Patent ID: 8723059

Claim:
A system for weighing moving railcars, comprising: a scale disposed along the path of travel of the railcars to be weighed, the scale for providing multiple railcar weight readings and including first and second independent scale platforms over which travel wheel carriages of the railcars to be weighed; a distance between the first and second scale platforms, the distance between scale platforms being selected to minimize the time between weight readings; sensors on each scale platform, the sensors being actuatable by leading and trailing wheels of each railcar wheel carriage; and a controller having associated software and in communication with the scale, the controller adapted to use signals from the scale platform sensors to determine when a railcar wheel carriage is isolated on a corresponding scale platform, to capture an independent weight reading from the first scale platform only during a period of time when a trailing wheel carriage is isolated thereon, and to capture an independent weight reading from the second scale platform only during a period of time when a leading wheel carriage is isolated thereon, the weight readings from the first scale platform captured at a different time than the weight readings from the second scale platform, the controller further combining the independent and time separated weight readings from the first and second scale platforms to determine the weight of a given railcar.
