Rail Weigh-In-Motion (Rail - WIM)

Rail Weigh-In-Motion is our RDSO approved, tailor-made, train weighing system that is easy to install at low installation cost. Our specialist team develops & provides solutions for all rail users, from, raw material procurement to end users. icroprocessor based modular electronics and high quality strain gauges from USA ensure high accuracy even at varying speeds. The system can be designed for static and/or in-motion weighing of wheels, axles and bogies and for full dratt weighing of locomotives and all types ol rolling stock.

Rail-Wltvt provides precision data on rack and wagon weights that can be interlaced with client's business systems via PC’s, Ethernet or Internet.

By automatically detecting wheel, axle and wagon overloads the system helps to identity imbalanced loads and avoid multiple weighments of the same vehicle ensuring safety and avoiding overloading penalties.
