Ingersoll-Rand SMB030 Chainsaw User Manual


 
MHD56391 - Edition 2 7
1. Fasteners. Check rivets, capscrews, nuts, cotter pins and
other fasteners on hooks and hoist body. Replace if missing
and tighten or secure 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.
3. Hooks. Inspect hooks for cracks. Use magnetic particle or
dye penetrant to check for cracks. Inspect hook retaining
parts. Tighten, repair or replace if necessary. Refer to the
latest edition of ASME B30.10 (Hooks) for additional hook
inspection information.
4. Chain Sheaves. Check for damage or excessive wear.
Replace if necessary.
5. Brake. Ensure proper operation. Brake must hold hoist rated
capacity. If load test indicates the need, disassemble. Brake
discs must be free of oil, any grease, unglazed and uniform in
thickness. Refer to “MAINTENANCE” section for allowable
brake disc wear. Check all other brake surfaces for wear,
deformation or foreign deposits. Inspect gear teeth, pawl and
pawl spring for damage. Check that brake pawl stops
counterclockwise rotation of ratchet gear. Clean and replace
damaged components as necessary.
6. Supporting Structure. If a permanent structure is used,
inspect for continued ability to support load.
7. Labels and Tags. Check for presence and legibility. Replace
if necessary.
8. End Anchor. Ensure end anchor is installed and unbent.
Replace if missing or damaged. Refer to “Attaching End of
Load Chain” in the “MAINTENANCE” section.
9. Load Chain. Measure the chain for stretching by measuring
across five link sections all along the chain length. Refer to
Dwg. MHP0041
on page 7. When any five links in the
working length reach or exceed the discard length shown in
Table 2, replace the entire chain. Always use a genuine
Ingersoll Rand replacement chain.

Hoists Not in Regular Use
1. Hoists which have been idle for a period of one month or
more, but less than one year should be given an inspection
conforming with the requirements of “Frequent Inspection”
before being placed in service.
2. Hoists which have been idle for a period of over one year
should be given a complete inspection conforming with the
requirements of “Periodic Inspection” before being placed in
service.
3. Standby hoists should be inspected at least semiannually in
accordance with the requirements of “Frequent Inspection”.
LUBRICATION
General
Thread lubricant or an antiseize compound use is recommended
for threaded shafts, capscrews and nuts. Unless otherwise stated,
remove old lubricant, clean the part with an acid free solvent and
apply a new coating of lubricant to the part before assembly.
Gears (38 and 41)
1. Remove nuts on gear cover.
2. Remove old grease and replace with new. For temperatures
-20° to 50° F (-29° to 10° C) use EP 1 grease or equivalent.
For temperatures 30° to 120° F (-1° to 49° C) use EP 2 grease
or equivalent.
Load Chain
WARNING
• Failure to maintain clean and well lubricated load chain may
result in chain failure causing injury, death or substantial
property damage.
1. Lubricate each link of the load chain weekly. Apply new
lubricant over existing layer.
2. In severe applications or corrosive environments, lubricate
more frequently than normal.
3. Lubricate hook and hook latch pivot points with the same
lubricant used on the load chain.
4. To remove rust or abrasive dust build-up, clean chain with
acid free solvent. After cleaning, lubricate the chain.
5. Use Ingersoll Rand LUBRI-LINK-GREEN®.
