Abstract:
An assembly for mounting a wear member to excavating equipment comprising:a base adapted to be fixed to a digging portion of an excavator, the base including a first coupling configuration, a convex front bearing surface curved across substantially the entire front bearing surface, and a rear bearing surface; a wear member including a second coupling configuration that fits with the first coupling configuration to prevent release of the wear member except in a release direction, a concave abutting surface curved across substantially the entire abutting surface to abut the front bearing surface, an opening having a bearing wall, and a forwardly projecting working portion, wherein the front bearing surface and the abutting surface are each curved in two perpendicular directions; and a lock received into the opening to oppose the rear bearing surface and the bearing wall of the opening to prevent release of the coupling configurations in the release direction and thereby hold the wear member to the base.
