There is an option of using static or dynamic weighing methods. The invaluable advantage of this system is that the scale is taken to the weighing location, rather than the other way round where the wagon or train is taken to the scale, which results in enormous savings in terms of both time and money.

The system is installed and removed in the same way as the LARS-m system. The process is very easy and takes just a few minutes. No special tools are required for this purpose.

The measurement is taken on the wheel flange. This means that faults related to the running surface are ruled out from the outset, such as faulty grip due to conical wheels and effects caused by the linear expansion of the rail.

The LARS-dyn weighing system consists of a robust steel construction and inner tensioning element with locknuts. These are used to fasten the measuring system inside the rails, ensuring that it stays securely in place, even over relatively long periods of time. The height of the wheel flanges can be adjusted with shim plates without the need to remove the scale. The LARS-dyn system can be fitted in virtually any type of rail. The weighing system is "deactivated" by removing the wear covers above the measuring bridge. Vehicles can run over it at relatively high speeds in this state.

The LARS-dyn weighing system is supplied ready calibrated, obviating the need for any time-consuming and expensive adjustment on site.
