A support rocker configured to be pivotally coupled to a rocker attachment interface of a space frame comprises a rocker body having a pivot bore configured to receive therethrough a pivot pin to pivotally couple the rocker body to the rocker attachment interface; and a rocker support insert provided on a top portion of the rocker body. The rocker support insert can be removably coupled to the top portion of the rocker body, and the rocker support insert can define an upward-facing contact surface.

A rocker support insert for a support rocker comprises a support plate configured to be removably coupled to a top portion of a rocker body; and a support padding fixedly coupled to a top surface of the support plate such that a portion of the top surface of the support plate remains exposed. A top surface of the support padding can define a concave upward-facing contact surface, and the support padding can be thicker than the support plate.

A dump trailer and system for a semi-trailer truck are disclosed. The dump trailer and system includes a tub, a coupling plate configured to engage the dump trailer to the tractor, a first hydraulic cylinder hinge, a second hydraulic cylinder, and a draft arm attached to the coupling plate and the tub that cooperate to improve manufacturing economics and/or dumping of a load carried by the dump trailer.

A hydraulic tank for a machine is disclosed herein. The hydraulic tank includes a casing defining an interior space and having an outer surface, an inner surface opposite the inner surface, and a return hydraulic fluid inlet extending through the casing. A first concave member is connected to the inner surface of the casing to form a passage. The passage is positioned and shaped to transport hydraulic fluid from the return hydraulic fluid inlet to another location within the hydraulic tank.

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 safety assembly for off-highway trucks. The safety assembly can include a bracket and an arm. The arm can be coupled to the bracket via a pivot pin. The arm can rotate about the pivot pin. In preparation for operation of the off-highway truck the arm can be rotated around the pivot pin and held in a first position by a positioning pin that is placed at a first position between a left plate and a right plate of the bracket. In preparation for service of the off-highway truck the arm can be rotated around the pivot pin and held in a second position by the positioning pin placed at a second position between the left plate and right of the bracket.

An assembly (100) to be mounted on a vehicle to support a load receiving body on the vehicle. The vehicle having a forward direction of travel with the load receiving body being tillable. The assembly including a primary frame (110), having a longitudinal axis X, that is to be attached to the vehicle. A secondary frame (120) extending between the primary frame and to be attached to the load receiving body. A hinge (170a,b) pivotally attaches the primary frame to the secondary frame for angular movement about a pivot axis that is transverse to the longitudinal axis so that the secondary frame is movable between a lowered position and a raised position. The lowered position has the secondary frame adjacent to the primary frame and the raised position having the secondary frame raised at an acute angle at the hinge. A first actuator (161) is pivotally attached to a portion on the primary frame and is pivotally attached to the secondary frame and operable to cause angular movement of the secondary frame about the pivot axis. A second actuator (162) is attached to the portion and mounted to primary frame and operable to cause movement of the hinge portion in a direction generally parallel to the longitudinal axis X.

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.

Embodiments of the present invention provide a safety support apparatus for truck beds elevated in a raised position. The bottom of the safety support apparatus provides a support platform a clamping mechanism which adjusts to truck chassis designs providing rails of varying thicknesses. The top of the safety support apparatus provides a receiver which may be configured with several modular components to engage the bottom of an elevated truck bed.

A lift system for supporting cargo on a vehicle comprising a vehicle frame, the lift system comprises a cargo platform assembly and a displacement system. Operation of a drive system causes axial rotation of at least one drive axle. Axial rotation of at least one drive axle causes at least one drive link assembly to pivot about a drive axle axis. Pivoting of the at least one drive link assembly about the drive axle axis displaces the cargo platform between a stowed configuration and a lowered configuration. First and second distal axes are forward of the drive axle axis when the lift system is in the stowed configuration and rearward of the drive axle axis when the lift system is in the lowered configuration.
