Abstract: A conveyor system for trays, pallets and the like wherein the trays or other articles to be conveyed are supported at each side thereof by spaced parallel sets of rollers, one set comprising a set of drive rollers while the other set comprises idler rollers. The invention includes an arrangement for driving the drive rollers by an endless belt to provide a uniform drive speed of each of the drive rollers. The roller and drive arrangement permits the conveyor to be built in turning as well as ascending and descending configurations. The conveyor can be manufactured and installed in modular sections, each of which may have its own drive or may be driven from an adjacent section. An arrangement is disclosed for producing relatively sharp conveyor turns of any desired angle.
