Abstract

The invention relates to a lip for an excavation bucket. The lip includes a lower plate defining a plurality of integral projections along a front edge thereof, an upper plate and a central plate sandwiched between the lower plate and the upper plate so as to form a laminated structure. The upper plate also defines a plurality of integral projections which together with the projections on the lower plate form tool attachment formations in a serrated front edge of the laminated structure for supporting ground-engaging tools on the lip.
