The lifting hook is characterised in that it comprises a bushing (2) adapted to be inserted in the eyebolt so as to make the hook modular, meaning that the same eyebolt (1a) and the same bushing (2) can be indifferently used to make a male hook or a female hook, and is further characterised in that it allows the use of an anti-loosening device (3) which improves the reliability of the hook itself.</p> |
