Abstract
A system for bidirectional in-motion weighing of freight cars of a train includes a weighbridge, first and second sets of load cells, three wheel sensing devices, a control device, a device initiated by the control device for weighing operations, and a printer for the total car weight. The sets of load cells are mounted to receive the load from opposite ends of the weighbridge. Each set has a rapid change of output voltage when an axle enters or leaves the associated weighbridge end. The weighbridge is located between two spaced, aligned tracks and has a third track. The three tracks provide a path of train travel. Each wheel sensing device has a component to provide a signal when a wheel passes. Two components are mounted beside the first two tracks a predetermined distance from opposite ends of the third track. The third component is located beside one of the three tracks a predetermined distance from one end of the third track. The control device counts axles passing the first or second component, counts axles entering the nearer end of the weighbridge, and determines the number of axles of a car from the first coincident count of axles. The component of the third wheel sensing …
