摘要： The present invention relates to a lifting hook (1) that can be used to lift loads using lifting gear, comprising a hook-shaped part (3) which hooks onto the load that is to be lifted and a chain length reducer (5) secured to the hook, the said reducer (5) comprising, on the one hand, an orifice (17) the dimensions of which allow the links of the chain (7) to pass through and then allow one (13) of the said links to be locked in position when the said chain (3) is taut and, on the other hand, means (21) for partially closing off the orifice (17) which are hinged so that they can be released manually simply by pressing them so as to allow the length of the chain (7) to be adjusted, notable in that the reducer (5) comprises a closure finger (10) that closes off the hook-shaped part (3) to prevent the load from becoming unhooked, and in that the closing-off means (21) comprise self-locking means (24) which hold the closure finger (10) in the locked position on the part (3) of the hook as long as the closing-off means (21) are disengaged from the orifice (17) and have not yet been returned to a position in which they bear against the external face (23).
