Frequent Inspection
For hoists in continuous service, frequent inspection should be made by operators at the
beginning of each shift. In addition, visual inspections should be conducted during regular
operation for any damage or evidence of malfunction.
1. Operation: Check for visual signs or abnormal noises (grinding etc.) which could indicate a potential
problem. Check load chain feed through the hoist. If chain binds or jumps, clean and lubricate. If
problem persists, replace the chain. Do not operate the hoist until all problems have been corrected.
2. Hooks: Check for wear or damage, increased throat width (refer to Fig 8. MHP4161 and
refer to Table 2), bent shank or twisting of hook (refer to Fig 9. MHP0111). Refer to the latest
edition of ASME B30.10 "HOOKS" for additional information. Check hook support bearings for
lubrication or damage. Check hooks swivel easily and smoothly.
