The invention concerns a method for managing the load of a vehicle (C) of the type of that equipped with at least one module for transmitting data (110, 120, 130) through radiofrequency signals (F1, F2, F3) and one module for receiving (120, 220) data from the transmission module, said vehicle (C) and the different modules being disposed so that the load, once present, has an impact on the propagation of the radiofrequency signal, remarkable in that it comprises the following operation: detection of the variation of the spectral signature of the signal received (F2′) by the receiving module (120, 220), in order to detect variations, in particular corresponding to the presence and/or absence of a load (600).

The invention also concerns the device enabling said method to be implemented.

Applications: managing the load of a vehicle.

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.

An upper coupler assembly for use with a trailer includes an apron assembly and a grid assembly coupled with the apron assembly. The apron assembly is arranged to engage a coupling of a vehicle to cause the coupling to be aligned with the grid assembly when the upper coupler is being coupled with the vehicle. The grid assembly couples the upper coupler assembly with the coupling of the vehicle.

A cargo trailer includes a plurality of walls defining a cargo area, the walls including a front wall facing a rear of a tractor when the cargo trailer is coupled to the tractor. A recessed cavity is provided at a forward side of the front wall. A plurality of utility line connectors are positioned at least partially within the recessed cavity for establishing connections between at least one utility source of the tractor and at least one utility component of the cargo trailer. The plurality of utility line connectors are spaced vertically above a bottom wall of the recessed cavity. A raceway has an upper end situated on the bottom wall and a lower end situated at a height below the cargo area. The raceway defines an interior tunnel receiving a plurality of utility lines connected to the plurality of utility line connectors, the interior tunnel sealed from cargo area.

A high density mobile power unit may include an elongated unibody frame having a frame cavity, a front end, a rear end, an elongated roof panel, a front panel, a rear panel, an elongated floor assembly having an upper side and a lower side, an elongated first side panel, and an elongated second side panel. A frame cavity bounded by the roof panel, front panel, rear panel, the upper side of the floor assembly, first side panel, and second side panel. A plurality of wheel and tire assemblies may be coupled to the unibody frame and may support the unibody frame above a ground surface. A radiator may be coupled to the upper side of the floor assembly and positioned within the frame cavity at the front end. At least one generator may be positioned within the frame cavity at the rear end. An engine may be positioned within the frame cavity between the at least one generator and the radiator. An under carriage structural lattice arrangement may be coupled to the lower side of the floor assembly.

A heavy load transport vehicle of variable width has a chassis which has two chassis parts which each support a number of wheel arrangements arranged one behind another, wherein the two chassis parts define a transport platform for the heavy load to be transported. The transport vehicle may have a wheel-free central chassis part arranged between said two lateral chassis parts, and that at least one lateral chassis part is pivotable about a pivot axis in relation to the central chassis part.

A trailer assembly suitable for carrying a container of proppant has a frame with a first side rail and a second side rail extending in generally parallel relation to each other and a plurality of wheels rotatably mounted below the frame. The frame has a plurality of cross members extending between the side rails. First and second outriggers extend across the side rails so as to each have one end extending outwardly of one of the side rails and an opposite end extending outwardly of the other side rail. The first and second outriggers are suitable for receiving the container of proppant thereon. The frame has a first section positioned above the wheels and a second section positioned at a level lower than a level of the first section. The proppant container is placed on the first section.
