Abstract
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.
