Which part of the shackle is always placed on the hook of a crane?

In a shackle, the correct part that is always placed on the hook of a crane is the pin. The pin serves as the attachment point for the shackle to the hook. When the shackle is connected to the crane’s hook, the pin effectively secures the load by allowing the body of the shackle to hold the item being lifted, while the pin prevents the body from disconnecting from the hook.

The body of the shackle, although integral to its function, is not directly placed on the hook; it acts as the loop or frame that supports the load. The latch and screw may serve specific purposes in certain shackle designs, such as providing additional security by preventing accidental disconnection, but they do not provide the primary connection to the hook itself. Understanding the function of these components is essential for safe rigging practices in lifting operations.
