3. Chain: Examine each link for bending, cracks in weld areas or shoulders, traverse nicks and
gouges, weld splatter, corrosion pits, striation (minute parallel lines) and chain wear, including
bearing surfaces between chain links (refer to Fig 10. MHP0102). Replace a chain that fails any
of the inspections. Check chain lubrication and lubricate if necessary.
(Fig 10. MHP0102)
Excessive wear or stretching may not be apparent from visual observation. At any indication
of wear or stretching inspect the chain in accordance with instructions in "Periodic Inspection".
A worn load chain may cause the load sheave to wear rapidly. Inspect the load sheave and
replace if damaged or worn.
4. Controls: During operation of hoist, verify response to pendant is quick and smooth. Make
sure that the controls return to neutral when released. If hoist responds slowly or movement
is unsatisfactory, do not operate hoist until all problems have been corrected.
5. Electrical System: Visually inspect all connections and components for indication of damage
or loose connections. Shut off and disconnect power prior to removing inspection covers,
repairing any damage or tightening connections.
6. Hook Latch: Make sure the hook latch is present and operating. Replace if necessary.
Do not use hoist if hook latch is missing or damaged.
7. Chain Reeving: Make sure welds on standing links face in toward load sheave. Reinstall
chain if necessary. On double fall hoists, make sure chain is not capsized, twisted or kinked.
Adjust as required. Refer to Fig 11. MHP0043.
(Fig 11. MHP0043)
8. Brake System: Check to make sure the brake is able to hold the rated load without slippage.
Check air gap.
