FIELD: machine building.
SUBSTANCE: group of inventions relates to excavation devices, in particular, an excavator wear assembly on mounting nose of an excavation device. Excavator wear assembly comprises a mounting nose and a wear member. Mounting nose has a rear bearing face, a forward bearing face, an upper bearing face disposed at an angle between the rear bearing face and the forward bearing face, front face, substantially perpendicular to the forward bearing face, and a rib extending over at least part of the upper bearing face, forward bearing face and front face. Wear member has a rearwardly opening socket adapted to receive the mounting nose, the socket being at least partially defined by a top wall, front wall and side walls, the wear member having a recess formed in the top wall and front wall adapted to receive at least part of the rib. Front face of the mounting nose is configured to be supported on the front wall of the wear member, when the wear member is first mounted on the mounting nose.
EFFECT: technical result is the stability of the wear member and the mounting nose.
