<p>A bucket lip comprises an inner face positioned within an earth-gathering cavity of an excavating bucket and an outer face positioned opposite the inner face and positioned outside of the earth- gathering cavity of the bucket. A front digging edge interconnects the inner and outer faces. A series of spaced apart through-holes are provided to receive locks for securing wear members to the lip, each of the through-holes being open in the inner and outer faces and spaced rearward of the front digging edge. A plurality of bosses, each to be received into a slot in each of the wear members provide support therefor, one said boss being fixed to at least one of the faces of the lip adjacent each said through-hole.</p> |
