摘要： A truck body with geometric features that improve material flow while the truck body is being tilted and the payload is being dumped. These geometric features influence the discharge of the material in the truck to better empty the truck body during dumping and lessen the risk or effect of carryback. The truck body geometry results in less dribble, less hang up, and less carryback. The overall discharge time is also often reduced.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Wear members for use in excavating include a socket having a front stabilizing end that includes a top surface, a bottom surface and side surfaces. At least one of these surfaces is formed with a transverse, inward projection and extends axially substantially parallel to the longitudinal axis of the socket. The socket may include surfaces that generally correspond to exterior surfaces of a nose on which it may be mounted and on which it may be connected to excavating equipment.

摘要： A tip for use on an earth working roll for mining, construction and public works machines such as crushers, surface miners, milling machines and the like includes a working end provided with side relief to reduce drag and wearing, require less power to drive the rolls, and lengthen the usable life of the tip. The working end can also have a generally flat front surface to improve the yield in a crushing or other similar operation. The tip includes a base and a wear cap releasably secured together by a retainer.

摘要： A wear assembly includes an adapter (14) with a nose (18), a wear member (12) with a socket (53) to receive the nose (18), and a lock (16) to secure the wear member (12) to the adapter (14). The nose (18) and socket (53) include complementary rails (35) and grooves (65) that vertically diverge as they extend from the front of the nose (18). The lock (16) can have a tapered construction.
