•
All new, altered or modified equipment should be inspected and tested by personnel trained
in safety, operation and maintenance of this equipment to ensure safe operation at rated
specifications before placing equipment in service.
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.
•
The external placement of coded marks on equipment identifying completed inspections and
operationally certified equipment is an acceptable method of documenting periodic inspec-
tions in place of written records.
Load Chain Reports
Records should be maintained documenting the condition of load chain removed from service as part
of a long-range load chain inspection program. Accurate records will establish a relationship
between visual observations noted during frequent inspections and the actual condition of the load
chain as determined by periodic inspection methods.
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 signs or abnormal noises (grinding etc.) which could indicate
a potential problem. Make sure all controls function properly and return to neutral when
released. Check chain feed through the hoist and bottom block. If chain binds, jumps, is
excessively noisy or "clicks", clean and lubricate the chain. If problem persists, replace the
chain. Do not operate the hoist until all problems have been corrected.
