AMTAB WIM – Dynamic Rail Scale with Outstanding Operational Reliability

The AMTAB WIM railway scale offers an innovative solution for weighing moving train sets. This dynamic scale not only provides the weight of the trains but also several other data acquisition possibilities, thus meeting all requirements. Its installation is fast and seamless, taking only three working days without altering the existing infrastructure. The system boasts outstanding measurement accuracy, guaranteeing the best operational reliability. The WIM function offers the highest level of operational reliability and is continuously improvable for wheel defect detection based on a neural network. AMTAB provides more than 15 years of warranty on its products, offering a long-term, reliable solution to its customers. The system can also be flexibly integrated with other systems, which facilitates data processing. Choose AMTAB WIM to ensure the most accurate measurements and the best operational reliability in rail transport!

THE AMTAB SOLUTION

AMTAB offers unique solutions with its in-house developed dynamic railway scales. The specific design of the equipment provides several other data acquisition possibilities beyond the weighing of moving train sets.

Installation and commissioning are completed within three working days. No modification of existing infrastructure is required; installation takes place without interrupting traffic. Both the system and its sensors have certification for operation under all climatic conditions and fit onto all standard rails. The system possesses one of the best measurement accuracies in the world in the category of dynamic weighing scales.

Our concept represents the best price-to-value ratio on the market. AMTAB guarantees 15 years of system operation.

SENSORS

• All types of railway vehicle performs its measurement at a speed range of 1 – +140 km/h.
• In addition to the extremely high operational reliability , the system's average repair time (MTTR) is less than 1 hour.
• The AMTAB WIM offers the highest operational reliability on the market, with an average time between failures (MTBF) of more than 90,000 hours.
• The system is delivered with a built-in wagon classification function .
• Our data can be easily integrated with superior and/or parallel systems (MySQL data structure).
• The system is excellently suited for detecting wheel defects, moreover its deep learning-based neural network continuously improves system performance.
• Issued by the Research Institutes of Sweden (RISE – an organization approved in more than 100 countries) calibration certificate (in accordance with OIML R 106 standard) certifies that the sensors' accuracy is better than 0.1% in the 3–30 metric ton/axle load range, at ambient temperatures between -25 °C and +40 °C.

ON-THE-MOVE MEASUREMENT

On-the-move measurement is our absolute core competence. The system was originally developed for this purpose (30 years ago), and over the years it has undergone significant development through.

There is a huge industrial demand worldwide for this technology, and although customers – quite rightly – focus on the accuracy of the system when purchasing it, it is clear that ultimately the system's reliability and durability (long lifespan) are what they value the most.

WHEEL DEFECT DETECTION

In addition to measuring all weight variations of train sets, the AMTAB WIM also detects damaged wheels (WDD) as well as senses and warns of an increased derailment risk..

The latter function is most effective at speeds above 35 km/h, as the system detects numerous anomalies and irregularities as dynamic forces. The two main wheel defects, including wheel flat spots and the ovalities, are detected by the system alike.

The AMTAB WDD system on artificial neural networks (deep learning) is based, thanks to which the system continuously improves its detection capabilities throughout its entire lifetime.

AMTAB WIM NETWORK

When the AMTAB WIM is installed at multiple points in the railway network, the data can easily be consolidated into a „Railway Logistics Center”, and as a Maintenance and Logistics Supervision System can be used.

This approach is already quite advanced in a EU-funded railway project, to which AMTAB contributes with its systems.
