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:
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 this type, a number of wagons in the form of a rake/train, are weighed dynamically while moving over –
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.
