ABSTRACT:
A trailer is described, whose bed is controllably adjusted in height to facilitate the loading, transportation and unloading of truck tractors and truck units. The trailer is provided with a kingpin to couple with a 5th wheel of a truck tractor having a compressed air-braking system. The trailer bed slopes downwardly, and terminates in a further downwardly sloping ramp section onto which the front or rear wheels of the vehicle to be transported is brought to move in being placed onto the trailer bed. An actuable switch is provided to cooperate with the air-braking system in filling an expandable air bag with the braking system's compressed air when it is desired to raise the trailer bed, or to bleed the compressed air therefrom when it is desired to lower the bed.
