Shackles are used in lifting operations and static systems as removable links to connect (steel) wire rope, chain and other fittings. Screw pin shackles are used mainly for non-permanent applications. Safety bolt shackles are used for long-term or permanent applications or where the load may slide on the pin causing rotation of the pin.

All Van Beest shackles have a specific design for a specific application.
Some examples are:
-Green Pin Super shackles which are made out of grade 8 steel. They are designed to be used in confined spaces. The higher material strength is used to reduce the physical dimensions of the product whilst maintaining its WLL and functionality of the product;
- Green Pin Polar shackles are for use in extreme climatic conditions with material properties guaranteed up to temperatures of -40C;
- Green Pin Sling shackles are designed to provide a better radius to the sling it lifts. A bigger radius increases the life span of the sling significantly;
- Another example of functional design is a shackle pin with a square sunken hole. Because of the flat head there is less risk of the shackle getting caught in a net or a line.
These are all examples of highly functional designs, to optimize the use of the Van Beest shackles in daily use.
Shackles used for lifting applications are generally marked with:
- Working Load Limit n e.g. WLL 25 T
- manufacturers symbol n e.g. GP
- traceability code n e.g. HA indicating a particular batch
- steel grade n e.g. 4, 6, 8
- CE conformity code (ConformitEuropnne) n CE
Van Beest Green Pin shackles meet all relevant requirements of the Machinery Directive 2006/42/EC and its latest amendments.
