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 a designated person. A determination must be made as
to whether a deficiency constitutes a safety hazard before resuming operation.
5.1: Daily Inspection
Before the start of the shift check the following points
Nameplate label, working load limit, Warnings and Instructional information is
clear and present
Hooks-ensure hook latch is working properly, check for wear, corrosion
distortion, nicks, make sure hook rotates freely, all pins, nuts and bolts for
wear and distortion and are assembled properly.
Chain-proper lubrication, and damage such as, nick, gouges, twists, proper
reeving, heat damage, distortion, stretch, excessive corrosion, pitting.
Handle- no distortion, secured properly
Hoist body- any damage, loose or missing parts, heat damage, cracks
It is recommended that you operate unit with a light load to check proper
function. Min of 50lbs times load supporting parts of chain for chain fall and
100 lbs. min per load supporting parts of chain for lever hoist.
5.2: Records and Reports
A written report of periodic inspections must be maintained listing all points inspected
and kept on file where they are readily available for review. Monthly reports should be
made on the condition found in frequent inspections. Reports should be dated and
signed by the person who performed the inspection.
5.3 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.
2. HOOK LATCH. Check operation of the hook latch. Replace if broken or missing.
3. HOOKS. Check for wear - any wear exceeding 10% of the original section
dimension of the hook or its load pin or damage, increased throat width, bent shank
or twisting of hook. Replace hooks which exceed the throat opening discard width
shown in Table 1 (ref. Dwg. H-01) or any twist or deformation. 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. Exam top and
bottom pin engagement holes on hook. Replace if hole has 10% wear or pin
appear loose in any way.
