Before operating the hoist, it is important to inspect the hook to ensure it is safe and has no defects before lifting a load. There are some key things to look for when inspecting an FDA conveyor hook: Deformation Deformation can be a sign of overloading, side pulling, or utilizing improper rigging techniques. In some cases, deformation of the hook may be noticeable. Look for any bends, twists, cracks, or sharp edges that could damage your sling. Measuring the width of the hook mouth can detect subtle deformation of the hook. Compare the measured hook size with the parameters in the product's instructions. If it exceeds the original size by 5%, the hook should be stopped from use.

In addition, some hooks have pre-made marks or protrusions between the hook mouth and the hook seat, which are reference points for measurement. Regular lifting equipment manufacturers will provide hook measurement methods and corresponding sizes in their product manuals.

2 Wear and corrosion

Check for excessive wear or rust on the hook. If this wear or rust exceeds 10% of the original cross-sectional size of the hook, the hook should be stopped from use.

When you can put your fingernail into a crack or gouge on the hook, it means the hook can no longer be used.

4 Safety buckle

Lifting regulations stipulate that the hook should be equipped with a safety buckle and must be operable. The safety piece fixes the sling in the hook when the hook is not under force. The safety buckle is not a load-bearing part and can be easily damaged when the sling is not used correctly.

Check the safety buckle and make sure that the safety buckle overlaps the hook tip when in the closed position and opens and closes normally.

With safety buckle:

If you see any abnormality on the hook, please stop using the hook/hoist immediately. Do not use it again before replacing or repairing.
