Abstract: A transportation system including a guide way defining multiple surfaces, each extending at an angle to the ground and at least one track mounted on one of the surfaces. A vehicle is adapted for movement along the guide way and is adapted to engage a corresponding track on the one surface when the vehicle is moving along the guide way in one direction and is adapted to engage a corresponding track on another surface when the vehicle is moving along the guide way in another direction.

Abstract: A transportation system including two spaced parallel guide ways on which tracks are mounted for receiving vehicles. At least one beam extends between the guide ways for absorbing torsional forces caused by the composite centers of gravity of the vehicles being offset from the tracks.

Abstract: The specification discloses a transport system comprising a track including a horizontal top rail with a vertical web extending below the rail. A canted surface extends between one edge of the horizontal rail and the web. A support member extends angularly from the vertical web opposite the canted surface of the track. A transport unit is mounted on the track and includes motorized wheels rotationally supported on the unit for tracking along the surface extending angularly from the web. Counterbalance wheels are rotationally supported on the unit for tracking the canted surface of the track. The unit has its center of gravity outside the contact surfaces between the motorized and counterbalance wheels and the track and to the side of the web face on which the motorized wheels track. The transport unit is adapted to channel air between the underside of the main body of the unit and the horizontal rail of the track to lift the transport unit thereby relieving the loading of the unit on the track.
