LEVEL PRO – on the road to success with a unique levelling system

Ultra-precise milling results

WIRTGEN has developed an ultra-precise proprietary levelling system that includes a software programmed specifically for cold milling machines – LEVEL PRO. The overall system comprises the clearly structured LEVEL PRO panel, a controller and multiple sensors. A wide variety of different sensors, such as milling depth, cross slope or ultrasonic sensors, can be integrated into the automatic levelling system.

The graphics-enabled LEVEL PRO panel provides a clear readout of key parameters. For example, the set and actual values of two active sensor signals and one passive sensor are continuously displayed on the screens as work progresses. An additional milling depth indicator on the screen - showing the difference between scraper blade and side plate positions - enables convenient monitoring of the actual milling depth. In addition, the memory feature is extremely useful to pre-programme, store and retrieve set values.

Ensuring a perfect start of the milling operation

The innovative automatic system initiating the milling process enables the machine to mill at the maximum depth of 330 mm right from the very first metre. When the automatic levelling system is activated, the machine is lowered automatically at maximum speed together with the rotating milling drum. Once the side plates reach the ground, the lifting columns continue lowering in slow mode; the lowering rate is adjusted further in the milled cut if required. The machine retains its parallel alignment – no time is wasted on complex manual lowering processes.
