ABSTRACT:
A passenger conveyance vehicle loading and unloading ramp has one end pivotally supported adjacent a terminal building and the other end supported for movement into and away from a loading position at a vehicle door includes an enlarged generally cylindrical head mounted adjacent the outer end of the ramp for limited pivotal movement about a horizontal axis extending transversely of the longitudinal axis of the ramp, and a cab or vestibule mounted on the enlarged head for movement therewith and for pivotal movement about a generaly vertical axis for contact with the vehicle throughout a wide range of angles between the longitudinal axes of the ramp and of the conveyance vehicle. The vestibule is supported entirely from its bottom portion whereby the vestibule structure may be relatively lightweight since only minimal loads will have to be transferred between the top and bottom of the vestibule structure.
