A rotatable trailer bed includes a frame, a trailer bed, a turntable swivel assembly, and a plurality of swivel casters. The frame includes a bed section, a hitch section, and two wheel sets. The hitch section is adjacently connected a front end of the bed section. The two wheel sets is rotatably mounted to the bed section. The plurality of swivel casters is mounted to the bed section is perimetrically positioned around the bed section. The trailer bed is rotatably mounted to the bed section through the turntable swivel assembly as the plurality of swivel casters maintain the balance and level of the trailer bed.

A waste removal system with a trailer for the storage of materials such as waste or rubble, wherein said trailer has a front wall a rear wall and plurality of side walls with an extended slope on at least one of said walls to increase the volume capacity therein. The trailer may additionally contain a slanted access door or ramp which alternatively raises and lowers, allowing for ease of ingress and egress of the trailer volume. The waste removal system may additionally include a transport vehicle with a grappler mounted at a distal end of a boom, wherein said grappler grasps waste and deposits said waste into the previously-mentioned trailer for transport to and from a desired location.

A trailer neck reinforcement structure includes a first beam reinforcement structure including: (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. A second beam reinforcement structure 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 the first and second beam inner inserts. A first group of external cross members is located between the first beam outer insert and the left side rail, and a second group of external cross members is 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.

A tractor trailer monitoring system includes a network having a server and a database; a first computing device; a monitoring platform to be accessible from the first computing device; a tractor trailer system, having a tractor unit; an air supply control system to control air supply to a brake system of the trailer, the air supply control system having a CPU to receive commands from the first computing device; the first computing device and monitoring platform are to receive an identifying code from a user to activate air supply to the brake system of the trailer.

A louvered sidewall cargo container assembly for reducing crosswind exposure includes a cargo container, which is substantially cuboid shaped and comprises a pair of sidewalls, a front, a back, a bottom, and a roof. Each sidewall comprises a plurality of louvers. An actuator is engaged to the cargo container and is operationally engaged to each of the plurality of louvers. The actuator is positioned to selectively motivate each of the louvers between a first position a second position. In the first position, the louver is substantially perpendicular to the bottom and each of the plurality of louvers is in a closed configuration. In the second position, the louver is transverse or parallel to the bottom, extends into the cargo container, and each of the pluralities of louvers is in an open configuration. In the open configuration, the pluralities of louvers allow passage of a crosswind through the cargo container.

The application relates to carriage of goods by public roads. A freight handling apparatus includes a frame having a coupling mechanism for coupling to a motor vehicle, a container-carrying deck, a wheel suspension, an outer body in the form of a rectangular freight container, the inner space of the outer body being divided in horizontal direction by a plate to accommodate in the lower freight compartment a reusable tank with necessary control and measurement equipment, filling and drain fittings. The freight handling apparatus simplifies and secures its transportation on roads as much as possible by lowering the center of gravity and arrangement of the center of gravity of the tank close to the axis of the vehicle carrying the apparatus, facilitates maintenance and inspection of the tank without removing it from the frame, and makes easier loading and unloading of goods.

A trailer having a hitch assembly, a deck assembly, an axle assembly and a structural joint positioned between the deck assembly and the axle assembly is provided. The deck assembly having a first support beams and a second support beams supporting decking. The first support beam and the second support beam can have a positive camber. At least one shim plate can be rotatable between a joint position, wherein the at least one shim plate is positioned in the structural joint, and a storage position, wherein the at least one shim plate is rotated out of the structural joint to adjust the amount of camber in the support beams.
