Abstract: A wear member includes a front end and a rearward end, the rearward end having a cavity formed therein. The cavity may include a forward portion, a rear portion, and an intermediate portion. The forward portion may be disposed toward the front end and the rear portion may be disposed toward the rearward end. Each of the rear portion and the forward portion may include at least four surfaces. Each of the four surfaces of the rear portion may converge toward a longitudinal axis of the wear member at a first converging angle, and each of the four surfaces of the forward portion may converge toward the longitudinal axis of the wear member at a second converging angle. The intermediate portion may extend between the forward portion and the rear portion and may include a different number of surfaces in cross-section than the forward portion and the rear portion.

Abstract: Mineral bits (10, 100) and associated mounts (30, 116, 200) for use during excavation and mining operations are disclosed. An exemplary bit (10) has a front region (12) and an opposite rear region (14) and comprises a head portion (16) and a mounting portion (18) secured to the head portion (16). The mounting portion (18) can be configured to be releasably retained by a mount (30). A rounded transition (22) disposed in the front region (12) of the bit between the head portion (16) and the mounting portion (18) provides a clearance (C) between the head portion (16) and the mount (16). Mineral bits (10, 100) disclosed can be inserted into and withdrawn from mounts (30, 1 16, 200) by linear and/or rotational movement.

Abstract: A shroud retention system for a work tool is disclosed. The shroud retention system may have an adapter attached to the work tool. The shroud retention system may also have a shroud that slidably engages with the adapter. The shroud may have a retainer slot. Further, the shroud retention system may have a spring assembly disposed in the shroud. The spring assembly may have a block that slidably moves relative to the adapter. The spring assembly may also have a resilient member disposed between the adapter and the block. In addition, the spring assembly may have a retainer disposed in the retainer slot. The retainer may engage with the block. The retainer may have at least one recess disposed on the retainer front face or on the retainer rear face. The recess may extend partway toward the other of the retainer front face or the retainer rear face.

Abstract: A wear member assembly may include a nose attachable to a bucket lip. The nose may include a rear portion having a first set of substantially planar surfaces including a first, second, and third subset of surfaces. The third subset of surfaces may be angled and positioned between the first subset of surfaces and the second subset of surfaces. The nose may also include a forward portion positioned forwardly adjacent to the rear portion, the forward portion having a second set of substantially planar surfaces including a fourth, fifth, and sixth subset of surfaces. The sixth set of surfaces may be angled and positioned between the first subset of surfaces and the second subset of surfaces. The wear member assembly may also include a wear member having a cavity comprising rear and forward bearing surfaces corresponding to the third and sixth subset of surfaces.

Abstract: A base for forming a tooth for a wheel of a landfill compactor vehicle. The tooth comprises said base and a cap of a cast metal material formed on said base. The base comprises a block, a core and a lip. The block is adapted to be mounted on said landfill compactor vehicle wheel. The core, which is disposed on a cap-facing side of the base, is for receiving molten metal material during a casting operation and remains embedded in the cap. The lip is disposed around a periphery of the base and is also for receiving said molten metal material, in cooperation with the core. The lip at least partially surrounds the cap-facing side and the core.
