IMPORTANT
Any deciency found on this inspection chart should be corrected before the hoist is put back into service.
Note: Following disassembly of the hoist during inspection, a load test is required by ANSI/
ASME B30.21 and should be done before the product is put back into operation.
Hook Inspection
Warnings:
1. Any OZ hook that requires replacement because of excessive bends, twists, or throat opening
indicates abuse or overloading of the product. Therefore, other load-supporting components of
the product should be inspected for possible damage when such conditions are found.
2. Never repair hooks by welding or reshaping. Heat applied to the hook will alter the original heat
treatment of the hook material and reduce the strength of the hook.
3. Never weld handles or other attachments to the hook.
Hook Inspection Procedure
Where applicable, inspect hooks and measure throat opening at least once a month. Between regular
inspections daily inspections of the hooks should be done. Check for the following:
• Deformation, distortion, twisting, damage
• Missing, bent, or damaged hook latches
• Chemical damage, deformation, or cracks
• Greater than a 10-degree twist from the plane of unbent hook
• Excessive opening or seat wear
Hook Latch
Hook latch inspection should include the following:
Replace hooks that are opened to an extent that the latch does not engage the tip.
Latch should have enough spring pressure to keep it tight against the tip of the hook and
allow it to spring back to the tip when released
