Our Accurate In-Motion Train Weighing System is Designed to Enhance Safety & Optimise Efficiency
In-Motion Weighing for Rail Freight Terminals
Also known as Weigh-in-Motion or Dynamic Weighing Systems, this application consists of a single Portable Train Weigher (PTW) installed on the track.
Our In-Motion Train Weighing System offers a fast, efficient, and reliable method for dynamically weighing trains at speeds of up to 3 mph (5 kph). This innovative solution is ideal for the rail freight industry, enabling terminals to continuously monitor train weights and ensure compliance with strict weight limits. Additionally, it serves as a powerful tool for various freight sectors by identifying potential issues, such as overloading, and helping operators reduce risks, thereby improving overall efficiency.
Since its launch in 1997, the PTW has undergone rigorous testing and proven its ability to withstand some of the most challenging rail environments, consistently delivering accurate and reliable results. Thanks to its portable design and straightforward installation, operators can start collecting critical weighing data in just 15 minutes, all without disrupting regular train movements.
Key Features of Our In-Motion Train Weighing Systems
Quick Setup
The PTW can be installed in under 15 minutes without interfering with scheduled train movements. Additionally, the in-motion rail scale is compatible with a wide range of track gauges and rail profiles, making it highly adaptable for various locations.
Heavy-Duty Capacity
Designed to withstand heavy loads, the PTW can weigh up to 40,000kg per axle, making it suitable for demanding freight applications. Its proven performance meets the needs of both short-term and long-term freight projects.
Hassle-Free Install
There’s no need for permanent modifications to the track. No cutting, drilling or welding is required. Furthermore, the PTW installation requires no foundations, making it easy to install without affecting existing track infrastructure.
Flange-Friendly Design
Our latest patented design incorporates a smoother transition onto the weighing system. This improvement enables a more consistent weighing operation while providing enhanced protection to your rolling stock wheels.
Why Choose In-Motion Weighing?
Accurate Weight Measurements
Our advanced system accurately measures the total weight of a train. In addition, our software and indicator interfaces provide detailed information on wagon, axle and wheel weights.
Cost Effective
Avoid the high costs associated with installing and maintaining fixed train weighbridges. Instead, our system’s easy setup offers a more affordable and flexible solution for rail freight terminals.
Enhance Safety
By accurately monitoring a trains weight, our system can help avoid overloading, which in turn reduces the risk of derailments and protects freight wagons as well as rail infrastructure.
