All hooks must be equipped with an effective positive _____________?

• A. Safety Pin
• B. Locking Ring
• C. Cap
• D. Safety Latch

Answer: (D)

Hooks are designed to keep the load secured during lifting, and a positive safety latch provides that reliable retention. The latch physically blocks the hook gate from opening as the hook moves, tilts, or the load shifts under dynamic crane loads. This prevents the load from slipping off the hook even when angles change or the equipment vibrates. A safety latch is built to stay closed under load and is designed to function in dirty, windy, or rugged environments, which is essential in crane operations. The other options don’t offer the same guaranteed positive retention: a safety pin isn’t a universal mechanism for keeping the hook gate closed, a cap doesn’t lock the gate, and a locking ring doesn’t provide the necessary positive closure under all lifting conditions.
