摘要

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.
