HOOK INSPECTION:
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.
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.
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:
1. Replace hooks that are opened to an extent that the latch does not engage the tip.
2. 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
