Abstract

A modular, electrified monorail system upon which at least one motorized trolley assembly may be propelled along. The system may incorporate a plurality of rail assemblies adapted to be coupled adjacent to one another to form a generally continuous track. Each rail assembly may make use of an electrified track adapted to provide an electrical signal from an electrical power source to at least one electrical conductor extending coextensively along the electrified track. A controller may be mounted on the electrified track. The controller may be configured to selectively apply and remove the electrical power from the electrified track to control propulsion of the motorized trolley assembly along the electrified track.

5. The system of claim 1, wherein the at least one sensor comprises:

a plurality of first sensors, each said first sensor being positioned adjacent a longitudinal edge of an associated one of the electrified tracks, and each said first sensor being in communication with the controller of its said associated electrified track, for informing the controller of an arrival of the motorized trolley on its said associated electrified track; and

wherein the first sensor and the second sensor on each said electrified track are located such that the first sensor is upstream, relative to a direction of travel of the motorized trolley, of the second sensor.

6. The system of claim 5, wherein the controller on said associated electrified track communicates information to the remotely located controller, based on signals from the first and second sensors, that the remotely located controller uses to inform an immediately upstream one of the electrified tracks that said associated electrified track is free to receive another one of the motorized trolleys.

7. The system of claim 1, wherein the at least one electrical conductor comprises an electrical bus bar.

8. The system of claim 1, wherein the at least one conductor comprises a control bus bar for carrying control signals to each of the controllers on each of the electrified tracks.

9. The system of claim 1, wherein the at least one electrical conductor comprises a plurality of electrical bus bars extending generally parallel to one another along a surface of the electrified track, and adapted to make physical contact with a portion of the motorized trolley to thus transfer electrical power from at least one of an AC power source or a DC power source to the motorized trolley to propel the motorized trolley along the electrified track.

10. The system of claim 1, wherein the rail assembly further includes at least one hanger for supporting the electrified track from an external support beam.

11. The system of claim 1, wherein the system further includes the motorized trolley, and wherein the motorized trolley includes structure for making electrical contact with a portion of the electrified track without impeding movement of the motorized trolley.

12. The system of claim 11, further including:
