Abstract:
A trailer converter dolly includes a frame bearing a fifth wheel supported by a suspension mechanism, an axle assembly, and a wheel assembly. A drawbar housing secured to the front of the frame moveably receives a drawbar which is configured to move toward and away from a leading truck or trailer, thus adjusting the distance between the towed trailer attached to the trailer converter dolly and a leading truck or trailer. A speed sensor determines the speed of the trailer converter dolly and provides one or more signals relating to the speed of the trailer converter dolly. An automatic adjusting mechanism associated with the moveable drawbar moves the drawbar in response to the one or more speed signals provided by the speed sensor.
