ABSTRACT:
A fairing attachable beneath a lower, outer longitudinal edge of a trailer. The fairing has longitudinally extending forward and rearward sections. The rearward section can be moved longitudinally to adjustably locate its rearward edge in a selected position forward of the trailer's wheel assembly. Such adjustable positioning occurs automatically if the rearward section is coupled to and longitudinally movable with the support frame for the trailer's wheel assembly, thus maintaining the rearward edge of the fairing in the selected position whenever the trailer's wheel assembly is longitudinally adjusted relative to the trailer. A hinge mechanism coupled between the trailer and the fairing allows pivotal displacement of each fairing section between lowered and raised positions. The lowered position is for long distance haulage of the trailer in order to achieve fuel economy. The raised position is for situations in which the trailer must be manoeuvred over ramps, uneven terrain, etc. which might contact the underside of or otherwise interfere with the fairing.
