Abstract: A monorail conveyor system used to transport dishes to and from a dishwashing unit including a monorail mountable to a ceiling or a support frame, the monorail being of substantial length such as to form a loop traversing the entire dishwashing system. The monorail is hollow and mounted therein is a continuous chain supported by a plurality of wheels. A number of dish rack holders are each suspended from the chain by vertically extending bars which are pivotably attached to the chain conveyor so that the holder can tilt at a loading or unloading station. Guide wheels and an elongate horizontal track are provided to either support the holders in a horizontal position or permit them to tilt at the aforementioned stations. The guide wheels are preferably mounted at the bottom of the bars below the holders. The track is fixedly mounted and provides a horizontal force to each guide wheel.
