  • Patent number: 4640459
    Abstract: This invention concerns dual rail transportation system (1) used with roller pallets on which the wheels (2) of at least one pair of wheels are swiveling. On the margins of the running surface (5) of one rail (4) have been provided relatively low steering flanges (6) with a spacing (a) nearly the same as the breath (b) of the wheel traveling thereon. The other rail has a flat running surface sufficiently wider than the surface (5) of the one rail (4) to permit swiveling of the wheel traveling thereon. The roller pallet will hereby be steered with high accuracy on the rails.
