An improved articulated heavy haul trailer combination comprises a trailing accessory vehicle such as a booster coupled to a main trailer by a coupling. The coupling includes a horizontal hinge, a vertical hinge that allows the trailing accessory vehicle to yaw in a horizontal plane, a spreader extending between the hinges and a hydraulic piston and cylinder. A turn sensor mounted on said combination detects yawing, and a controller reduces the piston and cylinder's downward biasing force on the coupling.

A couplable automotive road vehicle includes two front wheels, a chassis having a front part and a rear part, an articulated connection device, and front and rear couplings. A wheel cylinder is defined as the cylindrical geometric shape surrounding the two front wheels when the wheels are not turned. The front part of the chassis includes a chassis beam disposed behind the front wheels, outside the wheel cylinder. The front coupling includes a yaw rigid coupling module mounted on the chassis beam between the two front wheels. The vehicle includes, for each front wheel, a suspension arm mounted on the chassis beam and extending around the wheel cylinder, above same, and a tie rod for controlling the steering device, located above the wheel cylinder.

An arrangement for improving manoeuvrability of a vehicle combination that includes a first vehicle unit, a second vehicle unit and a third vehicle unit interconnected by articulated joints, where the vehicle combination includes two driven axles and where each driven axle can be controlled independently, an arrangement for determining the articulation angel between the vehicle units, an arrangement for determining a steering wheel angle of the vehicle combination, an arrangement for determining the speed of the vehicle combination, an arrangement for determining the yaw rate of the vehicle units, and an arrangement for determining a delay value between the steering wheels of the vehicle combination and at least one articulated joint, where the arrangement is adapted to control a desired articulation angle of the articulated joints by coordinating the force ratio between the two driven axles by using the determined yaw rate of the vehicle units and the determined delay value.

Connected tractor and trailer identifications and the order of hook-up of multiple trailers to a tractor is are determined by identifying trailer VINs using a PLC system and eliminating Bluetooth signals that do not broadcast trailer VINs that match the PLC system. A tractor-based Bluetooth trailer order and a trailer-based Bluetooth trailer order utilizing RSSI value strengths are determined. The trailer order is set if the tractor-based Bluetooth trailer order matches the trailer-based Bluetooth order. If the order does not match, a RSSI value weighting process is used to choose between the tractor-based order and the trailer-based order.

A trailer including a hydraulic steering system includes: a trailer body; a plurality of axles connected to the trailer body; a steering cylinder connected to at least one axle of the plurality of axles and configured to turn the at least one axle; a sensing cylinder; a controller; and a hydraulic steering system. The hydraulic steering system includes a hydraulic circuit including a plurality of hoses and valves, and the steering cylinder is in fluid communication with at least one of the sensing cylinder and the controller. The hydraulic steering system is configured to transition between: (1) an automatic steering mode and (2) a manual steering mode. A towing system and a method of steering a trailer are also disclosed.

The invention relates to a device comprising a stationary transfer station (3) and a trailer train (1) comprising at least one trailer-train trailer (2), for transferring loads (L) from the trailer-train trailer (2) into the stationary transfer station (3), the trailer-train trailer (2) being provided with a continuous conveyor (25) driven by a motor (27), for receiving the load (L). The motor (27) of the continuous conveyor (25) of the trailer-train trailer (2) is powered by a battery (6) of the trailer train (1). Another continuous conveyor (30) driven by another motor (32) is arranged in the transfer station (3), for receiving the load (L), the other motor (32) of the other continuous conveyor (30) being powered in the transfer station (3) in a pre-determined handling position by the battery (6) of the trailer train (1).

In one example, a mother cart is provided that is suitable for transporting a daughter cart. The mother cart includes a base frame having a group of wheels configured to allow the mother cart to be moved. The base frame, in turn, includes a loading bay for receiving the daughter cart, and a support surface for supporting the daughter cart. Finally, the base frame includes a primary restraint mechanism for engaging and securing the daughter cart in the loading bay.

The present invention relates to a vehicle, which is used in particular for transporting objects, in particular workpieces. Here, preferably one or more sensor devices are provided, by means of which in particular a region surrounding the vehicle is detectable.

A propulsion arrangement for a self-powered dolly vehicle unit, the propulsion arrangement comprising a first electric machine, a second electric machine, a gearbox, and an open differential for driving first and second wheels of a driven axle, wherein the first and second electric machines are arranged in parallel and connected to the open differential via the gearbox at respective gear ratios.

The present invention relates to a transport wagon consisting of a base frame, wherein the base frame comprises a rotatable bogie assembly on its front side for attachment to a powered tow or push truck and comprises one or more front steering wheels placed on the front side of the base frame and one or more rear steering wheels placed on the rear side of the base frame, wherein the one or more front steering wheels and the one or more rear steering wheels are coupled in such a way to the rotatable bogie assembly, that in operation the one or more front steering wheels rotate along with the rotatable bogie assembly and that the one or more rear steering wheels rotate in opposite direction with respect to the rotatable bogie assembly, wherein the base frame comprises at least one longitudinal beam to which a front cross beam, a rear cross beam and at least one intermediate cross beam are arranged with intermediate spaces, wherein at least one intermediate space is arranged for receiving goods, wherein an intermediate wheel suspension with two or more intermediate wheels is arranged under one or more of the intermediate cross beams. The present transport wagon provides a transport wagon that remains well steerable on uneven floors.
