What is the purpose of the safety latch on hooks?

• A. To prevent the load from slipping off
• B. To prevent the hook from accidentally detaching or releasing the load
• C. To attach to the rigging
• D. To indicate load weight

Answer: (B)

Safety latch on hooks serves as a positive safeguard to keep the load secured on the hook during lifting and movement. The latch is a spring-loaded catch that closes over the hook opening, so the load can’t unintentionally slip free if the hook tilts, swings, or the rigging shifts even slightly. This keeps the load from being released by accident, which is the central safety concern in crane operations. It isn’t about attaching the hook to the rigging or about indicating weight—those are handled by other parts of the system. For best safety, the latch should be kept closed when a load is on the hook, and both the latch and hook should be inspected regularly for damage or wear.
