A platform trailer neck reinforcement structure includes a first beam reinforcement structure that includes: (i) a first beam inner insert connected to an inner side of the first beam; and, (ii) and a first beam outer insert connected to an outer side of the first beam. The neck reinforcement structure also includes a second beam reinforcement structure that includes: (i) a second beam inner insert connected to an inner side of the second beam; and, (ii) and a second beam outer insert connected to an outer side of the second beam. Internal cross members extend between and interconnect the first beam inner insert and the second beam inner insert. A first group of external cross members are located between the first beam outer insert and the left side rail, and a second group of external cross members are located between the second beam outer insert and the right side rail. Each external cross member comprises an inner segment connected to an outer segment, said inner and outer segments of each external cross member of the first group connected respectively to the first beam outer insert and the left side rail, and the inner and outer segments of each external cross member of the second group connected respectively to the second beam outer insert and the right side rail.

A platform trailer includes a neck reinforcement structure located in the neck region to provide for a reduced height in the neck region of the trailer to increase the cargo-carrying capacity of the trailer. The height in the neck region of the trailer is less than 30% of the height in the rest of the trailer. A fifth wheel plate includes a main portion secured to both the first and second beams of the trailer. The fifth wheel plate includes a bifurcated tail portion including a first tail portion connected to the first beam and a second tail portion connected to the second beam. A kingpin is connected to the fifth wheel plate and is adapted to be engaged by an associated tractor fifth wheel.

A heavy duty mobile metal scrap compactor, shear and baler machine includes a frame having a front end, an intermediate section and a rear end. A power, hydraulic and control station is mounted on the rear end of the frame. A compactor/baler station is mounted on the intermediate section of the frame. A guillotine shear station is mounted on the front end of the frame. At least three axels with twelve wheels are mounted under the frame at the rear end. Vertically adjustable feet are mounted under the frame at the intermediate section and front end. A booster trailer is removably mountable to the rear end of the frame to spread some of the machine's weight onto the booster when moving the machine down a highway. A gooseneck hitch is removably mountable to the front end of the frame adapted to be hooked up to a fifth wheel of a tractor vehicle to move the machine around to a desired parking position.

A spread axle assembly for a trailer has the ability to pivot about itself to achieve a storage configuration that advantageously shortens the overall length of the trailer and reduces tire wear. It also has the ability to extend between a close position in which the rear axle of the trail is proximate to its axle and one or more spread or extended positions for better distribution of a load carried by the trailer.

A platform trailer includes a neck reinforcement structure located in the neck region. The neck reinforcement structure includes a first beam reinforcement structure located adjacent an inner side of the first beam that is oriented toward the second beam, and a second beam reinforcement structure located adjacent an inner side of the second beam that is oriented toward the first beam. A plurality of internal cross members extend between and interconnect the first and second beam reinforcement structures. A fifth wheel plate is fixedly secured to and that extends between both the first and second beams. A kingpin is connected to the fifth wheel plate and is adapted to be engaged by an associated tractor fifth wheel. The neck reinforcement structure allows for use of aluminum alloy beams with a reduced height in the neck region of the trailer.

The shipping container hitch and wheel attachment comprises a hitch structure, a plurality of wheel structures, and an intermodal freight container. The hitch structure removably attaches to the intermodal freight container. Each wheel structure selected from the plurality of wheel structures removably attaches to the intermodal freight container. The hitch structure and the plurality of wheel structures temporarily modify the intermodal freight container such that intermodal freight container can be directly towed by a tractor. By directly towed is meant that the intermodal freight container forms its own trailer structure and does not require the service of a separate trailer such as a flatbed trailer. The hitch structure attaches the intermodal freight container to a tractor. The plurality of wheel structures form a chassis that allows the intermodal freight container to be towed.

A trailer system with a trailer and a booster is provided. The trailer can have a hitch assembly provided at a front end of the trailer, a load bed provided behind the hitch assembly, and an axle assembly. The booster can have a connection assembly pivotally connecting the booster to a rear end of the trailer and an axle assembly. The connection assembly can include a booster hydraulic cylinder to dampen the pivoting of the booster; and an axle assembly comprising: a booster suspension frame; at least one axle; ground wheels provided on each axle; a booster suspension having at least one booster suspension air spring controlling the height of the booster suspension frame relative to the ground wheels; and a pressure regulator limiting the maximum pressure of a fluid supplied to the at least one booster suspension air spring.

The hybrid truck can have a cabin supported by a frame, the frame including two transversally spaced apart beams extending behind the cabin, a front axle bearing front wheels, a rear axle supported by the frame behind the cabin, the rear axle bearing rear wheels, a heat engine located in an engine compartment supported by the frame in front of the cabin, the heat engine drivingly connected to said rear axle; and an electric machine supported by the frame behind the rear axle, the electric machine being drivingly connected to the rear axle, and at least one battery electrically connected to the electric machine.

A foundation floor transport system for use in combination with a transport vehicle includes a frame that is sized and configured for selective coupling with a tongue adapter and an axle adapter, defining a transport configuration, wherein a tongue adapter attached to the tongue adapter is secured to the transport vehicle for transporting the frame; and wherein the tongue adapter and axle adapter may be selectively coupled to each other, defining a return haul configuration
