What should be done about a damaged crane hook?

• A. Continue with reduced speed.
• B. Tape the hook and continue.
• C. Tighten the hook bolts.
• D. Remove from service immediately and replace.

Answer: (D)

A crane hook is a critical link in the lifting system, and any damage can compromise its ability to hold and release loads safely. If a hook is damaged, it can fail suddenly under load, causing the load to slip or drop and potentially injure people or damage property. Because of that risk, the only safe action is to take the crane out of service immediately and replace the damaged hook with a certified, serviceable one.

Trying to continue operation with a damaged hook—even at reduced speed—is not acceptable, since the defect can worsen under load. Temporary fixes like taping the hook or tightening bolts do not restore the hook’s strength or integrity and can conceal the defect. The appropriate response is to tag the crane as out of service, remove the hook from duty, and arrange replacement through qualified personnel, then document the incident and inspection results.
