start of daily tasks.
Conduct visual inspections during regular operation for
indications of damage or evidence of malfunction (such
as abnormal noises).
1.
Lubricator:
Adjust air line lubricator drops during
hoist operation, refer to
section for requirements.
2.
Surrounding Area:
Visually check hoist for oil leaks.
Do not operate hoist if leaking oil is found. Ensure
surrounding area has no slippery surfaces and is
obstruction free.
3.
Hoses and Fittings:
Visually inspect for damage, air
leaks, and loose connections. Repair all leaks or
damage and tighten loose connections prior to
starting daily tasks.
4.
Hoist:
Check for visual signs or abnormal noises
(grinding, etc.) which could indicate a potential
problem. Make sure all controls function properly.
Check chain feed through hoist and bottom block. If
chain binds, jumps, is excessively noisy or “clicks,”
clean and lubricate chain. If problem persists,
replace chain. Do not operate hoist until all
problems have been corrected.
5.
Upper and Lower Limit Device:
Test operation with
no load slowly in both extremes of travel. Upward
travel must stop when chain stop on the bottom
block hits hoist limit switch. Downward travel must
stop when the chain stop attached to the end of the
unloaded load chain activates limit switch.
6.
Controls:
During operation of the hoist, verify that
response to pendant is quick and smooth. Ensure
controls return to neutral when released. If hoist
responds slowly or movement is unsatisfactory, do
not operate the hoist under load conditions until all
problems have been corrected.
7.
Brake:
During operation test brake. Brake must be
capable of supporting load without slipping. Brake
must stop the load when control returns to neutral.
If brake does not hold load or does not stop the load
properly, brake must be further inspected.

• Worn or improperly functioning
brakes may cause excessive heat
build up and sparks.
8.
Hooks:
Check for wear or damage, increased throat
width, bent shank or twisting of the hook. Replace if
hook latch snaps past tip of hook. Check hooks
swivel freely. Replace hooks which exceed the
throat opening. Refer to
. Replace
hooks which exceed a 10° twist. Refer to
. If hook latch snaps past tip of hook, the hook
is sprung and must be replaced. Refer to the latest
edition of ASME B30.10 ‘HOOKS‘ for additional
information. Check hook support bearings for
lubrication or damage. Ensure that they swivel
easily and smoothly. Refer to Product Maintenance
Information Manual.
9.
Hook Latch:
Make sure hook latch is present and
not damaged. Replace if necessary.
