Resource-saving technologies for recycling and soil stabilising
The satellite-based AutoTrac steering system used in Wirtgen WR-Series recyclers makes precise and efficient project processing easier. It steers the machine accurately within tolerances of a few centimetres on the basis of a previously calculated reference strip and a specified overlap of adjacent strips, enabling consistent utilisation of the machine’s ideal working width. This results in greater process efficiency and therefore a higher degree of environmental compatibility.
The Wirtgen Performance Tracker is also available with WR-Series machines. The system balances all relevant working parameters on a site-specific basis to provide a comprehensive database for construction site analysis and documentation. For soil stabilising projects, this includes working width and depth, area and distance worked, fuel consumption, and much more.
Non-stringline control increases efficiency and safety
The AutoPilot 2.0 is a control system developed by Wirtgen for non-stringline paving as an alternative to conventional scanning along a stringline. The system, which precisely controls both the machine’s height adjustment and steering, is available for all offset pavers and placers/spreaders. A GNSS signal and, depending on the configuration, various local sensors, such as an ultrasonic sensor on the machine, act as a reference. The stringline is completely eliminated and, with it of course, the time needed to set it up and take it down. It also enables fast and precise paving of tight radii and complex geometries. The Wirtgen AutoPilot 2.0 system provides machine control and remote control from a single source.
