Hooks are used in lifting systems as a connection between the load to be lifted and the wire rope or chain slings. There are different types of hooks with their specific designs to suit a particular purpose. Eye hooks and swivel hooks are designed for wire rope or chain.

Note: It is required that the products are regularly inspected and that the inspection should take place in the safety standards. This is required because the products in use may be affected by wear, misuse, overloading etc. with a consequence of deformation and alteration of the material structure. Inspection should take place at least every six months and even more frequently when the hooks are used in severe operating conditions.
