A vehicle body including opposite side and end peripheral skirt portions which project at least slightly downwardly below a central underportion of the body in order to define a downwardly opening central chamber. Longitudinally spaced portions of the side walls of the body include horizontal openings formed therethrough adjacent the lower extremities of the side walls and opening into longitudinal air plenums defined within the side walls. The plenums open downwardly and inwardly into the opposite sides of the central chamber and axial intake driven blower wheels are supported within the air plenums in registry with the inner ends of the horizontal openings and are operative to draw ambient air into the air plenum chambers from the exterior of the body through the horizontal openings for subsequent discharge downwardly and inwardly into the central chamber, whereby a vehicle supporting air cushion is formed in the central chamber. The blower wheels include peripheral load supporting tread portions and are vertically shiftable between upper and lower positions spaced above and lowered into rolling contact with a vehicle body supporting surface disposed beneath the vehicle body and along which the body is to be moved.
