Abstract

Device comprising an attachment member (5) and locking cams (9). The attachment member (5) is connected to the boom (1) by the usual rods, is articulated directly on the end of the said boom, forms an L- shape and comprises, at the end of its lower branch (5a), a hook (8) capable of engaging under a beam (16) joining the upper part of the sides of the bucket. The branch (5b) of the attachment member comprises at its upper part a shaft (10) on which is mounted at least one pivoting cam (9) subjected to the action of a spring (12) which tends to cause the said cam to pivot towards the hook (8). The rear part (15c) of the bucket has two flanges (17) connected by a shaft (18), the said flanges forming, below the shaft (18), a cradle (19) in which shaft (10) of the attachment member (5) rests when the hook (8) is engaged with the beam (16), in this position the cam (9) being supported under the said shaft (17). <IMAGE>
