The cranked shape is particu- larly suitable for applications where the shackles are exposed to multiple loads. The rated size and the nominal load (WLL) are drop-forged into the shack- le which makes it easier to select the proper sling gear. In general, the nominal load must not be exceeded. The designs with nut and split pin (Type B) are normally recommended for permanent connections. The bolts are allowed to rotate, and the nuts are secured against inadvertent loosening with a split pin. The operating instruction contains further guidelines and is included with every shackle (see also at www.ganternorm.com/en/service ).
