  • Patent number: 6653578
    Abstract: Continuous, uninterrupted rails for trains and the like having weight measuring sections. Weighing ties replace normal ties under the rails in the weight measuring sections. The weighing ties are of the same height, width, and external contour as the normal ties. The weighing ties include weighing cells that can be laterally adjusted to accommodate various rail gauges. The weighing ties include a housing made of steel plate with a floor, sides, and a top with an opening therein. The weighing cells protrude through the openings in the housings to support the rails in the weight measuring section. Transverse force sensors are also provided in transverse holes in both ends of the weight measuring sections of the rails to determine the power shunt. The weighing cells and transverse force sensors are prefabricated and calibrated to improve accuracy and durability of the weighing cells and force sensors.

  • Patent number: 4811610
    Abstract: A weighing cell, in which the load introduced is measured by recording the tangential deformations of an annular deformation body which is supported freely on both sides and which is connected, by means of narrow annual webs acting as elastic joints, to the force introduction element on the one hand and to the force absorption element on the other hand, virtually no bending moments being transmitted in the region of the elastic joints and external disturbing forces having no influence on the weighing.
