About system7

The company, based in Laakirchen (Upper Austria), offers robust and durable machines as well as state-of-the-art technologies to meet the challenges in track construction and create an efficient and safe working environment.

One focus of system7 is the development and production of tamping machines. The tamping units of these machines plunge into the ballast bed with the tamping tines, compact it with the necessary high vibration forces, thus stabilising the ballast bed homogeneously and restoring the required track geometry.

Robust Master every challenge

The Austrian manufacturer's tamping machines are subjected to extremely challenging mechanical and climatic conditions throughout their years of operation. In order to guarantee the availability of the machines, all installed components must therefore be resilient and durable. A failure of the machines would not only be costly, but would also have a major impact on railway operations.

Up to 24 MDC3 cameras are used in system7's tamping machines. These are robust, durable and specially designed for extreme conditions. By using this modern technology, Liebherr offers a solution that meets the special requirements and challenges of track construction.

Track works are really challenging for all the components in our machines. In particular, they have to cope with strong vibrations, dust and temperature changes. The MDC3 camera deals with these demanding operating conditions in an exemplary manner.

Multicasting A must-have for efficient track construction work

Another challenge in track construction is that track-laying machines are equipped with several driving and working cabins, which are located at great distances from the work sites. It is important that relevant visual information is available in real time in all operator stands at the same time.

Therefore, the Liebherr camera offers an efficient solution. The so-called multicasting function of the MDC3 allows users to view identical video streams on several monitors simultaneously. This in turn provides more control and monitoring of different work processes.


Always sharp Clear view in any environment

For track construction, accurate and sharp images are essential to ensure work safety. However, difficult lighting conditions on the tracks can affect the quality of the images. Another challenge is that most of the track construction work takes place at night when there are fewer trains on the tracks. Therefore, it is important that the cameras provide detailed image information even in challenging lighting conditions.

The MDC3 camera solves this problem thanks to its high-performance imager and HDR technology, which provides detailed high-contrast images even in dark environments. Even in changing lighting conditions, the camera quickly adapts to the new environmental situation.

"Since the previous generation Liebherr camera has already proven itself after long-term use, our machines now benefit from the features and high image quality of the MDC3. A sharp image with many details facilitates image interpretation, and thus ensures greater efficiency and safety in operation," adds Harald Hüttmayr, head of automation technology at system7.

The high image quality and digital camera technology pave the way for further automations that make the use of the machine even more convenient and efficient. Of course, the low latency that we can achieve at this point with the MDC3 is also essential.

Automation The future of track construction work

For system7, the high image quality and digital camera technology pave the way for further automations that make the use of the machines even more convenient and efficient. The low latency of the MDC3 plays a decisive role in this.

What remains is the exciting question of what form automation will take in the future of track construction – and when.
