A finish machined rear pivot support a dump body of a haul truck can comprise a pair of rear pivots spaced apart from each other in a first direction, and a cross-member extending in the first direction between the rear pivots. The rear pivots can be respectively welded in-line with longitudinal support body members on a bottom of the dump body. The cross-member can extend from inward-facing sides of the rear pivots. Each of the rear pivots can include two cut-outs spaced apart from each other in a second direction perpendicular to the first direction. The cut-outs can be provided over corresponding one of transverse support body members on the bottom of the dump body.

A system for detecting distribution of a weight of a payload in a dump body of a vehicle includes first sensors, second sensors, and a controller. The dump body is pivotable about pins to be selectively seated and titled to a frame of the vehicle. The first sensors are arranged between the dump body and the frame, and detect components of the weight of the payload exerted through the dump body when the dump body is seated relative to the frame. The second sensors are arranged correspondingly within the pins, and detect components of the weight of the payload exerted through the dump body. The controller determines a status of payload distribution in the dump body based on the component of the weight of the payload detected by the first sensors and second sensors, and generate a notification to indicate the status of payload distribution.

A tilt bed for a multi-utility vehicle that is movable from a flat conveying positon to a tilted dump position. The tilt bed has a lift handle construction that combines a molded thermoplastic portion integral with the tilt bed body and a handle bracket that provides reinforcement in the appropriate location to provide a sturdy handle for ease of lifting. The bracket has at least a yoke shape underlying the bed body and is co-extensive with a neighboring edge of the bed body to provide a comfortable lift area. The bracket is rigidly attached to the bed body, and may also have a more robust shape such as a closed loop. For added stiffness and strength, the bracket may also be rigidly connected to the bed frame.

A tilting truck bed includes a bed body configured to load materials, lifting supports, shock absorber supports and a shock-absorbing pad assembly. The bed body includes a first bottom plate, a front plate, a tail plate, a left side plate, and a right side plate that are welded to upper edges of the first bottom plate. The lifting supports are symmetrically mounted on the tail plate and hinged to the frame to realize the tipping of the bed body. The shock absorber supports are symmetrically mounted on both sides of the front part of the first bottom plate, wherein the shock absorber support includes a shock absorber support main body and a gap adjusting device.

A vehicle that includes a frame and a truck body coupled to the chassis. The truck body includes a body floor, first sidewall, second sidewall, front wall, and body rear, or tail surrounding an interior. A heat transfer system is removably coupled to the truck body and includes a component extending along and secured to one of the body floor, first sidewall, second sidewall, front wall, or body rear, or tail to transfer heat to an interior surface of the truck body.

A dump truck (10) has a tipping body (30) in the form of a shell structure for holding material, which is pivotally mounted to the chassis (19) of the dump truck (10) for tilting about a transverse tipping axis. The truck (10) has at least one hoist pivot (33) configured for connection to a respective tipping ram (18) mounted to the chassis (19). The hoist pivot (33) is positioned to abut against the underside of the shell structure (36) when acted upon by the tipping ram (18) and tilt the tipping body (30) about the tipping axis. However, the hoist pivot (33) is not integral or welded to the shell structure (36). High stress concentrations are thereby avoided or significantly lessened in the tipping body shell in the vicinity of the hoist pivot, and there are no welds between the hoist pivot and the shell structure to become fatigued or crack. This enables a simplified and lighter single skin shell structure to be used for the tipping body.

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.

A vehicle trailer with a pair of engagement arm assemblies, one engagement arm assembly on either lateral side of the vehicle trailer, the vehicle trailer having a draw assembly for engagement with a vehicle, a chassis associated with the draw assembly and mounted on at least a pair of wheels and having at least a pair of spaced apart side rails, each side rail mounting an engagement arm assembly, each engagement arm assembly including an elongate rigid arm mounting an elongate engagement key, a first length adjustable arm associated with the elongate engagement key and a second length adjustable arm associated with the elongate rigid arm such that the elongate rigid arm can be raised and lowered to load and unload an object relative to the trailer and the elongate engagement key can be pivoted to tip an object mounted relative to the trailer.

Retention system for a load carrying container, comprising a retention portion arrangeable at or near a rear end of a load carrying container. The retention portion is pivotable between a first, raised position and a second, lowered position; and a drive element is used for moving the pivotable retention portion between the first and second positions.

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.
