SHACKLES Avoiding eccentric loading

To avoid eccentric loading of the shackle a loose spacer may be used on either end of the shackle pin.
Do not reduce the width between the shackle jaws by welding washers or spacers to the inside of the shackle
eyes or by narrowing the jaws, as this will affect the WLL of the shackle.
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.

Avoiding pin rotation

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.

Chemicals
Shackles should not be immersed in acidic solutions or exposed to acidic fumes or other chemicals that are
potentially harmful to 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. 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 shall 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.
