Anchor Handling Course

Pin Extractor

As torsion tension builds up in wires that have been under heavy load this will result in violent movement of the wires when disconnected.

Removing of pins, in shackles, dismantling of other connecting links e.g. Pear – and Kenter link, from systems that have been under tension and where torsion is likely, should only take place by use of a tugger or capstan wire together with a chain - / wire sling or a Pin Extractor.

Occasionally people have been injured when a crowbar has been used for this action, so that is why a crowbar never should be used to punch pins out of shackles where the wire has been under tension.

When using the tugger or capstan wire together with a sling or Pin Extractor, the safety is considerably improved.

See the Pin Extractor in use on an 85 T shackle on the following page.

The wire from either the tugger or the capstan is fixed on the Extractor, which is hooked on to the shackle pin. The pin is now easily pulled out by use of a tugger or capstan.
