ABSTRACT:
A conveying and storage system for wheeled pallets has tracks each formed by a pair of generally parallel rails. The pallet has grooved wheels at one side for riding on the upper edge of one rail and a roller on the other side for riding on the upper edge of the other rail. At the intersection of the tracks, the two wheel engaging rails are interconnected by a frog on which the peripheries of the grooved wheels roll. Where a wheel engaging rail crosses a roller engaging rail, the roller engaging rail is interrupted and elevated pads are provided that are coplanar with the upper edges of the rails. The pads are arranged to support the rollers as they negotiate the gap in the roller engaging rail.
