Shackles are U-shaped pieces of metal with a pin along the non-curved side. Shackles are used to lift, secure and rig heavy loads, where they act as the final link in a connection chain or sling setup.
Shackles are advantageous if wanting to make a robust physical connection between the load-lifting device (typically a hoist hook or sling) and the payload that needs to be moved or supported.
Regardless of the type of Shackle you’re using, they will always consist of two main components: the body and the pin. The body can have the anchor shape (Bow type) or a chain shape (Dee type). Each body shape can be used with a screw pin or a bolt-type pin. The bolt-type pin in particular is used to ensure safety and that the shackle pin won’t become loose under load or in applications involving vibration or movement.
