What should be the distance of the lower edge of the Skimmer from the railhead?

In accordance with the regulations concerning the technical conditions of rail vehicles, the track clearer visible in the picture must be mounted at a strictly specified height. The bottom edge of its active surface should be no higher than 100 mm above the rail head. This positioning ensures the effective removal of any potential obstacles from the track, while preventing the track clearer from striking the rail or other infrastructure elements.
