A conveyor mechanism for transporting trays utilizing a simple, single closed belt loop that is round in cross-section. The belt runs in and over a slider bed in straight sections and/or curved sections, and its upper edge extends above the slider bed so as to be exposed to the bottom of the trays whose weight gives the belt a frictional coefficient of engagement for transporting therealong. Line contact is provided between the transported trays and the topmost edge of the belt on which it is functionally balanced to limit the tipping motion of the load. The belt is kept operative by a motor, and guided in pulleys, slots or guides and guards, and thereby the load in effect "walks along the belt".
