Abstract: A device for protecting an edge of a bucket including a rail having a retaining notch, the device including a protective part which is designed so as to be slipped onto the rail and which includes at least one locking abutment, the device also including a shim which is designed to be mounted on the protective part so as to be inserted into the retaining notch in order to block the sliding of the protective part, the device including a locking key which is movable relative to the shim, between a first angular position, in which it allows installation and removal of the shim in the window, and a second angular position, in which the key abuts against the locking abutment and thus prevents removal of the shim.

Abstract: The present invention relates to a mechanical system (1), comprising a support (10), a wearing part (20) and a connecting device (30) between the wearing part (20) and the support thereof (10). The device (30) comprises an elastic sheath (40) provided with an internal cavity (47) and with an external wall (44) that is adjustable in a housing (14) of the support (10), and a pin (50) having an elongate body along a pin axis (X50).

Abstract: A mechanical system includes a wear part and a support, belonging to the equipment of a construction machine. The support includes a base, a nose which extends from the base along a main axis, and to each side of the base, a housing for receiving a lug of the wear part. The nose includes a first area located near the proximal end of the nose and which includes at least six planar faces arranged in opposite pairs delimiting sections of a first type, and a second area located near the distal end of the nose and which includes at least six planar faces arranged in opposite pairs delimiting sections of a second type, each planar face of the second area being less inclined, relative to the main axis, than the planar face of the first area, which is located in the extension of the planar face in the proximal direction.

Abstract: A mechanical system (1) includes a support (10), a tooth (20) and a device (30) for interconnecting the two components. The device (30) includes a key (50), a nut (60) and an elastic sheath (40) provided with a wall that is adjustable by deformation in a housing (14) of the support, by screwing between the key and the nut, between an insertion configuration and a locking configuration. The device (30) also includes a support ring (70) inserted between the key and an opening (24) made in the tooth (20). In the insertion configuration of the device (30), the support ring (70) is adjusted in the opening (24), while in the locking configuration of the device (30), the support ring (70) exerts retaining forces on the tooth (20). A heavy-construction machine bucket (G) including such a system (1), and a method for implementing such a system are also described.

Abstract: A mechanical system (1) includes a support (10), a tooth (20) and a device (30) for interconnecting the two components. The device includes an elastic sheath (40) having an inner cavity (48) and an outer wall (44) adjustable in a housing (14) of the support, and a key (50) adjustable in the cavity. The sheath and the key can be rotated together in a fixed manner about a pivoting axis in the housing, between an insertion configuration and a locking configuration, thereby forming a coupling connection between the tooth and the support. The inner cavity extends into the sheath along an eccentric axis that is radically staggered in relation to the pivoting axis. The inner cavity is provided with elements for rotatably securing to driving elements (59) arranged on the key. A heavy-construction machine bucket including such a system, and a method for implementing such a system are also described.
