SHACKLES When a shackle is attached to the top block of a set of wire rope blocks the load on this shackle is increased
by the value of the hoisting effect.

Avoid applications where the load moves over the shackle pin; the pin may rotate and possibly be unscrewed.
If moving of the load cannot be avoided, or when the shackle is to be left in place for a prolonged period or
where maximum pin security is required, use a shackle with a safety bolt, nut and cotter pin or a shackle with
a fixed nut.

Shackles should not be immersed in acidic solutions or exposed to acidic fumes or other chemicals that are
potentially harmful for the shackle.

Point loading

Shackles are used in lifting- and static systems as removable links to connect (steel) wire rope, chain and
other fittings. Most of the times the load bearing component that connects to a shackle is of a rounded
shape. Point loading of shackles during lifting operations is allowed but the minimum dimension of the
rounded component to be lifted should be equal to or bigger than the bow size of the shackle being used.
The maximum load of the configuration is limited by the component with the lowest WLL. Increasing
the contact area by using bigger diameters and/or pad eyes can be an advantage. Sharp edges should
®
be avoided. Green Pin shackles can also be used in below configurations. The maximum load of the
configuration is limited by the component with the lowest WLL.
