2. HOOKS. Check for wear or damage, increased throat
width, bent shank or twisting of hook. Replace hooks
which exceed the throat opening and/or saddle dimension
discard widths specified in Table 2 (refer to Dwg.
MHP0040) or exceed a 10° twist (refer to Dwg.
MHP0111). If the hook latch snaps past the tip of the hook,
the hook is sprung and must be replaced. Replace Bullard
Burnham hooks if the gate no longer contacts the hook tip.
Refer to Dwg. MHP0662. Refer to the latest edition of
ASME B30.10 “HOOKS” for additional information.
Check hook support bearings for lubrication or damage.
Ensure they swivel easily and smoothly.
WARNING
• All new, altered or modified equipment should be inspected
and tested by personnel instructed in safety, operation and
maintenance of this equipment to ensure safe operation at
rated specifications before placing equipment in service.
• Never use a hoist that inspection indicates is damaged.
Frequent and periodic inspections should be performed on
equipment in regular service. Frequent inspections are visual
examinations performed by operators or service personnel and
include observations made during routine equipment operation.
Periodic inspections are thorough inspections conducted by
personnel trained in the safety, operation and maintenance of
this equipment. ASME B30.16 states inspection intervals
depend upon the nature of the critical components of the
equipment and the severity of usage.
The inspection intervals recommended in this manual are based
on intermittent operation of the hoist eight hours each day, five
days per week, in an environment relatively free of dust,
moisture and corrosive fumes. If the hoist is operated almost
continuously or more than eight hours each day, more frequent
inspections will be required.
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 designated personnel trained in
safety, operation and maintenance of this equipment. A
determination as to whether a condition constitutes a safety
hazard must be decided, and the correction of noted safety
hazards accomplished and documented by written report before
placing the equipment in service.
Records and Reports
Inspection records, listing all points requiring periodic
inspection should be maintained for all load bearing equipment.
Written reports, based on severity of service, should be made on
the condition of critical parts as a method of documenting
periodic inspections. These reports should be dated, signed by
the person who performed the inspection, and kept on file where
they are readily available for review.
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 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 (such as abnormal
noises).
1.
OPERATION. Check for visual signs or abnormal noises
(grinding etc.) which could indicate a potential problem.
Make sure controls function properly and return to neutral
when released. Check load 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.
