A mounting system for a vehicle with one or more cross members. The mounting system includes a mounting rail including a mounting platform and at least one mounting slot being formed in the mounting platform. The mounting system includes a panel bracket coupled to the mounting rail that is configured to receive at least one guard panel. The mounting system includes at least one clamping body removably coupled to the mounting platform of the mounting rail. The at least one clamping body is configured to engage a cross member and the mounting platform is configured to engage the cross member so as to clamp the cross member between the at least one clamping body and the mounting platform.

A trailer frame includes a rear bolster, cross-members, and corner gussets extending forwardly from ends of the rear bolster. A rear impact guard includes a bumper positioned at the rear end of the trailer and spaced below the rear bolster, pair of outboard posts, and at least one inboard post. The outboard posts extend between the bumper and the rear bolster adjacent respective opposed distal ends of the bumper, and the inboard post extends between the bumper and the rear bolster between the outboard posts. Each of the pair of outboard posts has a lower end that overlaps with a respective mounting bracket that protrudes upwardly toward the rear bolster from the bumper such that mounting holes of the outboard posts align with mounting holes of the mounting brackets. A laterally-outboard panel of each mounting bracket extends obliquely from the bumper in a direction with a laterally-outward component.

A chassis assembly for a vehicle is provided. The chassis assembly includes: an upper frame structure having at least two longitudinally extending upper side regions arranged on opposite sides of a longitudinal centre line. The upper side regions are connected to each other by upper connection portions. A front crash structure is configured to absorb energy during an impact generated from a vehicle collision, and extends in a transverse direction. The upper frame structure is connected to said front crash structure; wherein said chassis assembly further comprises: a lower frame structure having at least two longitudinally extending lower beams arranged on opposite sides of the longitudinal centre line, said lower beams being connected to each other by lower connection portions, and said lower frame structure is connected to said upper frame structure and to said front crash structure.

A refrigeration trailer condenser protection apparatus having a pair of front rails with connection rods disposed thereon for connecting a street side bracket and a curb side bracket, the street side bracket and curb side bracket having mounting holes for mounting the protection apparatus to a lower side of the condenser unit.

A reinforcement structure (10) comprising an inner member (14) at least partially secured within a shell (12), wherein the inner member is secured within the shell so that one or more abutment portions (18) of the shell are positioned in receiving portions (20) of the inner member, to create at least a partial press-fit condition between the inner member and the shell.

Vertical bars extend downwardly from the structural siderails of a trailer frame to a guard bar extending parallel to the longitudinal axis of the trailer, thus forming a side underride guard. Two side underride guards are fixed to the structural siderails of the trailer. The guard bars are located vertically below the bed of the trailer to have an effective ground clearance of twenty-seven inches. Lateral bracing of each guard bar extends from the guard bar to the structural siderail across the trailer. Bracing at the trailing end of the side underride guards employs a K-brace to provide an air brake hose non-chafing zone. The K-brace is displaced from the trailer bed.

A rear impact guard includes at least one vertical member, and a horizontal member connected to a distal end of the at least one vertical member, the horizontal member having a plurality of through passages allowing for air flow through the horizontal member.
