24. Never use the hoist for lifting or lowering people, and never allow anyone to stand on a
suspended load.
25. Do not use a cheater bar or extender handle.
26. Do not swing a suspended load.
27. Never weld or cut on a load suspended by the hoist.
28. Never use the hoist chain as a welding electrode.
29. Do not operate hoist if chain jumping, excessive noise, jamming, overloading, or binding
occurs.
30. Only operate the hoist with manual power.
31. After use, or when in a non-operational mode the chain hoist should be secured against
unauthorized and unwarranted use.
32. Do not leave a load suspended when the hoist is unattended or not in use.
1. Always store the hoist in a no load condition.
2. Wipe off all dirt and water and hang in a dry place.
3. Oil the chain, hook pins and hook latch pins.
4. Before returning hoist to service follow instructions for 'Hoists not in Regular Service' in the
Frequent and periodic inspections should be performed on equipment in regular service.
Frequent inspections are visual examinations performed by operators or service personnel
during routine hoist operation. Periodic inspections are thorough inspections performed by
personnel trained in inspection and maintenance of the hoist. 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 an
appointed person. A determination must be made as to whether a deficiency constitutes a safety
hazard before resuming operation of the hoist.
Records and Reports
Some form of inspection record should be maintained for each hoist, listing all points requiring
periodic inspection. A written report should be made monthly on the condition of the critical
parts of each hoist. These reports should be dated, signed by the person who performed the
inspection, and kept on file where they are readily available for review.
Frequent Inspection
On a hoist in continuous service, frequent inspection should be made at the beginning of each
shift. In addition, visual inspections should be conducted during regular service for any damage
or evidence of malfunction.
1. OPERATION. Check for visual or abnormal noises which could indicate a potential problem.
Do not operate a hoist unless the load chain feeds through the hoist and hook block
smoothly. Listen for "clicking", binding or malfunctioning. The clicking sound of the pawl on
the ratchet gear is normal when a load is being raised. If chain binds, jumps, or is
excessively noisy, clean and lubricate the chain. If problem persists, return the hoist to your
nearest repair center. Do not operate the hoist until all problems have been corrected. Check
that hand chain moves freely and without binding or excessive drag. Hook should stop
moving when hand chain stops moving.
2. HOOK LATCH. Check operation of the hook latch. Replace if broken or missing.
3. HOOKS. Check for wear or damage, increased throat width, bent shank or twisting of hook.
Replace hooks which exceed the throat opening discard width (15%) shown in Table 1 (ref.
Dwg. H-01) or exceed a 10° twist (ref. Dwg. H-01). If the hook latch snaps past the tip of the
hook, the hook is sprung and must be replaced. Check hooks swivel easily and smoothly.
Repair or lubricate as necessary.
4. CHAIN (ref. Dwg. C-01). Examine each of the links for bending, cracks in weld areas or
shoulders, transverse nicks and gouges, weld splatter, corrosion pits, striation (minute
parallel lines) and chain wear, including bearing surfaces between chain links. Replace a
chain that fails any of the inspections. Check lubrication and lubricate if necessary. See
'Load Chain'under LUBRICATION."
