A mounting device for a support unit for commercial vehicles includes at least one supporting area, a first fixing area and a second fixing area, wherein the supporting area is configured to absorb the supporting forces in the supporting direction from the support unit or a support tube, wherein the first fixing area and the second fixing area are configured to fix the mounting device to a semi-trailer, wherein the first fixing area has at least one hole, wherein the second fixing area has at least one hole, and wherein the holes are configured to receive a fastener.

A vehicle built-in electric jack system, including a plurality of electric jacks capable of lifting a vehicle. The plurality of jacks operates using a 12-volt power supply. The plurality of jacks are telescopic jacks. Each jack is made from a plurality of cylinders. The cylinders are apportioned such that each cylinder for a jack fits inside of the previous cylinder. Each of the plurality of jacks has a minimum of one light placed on the jack. The light is directed toward the wheel well of the vehicle. The jacks and lights are attached to a controller. The controller is located inside of the vehicle such that the jacks and lights can be operated while the user is inside of the vehicle cab. Further, each jack has a rocker switch located thereon that can control the jack to which it is attached.

A transportable fold-out at least partial enclosure includes in one aspect of the invention a stationary platform having a major surface defining a stationary plane, a plurality of side edges, a front edge and a back edge. A primary platform has a major surface defining a primary plane, an inside edge, an outside edge, a front edge, a back edge, the inside edge being joined to the stationary platform, the primary platform having a folded position in which the primary plane and stationary plane are oblique or orthogonal, and the primary platform having an extended position where the primary platform is unfolded from the stationary platform. An end wall assembly has at least two segments, each segment having a major surface defining a segment plane, side edges, a top edge and a bottom edge, the side edges of the segments being joined to each other, the bottom edges of each segment being joined to one of the stationary platform and the primary platform. The end wall assembly has an extended position in which the segment planes are at an angle to form a wall to both the stationary plane and the primary plane, and the end wall assembly having a folded position. At least one actuating mechanism is joined to at least one of the segments and the stationary platform or the primary platform to which said at least one of the segments is joined, said at least one actuating mechanism configured to provide a force to urge said at least one of the segments to the extended position.

The technology relates to autonomous vehicles having hitched or towed trailers for transporting cargo and other items between locations. Aspects of the technology provide a smart hitch connection between the fifth-wheel of a tractor unit and the kingpin of a trailer. This avoids requiring a person to make physical pneumatic and electrical connections between the fifth-wheel and kingpin using external hoses and cables. Instead, the necessary connections are made internally, autonomously. For instance, the fifth-wheel may provide air pressure via one or more slots arranged on a connection surface, and the trailer is configured to receive the air pressure through one or more openings on a contact surface of the kingpin. An electrical connection section of the fifth-wheel may also provide electrical signals and/or power to an electrical contact interface of the kingpin. Rotational information about relative alignment of the trailer to the tractor unit may also be provided.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A hitch receiver stand comprises a hitch receiver assembly having a hitch receiver than can removably mount a device having a standard hitch and is removably attached to a framework. The framework may include a number of releasably coupled components.

Embodiments of the present disclosure include a trailer assembly for transporting a plurality of proppant containers along a roadway, and associated methods. The trailer assembly includes a skeletal frame having open areas between structural components to enhance weight reduction of the frame, and first, second, third, and connector sections. Additionally, the frame includes a pair of spaced-apart side rails and three or more wheel and axle assemblies to facilitate movement of the trailer assembly. The trailer assembly includes a first pair of outriggers coupled to and arranged transverse the pair of side rails, and a second pair of outriggers arranged proximate the first pair of outriggers. The outriggers have a coupling element positioned at each distal end to engage and secure a proppant container of the plurality of proppant containers to the trailer assembly. Each distal end is positioned to extend outwardly from an axis of the trailer.
