ABSTRACT:
A dynamic weighing system for vehicles in motion which is specially adapted for weighing a plurality of coupled railroad cars of varying length randomly interspersed in a continuous coupled train. The system is adapted to automatically weigh and record each individual car in the train without the necessity of special grade slopes, special decoupling devices, mechanical switches, special positioning measurements, special axle measurements and counting and systems to screen out unwanted noises from irregular car movement. The inventive system in a preferred embodiment will not register locomotives and cabooses. The preferred system utilizes preselected photocell sensor units in an arrangement keyed to the cross section bulk of each car. The shape of the cars interrupts photocell signals at predetermined points on a weigh bridge, thereby actuating means at the precise point when each car is at the optimum weighing position on a scale.
