Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly. A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks.
Shackles and hooks are components of rigging used to attach loads and slings to lifting devices. These items along with ropes, chains, and slings make up the “rigging gear.”
Failure of shackles or hooks while loads are being lifted or moved, may cause serious injuries.
