A dumper vehicle includes: a frame comprising a front end and a rear end; front and rear wheels mounted to the frame; an operator seat mounted to the frame; and an open topped container for carrying a load therein mounted to the frame between the front and rear wheels, wherein the container is moveable between a transport position for transporting a load and a discharge position for discharging of a load; wherein the container defines an upper extent thereof, and wherein said upper extent of the container decreases in height with respect to a lower extent of the wheels towards the front end of the frame, when the container is in the transport position.

A frameless dump trailer is provided. The frameless dump trailer includes a forward body portion and a rear body portion. Each body portion is formed from two or more panels joined together with butt-joint welds. The forward portion is first formed by welding planar sections together. After the body portion is formed from the plurality of planar panels, the larger planar portion is rolled in a rolling system to define the arcuate shape of trailer body. Then, the forward and rear body portions are welding together with a transversely extending butt-weld.

A front tower for a truck body of a machine includes a beam member. The front tower includes a landing plate. The front tower also includes a first plate member connected between the beam member and the landing plate, and a second plate member disposed adjacent to the first plate member. The second plate member is connected between the beam member and the landing plate. The front tower includes a first side plate and a second side plate spaced apart from the first side plate. The front tower further includes a cover plate assembly extending between the first side plate and the second side plate. The cover plate assembly, the first side plate, and the second side plate enclose the first plate member and the second plate member.

The disclosure relates to a lining for a haul truck body, said lining comprising a plurality of main lining elements arranged to extend over main surfaces of said haul truck body, and a plurality of transition lining elements arranged to extend over edge and/or corner portions of the haul truck body, wherein each transition lining element forms a lining transition between at least two non-parallel main lining elements of said plurality of main lining elements, and wherein said plurality of transition lining elements comprises at least one non-linear transition lining element which has a first and a second leg portion extending in non-parallel first and second leg directions, respectively. The disclosure further relates to a transition lining element for a haul truck body and a method for assembling a lining.

The disclosure relates to a lining for a haul truck body, said lining being arranged to extend over a haul truck body for carrying a load, wherein the lining is formed by a plurality of lining elements comprising at least a first type of lining elements, termed load-breaking lining elements, and a second type of lining elements, different from the load-breaking lining elements, said load-breaking lining elements being structured and arranged to restrict, to a higher degree than the second type of lining elements, movement of said load in relation to the lining. The disclosure further relates to a haul truck body comprising the lining and a haul truck comprising the haul truck body.

The disclosure relates to a lining for a haul truck body, said lining being arranged to extend over surfaces of said haul truck body, wherein said surfaces define at least one impact region and at least one wear region; wherein said lining within said at least one impact region presents one or more impact lining elements; wherein said lining within said at least one wear region presents one or more wear lining elements; and wherein said impact lining elements have a higher impact resistance than said wear lining elements and said wear lining elements have a higher wear resistance than the impact lining elements. The disclosure further relates to a haul truck body comprising the lining and a haul truck comprising the haul truck body.

A pivot assembly is disclosed. The pivot assembly may include plates. The plates may be connected to cover plates associated with respective portions of a stringer that intersect the pivot assembly. The plates may be connected to a rib that interests the pivot assembly perpendicular to the respective portions of the stringer. The cover plates may be connected to the rib at a respective end of the cover plates. The pivot assembly may comprise a respective pivot bore in the plates. The pivot assembly may comprise respective doublers around the respective pivot bore. The respective doublers may include a first doubler located on an outside surface of a plate, of the plates, and a second doubler located on an inside surface of the plate. The pivot assembly may comprise gussets. The gussets may be connected to the second doubler, the plates, and a respective cover plate of the cover plates.

A truck body includes a front wall, side walls, and a floor. The floor has panels disposed at predetermined angles from the horizontal that, with the other parts of the body, form a payload volume within the body. The floor also includes a tail panel disposed at a lesser angle from the horizontal to facilitate the shedding of the payload when dumping, and further to maintain the center of mass of the payload in a generally forward position during dumping.

A dump truck configured to move in both front and back directions and dump loads in a first one of the directions includes: a chassis including an engine within a wheelbase; and a dump body covering an upper portion of the chassis across an entire length in travel direction and an entire width in vehicle width direction, the dump body supported so as to be able to be raised and lowered via a hinge by a side of the chassis near which loads are dumped. The dump body includes: a first inclined a side of the dump body from portion rising upward from a bottom portion of the dump body toward the side thereof from which loads are dumped; and a second, inclined portion inclined downward from an upper end of the first inclined portion to an end of the side of the dump body from which loads are dumped.

A dump body for a dump trailer or a dump truck comprises modular components of tempered aluminum alloy joined together with mechanical fasteners to form modular subassemblies. Welding or other high-temperature joining processes are not required for fabrication of the dump body, and thus the full strength of the tempered aluminum alloy is retained. Methods for assembly of the modular components to form the modular subassemblies and for assembly of the modular subassemblies to form the dump body using mechanical fasteners are provided in addition to designs for modular components and modular subassemblies.
