The lifting hooks are safety critical components due to the fact that it is the hook that carries all the load when picking up and carrying a container. Hooks are a wearing part and should be inspected for wear and or damage on a regular basis.

1. Check hook for cracks. Replace hook if damaged.

2. Check inside angle of hook. New hooks have 22 mm (0.87 in.) of material between flat portion of hook and top of hook. The hook should be replaced if worn area leaves less than 15 mm (0.59 in.) from start of wear area to flat portion of hook. See Figure 9 and Figure 10.

3. Check wear area of hook where corner casting of container is carried. This area should be inspected and when wear is more than 5% of original thickness, hook should be replaced. See Figure 9 and Figure 10.

4. Check tightness between nuts and threads of hook. Hook should be replaced if threads of hook become worn. See Figure 9.

5. The pin that hook is secured through can wear and should be replaced if excess play is discovered.
