More About Infinity In Motion Rail Scales

The Infinity Series rail scale system is one of the most effective and efficient weighing solutions available. If you are looking for an accurate, high quality rail scale solution that does not require you to shut down your operations during installation, does not require a concrete foundation, and costs less than a traditional weighbridge rail scale, the Infinity In Motion Rail Scale is perfect for your needs.

The Infinity is an assembly of steel rail ties that are equipped with weighing instrumentation and replace existing rail ties under the track. The scale system rests on a ballast, and in most cases does not require a concrete foundation.

The Infinity Series operates in traditional static weighing mode and unattended in-motion at speeds up to 50mph. Infinity is also the only in-motion rail scale system that is proven to be accurate and reliable on a curved track.
