ABSTRACT:
A guideway system for cargo including vehicles is provided wherein a carriage glides on a rail mounted in a channel. The rail has compressed air discharge ports and vacuum intake ports positioned longitudinally therealong. The compressed air ports emit sufficient air to provide an air support cushion under the carriage and to impart positive air pressure behind it while the vacuum ports reduce the air pressure forward of the carriage to create an air pressure differential that propels the carriage along such rail. Vehicles drive onto a carriage, are secured in place and are conveyed to a desired station on such carriage. The vehicle then unloads from the carriage and drives off to its final destination. Similarly, other cargo is loaded onto a carriage and unloaded at its destination.
In another embodiment, the carriage has a longitudinal slot in its underbody adjacent its support rail and compressed air is discharged from ports in the rail at the forward portion of the slot to propel the carriage along the rail.
