A conveyor system for the transport of carriers such as trays in which the transport medium is two or more endless loops of round polycord, such as polyurethane belts, or cables, on which the trays are carried. In the drive system, the belts follow a figure-8 path and pass through the conveyor bed, are wrapped around a drive pulley driven by a reducer/motor, and return through the bed while maintaining continuous contact with the carriers. Corners on the conveyor bed are provided with mini-sheaves having partially open faces, around which the cables pass, the cables being of sufficient diameter to extend above the reduced diameter flange of the open-faced sheaves and remain in continuous contact with the bottom surface of the carriers.
