Rail Weighing Solutions

Rail weighing is crucial in industries where bulk material is either received or dispatched through rail route. From monitoring product deliveries to avoiding overloading penalties, rail weighing equipment play a vital role in productivity and profitability of such operations.

Some of the primary objectives for weighing rail wagons include:

• For rail operator (Indian Railways) & shipper/freight forwarders
  • Invoice freight charges based on verified weights
  • Data Integration with Railways FOIS system
  • Check overloading which can damage cars, wagons and rail infrastructure and lead to safety hazards & charge penalties

• For suppliers & purchasers – for weight verification and assessment of transit losses & pilferage
• For wagon / loco manufacturing & servicing
• For steel making industries – To measure process inputs/outputs in coke-charging car,  quenching car, scrap-car & ladle-car operations

Accuracy, reliability, maintainability and mode of operation are the primary criteria for selecting the right rail weighing product.

Types of Rail Weighing systems (based on mode of operation) -

Static rail weighbridge
In this type, normally a single wagon in weighed in static, coupled or uncoupled condition while positioned on pit-mounted weighbridge platform/s. Static rail weighbridges can have accuracy ranging from +/- 0.02% to 0.05%. Wagon Tippler weighbridge is a variant of static rail weighbridge which is incorporated in a wagon tippler, used for emptying bulk material from open-top wagons in to track hopper.   

In-motion weighbridge
In this type, a number of wagons in the form of a rake/train, are weighed dynamically while moving over –

• either a pair / set of special rails with embedded transducers for pit-less installation
• or a steel structure on load cells, for a pit-mounted installation

In-Motion rail weighbridge (also called Rail WIM system) can typically have accuracy up to +/-0.5% for wagons and +/- 0.2% for rake.

Although, in-motion weighbridges have more stringent site requirements and lower accuracy as compared to static weighbridges, they are often a preferred choice due to much faster weighing operation in order to avoid demurrage charges.
