Which component is used to connect the rigging assembly to the hoisting hook?

• A. Shackle
• B. Hook design
• C. Link
• D. Eyebolt

Answer: (B)

Shackle is used to connect the rigging assembly to the hoisting hook. It provides a secure, removable connection that is rated for the load and adaptable to different rigging configurations. You open the shackle pin, place the rigging (slings, chains, or links) through the shackle’s ears, and then close and pin it. This setup keeps the load bearing surfaces aligned, distributes the load through the shackle body, and protects the hook’s latch from wear or accidental release.

The hook’s own design can affect how attachments fit, but the standard, reliable connector for linking rigging to the hook is the shackle because it offers a proven, inspectable, load-rated connection. A link can work in some configurations, but shackles are preferred for their strength and ease of use. Eyebolts are for attaching to fixed points, not for joining rigging to a hoisting hook.
