Classification A lifting hook is classified a) according to its method of attachment (e.g. shank hook, Figure 1 to 4, eye hook, Figure 5 to 9, clevis hook, Figure 10 to 15, swivel eye hook, Figures 16 and 17), and b) according to its shape or other defining characteristics, including its intended use (e.g. ramshorn hook, self-locking hook, foundry hook). NOTE For practical reasons some combinations of the method of attachment and the defining characteristics are not used. Figures 1 to 17 give typical examples of the most frequently used types of hook and the nomenclature.
