Abstract: Described herein are illustrative payload carrying machines and dump body linkage. An example vehicle can include a frame and a dump body movable relative to the frame. In the example vehicle, an articulation mechanism can be connected to both the dump body and the frame. The articulation mechanism can be a four-link system including a first pair of links can be coupled to the frame and dump body and a second pair of links can be coupled to the frame and dump body. The second pair of links can be longer than the first pair of links.

Abstract: A dumper body is disclosed. The dumper body may include a pivot assembly. The dumper body may include at least one of: a set of ribs, wherein the set of ribs is connected to the pivot assembly such that the set of ribs is comprised of multiple respective discontinuous structures, and a set of stringers, wherein the set of stringers includes a respective stringer cut-out around an outside surface of a bed plate of the dumper body at a point where a top plate of the dumper body connects to an inside surface of the bed plate.

Abstract: A liner for a machine body includes a first layer including a first polyurethane having first material characteristics, and a second layer coupled to the first layer. The second layer includes a second polyurethane having second material characteristics different than the first material characteristics, and the first layer and the second layer are chemically bonded to one another. A liner system includes a liner and a liner retention system configured to couple the liner to the machine body. The liner retention system includes at least one retention strip configured to be coupled to the machine body. The retention strip has a cross-section forming a lateral profile. At least one edge of the liner has a shape configured to substantially correspond to the lateral profile of the retention strip.
