Abstract

An earthworking loader bucket has a specially designed bottom side reinforcement structure which includes a unitary base plate member extending rearwardly from the bottom side front bucket lip and having a front side edge welded to the rear side edge of the lip. Slots are formed in the rear side edge of the base plate and receive bottom end portions of plate-shaped lifting and tilt ears transversely welded to the curved rear side wall of the bucket. Closeout plates are interposed between the bucket rear side wall and rear side portions of the base plate, and the bottom end portions of the ears are welded to the base plate. A spaced plurality of elongated ear extension members longitudinally extend forwardly from the ear member bottom end portions and along adjacent bottom side portions of the base plate and lip, with the extension members being welded to the ear member bottom end portions, the base plate and the lip. The ear extension members function to transfer ear operating loads to bottom side portions of the base plate and the lip, to substantially reinforce the bottom side of the bucket, and also serve as downwardly projecting wear runners to shield bottom side portions of the base plate and lip against abrasion wear.
