MRO ISSUES
checklists are general guides, and not
all-inclusive. The key words are clean
and operational. Pulleys or idlers that
have material build-up on them will
cause tracking problems. The same can
be said for pulleys with uneven lagging
wear. Belt-cleaning devices or systems,
plows, and self-aligning idlers must be
operational to perform their tasks. Belt
damage, pulley damage, and tracking
problems will result if these accessory
components are not maintained.
Shut-Down-Conveyor-Inspection
Checklist. A typical maintenanceinspection walk-through of a shut-down
conveyor should include, but not be
limited to, the following 19 items:
1. Perform the lockout/tagout (LOTO)
verification procedure.
2. Identify safety hazards.
3. Complete belt inspection.
4. Inspect head pulley and/or drive
pulley for damage, cleanliness, and
worn lagging.
5. Inspect for proper lubrication of
bearings and mechanical devices.
6. Inspect for the presence of material
build-up and trapped material.
7. Inspect skirting in the loading
area for proper adjustment and
condition.
8. Inspect impact/slider bed or impact
idler for damage and cleanliness.
9. Inspect return- and carrying-side
idlers for damage, cleanliness, and
free-turning.
10. Inspect all self-aligning idlers,
both carrying- and return-side to
ensure they are capable of operating
(actuating from belt friction) and
not tied off.
11. Inspect for cleanliness of primary
and secondary loading station.
12. Inspect trippers to ensure they are
clean and operational.
13. Inspect structure/frame for integrity
and alignment.
14. Inspect tail-pulley condition.
15. Inspect head-pulley cleaner to
ensure it is operational.
16. Inspect head, bend, and snub-pulley
condition.
17. Inspect the clean and operating
take-up.
18. Ensure plow (V-guide or angle) is
operational.

19. Ensure all bearings are clean and

capable of operating.
Once inspection of the shut-down
conveyor is completed, confirm that
all personnel, tools, and equipment
are clear of the system and accounted
for to avoid injuries or damage to the
equipment when it is restarted. Next,
energize the system and let it run empty
to ensure proper belt tracking. Perform

another visual walk-through and listen
carefully to make sure there are no
unusual noises, which could indicate
idler or bearing failure or rubbing of
the belt against the conveyor structure.
Be sure the belt is running reasonably
well before introducing a load and
conducting the next inspection. Note
that empty and loaded conveyor systems
may track differently. Furthermore,
