Portable or Mobile train weighing, was a Swedish invention, Patented in 1973. This took the form of a 4 load cell platform that weighed the wagons on the wheel flange and not the wheel tyre. As the wagon went along the rails, a built in ramp simply lifted the flange and wheel and guided the flange onto the scale. The main objective was and still is to have a weighing device, that was as accurate as a static weighing system (weighbridge), had mobility, (achievable, by weighing on the wheel flanges), plus no foundation or track alterations whatsoever.
Our AX Series has all these attributes, plus it is probably the most accurate system on the market today. We use just two specially manufactured load cells, built into a frame with built in ramps to weigh the wheel flanges. There can be 1 base unit, or multi- base units running in tandem depending on the accuracy required. We can achieve remarkable accuracy down to less than 0.01%. The AX Series can be used dynamically or static, depending on the customer’s requirements. All weights are retrieved for wheel, axle, bogie and wagon. These weights can be used for safety analysis, exact centre of gravity, wheel and chassis alignment, and weights of goods, plus many other requirements. Mobile Train Weighing has come a long way since 1973.However the flange weighing method of establishing the load, is just the same. Except we can now weigh Individual Wheels, whereas the Original system was just Axle weights.
