The invention relates to a hook (10), which may for example be used with a crane to lift heavy loads. In one embodiment, the hook may have a load-bearing portion (12) and an arm portion (14) where the arm portion can pivot relative to the load-bearing portion between open and closed configurations and may have a locking mechanism (20, 21, 29, 30, 32) that can lock the arm portion with respect to the load-bearing portion in the open configuration of the hook, in which configuration the arm portion and the load-bearing portion together define a discontinuous boundary. The hook may also be provided with a suspension portion (74), and the suspension portion, the load-bearing portion and the arm portion may be pivotally coupled with respect to each other.
