ABSTRACT:
Weighing of railway cars is accomplished by replacing a short section of fixed rail with a weigh-rail, and supporting the weigh-rail as well as sections of the fixed rail near the weigh-rail on an added foundation structure. The weigh-rail has a weigh-rail body for supporting the wheels of the railway car, and two dual shear beam load cells arranged transverse to the weigh-rail body. The weigh-rail is supported on the foundation structure solely by the four ends of the two dual shear beam load cells, and bumpers are arranged adjacent the ends of the load cells for maintaining the weigh-rail body aligned with the fixed rail ends. Bumpers are also arranged to prevent one end of the weigh-rail from flipping upwards when a railway car wheel enters the other end of the weigh-rail.
