Abstract: A wear member for attaching to a digging edge of a bucket includes a front end and bifurcated legs extending rearwardly from the front end. Each leg includes an inner surface to face the digging edge, a rear wall, and a lock opening to receive a lock therethrough. At least one of the bifurcated legs includes a front portion, a rear portion, and a coupling feature. The rear portion defines a stabilizing region comprising a front facing lateral wall forward of the rear wall.

Abstract: A lip for an excavating bucket with a front beam and a rear beam extending along the length of the lip and defining at least one recess between them. The front beam includes noses extending forward of the beam for mounting ground engaging tools. Ribs extend between the front beam and the rear beam. The ribs separate recesses extending between the beams.

Abstract: A bucket for use with a cable shovel includes a shell and a door collectively defining a cavity for gathering material to be excavated. The door is pivotally secured about a pivot axis on the shell so that the door can pivot between a closed position for gathering the material and an open position for dumping the material. The pivot axis is positioned forward of an exterior surface of a back wall of the shell to create a shallower and less forceful door swing during dumping. The door has a front portion that is bent towards a digging edge on the shell so that the door has greater strength, improves bucket loading, and moves a portion of the shell away from the highest wear area.

Abstract: A wear assembly with strain relief protects exposed surfaces of excavating equipment such as a bucket lip. Wear components may include a seat where loads are applied, welding flanges flanking the seat on opposite ends of the component welded to the equipment, and strain relief areas between each welding flange and the seat. The strain relief balances stresses from loading in the wear assembly across the weld flange to limit cracking from stress concentrations. Strain relief may include modification of material properties or modification of component configuration to reduce stiffness of the component between the weld flanges and the seat.

Abstract: A coupling link for connecting two parts together includes link components (which each form a partial link) that are joined together with a removable support. The support and link components are coupled together to withstand high loads and/or adverse wear conditions. The inventive construction is strong, durable, efficient, cost effective and easy to use. Wear caps are provided to facilitate extended usable chain life.

Abstract: A wear assembly for excavating equipment includes a base fixed to the excavating equipment, a wear member fit over the base, and a lock to releasably hold the wear member to the base. The wear member includes side relief to reduce drag on the system. The wear member and the base each includes a hemispherical front end and a generally trapezoidal rear portion. The base includes a nose and a stop projecting from the nose to cooperate with the lock without an opening being needed to receive the lock into the nose. The lock is an elongate lock positioned generally in an axial direction and which holds the wear member to the base under compressive loads.

Abstract: An assembly for mounting an excavating tooth particularly suited for a dredge cutterhead includes a base, an adapter, and a lock. The base includes a convex, curved bearing surface that abuts a concave, curved bearing surface on the adapter. The curved bearing surfaces are able to maintain substantially full contact with each other under transverse loading. The undersurface of the base is formed with a groove to improve the strength and durability of the weld.
