Wirtgen’s new WR series can be used for various applications, from cold recycling to the stabilisation of a wide range of construction materials, in processes such as soil stabilisation or consolidation in road construction. This new series will be available around the world from mid 2025.
The compact dimensions and low machine weight of the WR 200 X make it easy to transport from place to place. The WR 240 X strikes a perfect balance between machine performance and weight to assure high daily productivity. The WR 250 X is the most powerful machine of the WR series and delivers the highest productivity.
The three models have working widths of up to 2,400 mm, with engine power outputs of between 305 and 571 kW (depending on the model). The improved Duraforce milling and mixing rotor enables consistently high mixing quality and productivity under all working conditions and contributes to the minimisation of fuel consumption, CO2 emissions and wear.
Improved operating concept
The most important aspect of these new cold recyclers and stabilisers is their revised and enhanced operating concept. A new multifunction joystick, fingertip control and ergonomic height adjustment via the multifunction armrest ensure maximum ease of use. In addition to digital process monitoring, the large machine control panel features application-relevant displays and the Wirtgen Group CoPilot. This digital assistance system helps operators to exploit the full potential of their machine, provides suggested courses of action during the work in progress and offers interactive tutorials.
The tutorials help operators to familiarise themselves with the machine and its functions. Explanations of the steering modes, the features of the multifunction joystick as well as transport and safety instructions are also provided. Operators are offered visualised recommendations for action and their effect while interacting directly with the machine. The system guides operators step by step through each scenario, detects their input commands and the machine status and then automatically proceeds to the next process step.
Digital solutions for higher efficiency
The AutoTrac steering assistance system steers the machine accurately on the basis of a previously calculated reference strip and a specified overlap of adjacent strips. The Automatic Reverse function enables rapid reversal of the travel direction at the press of a button.
With the Mix Assist digital assistance system, various automated functions can be individually configured and conveniently initiated simply by pressing a button. It also allows operators to set up and save a sequence of working steps as an automated process for later use when needed. When using this, the system rearranges the camera images displayed to set a focus on the currently relevant working area. This reduces the operator’s workload and simultaneously improves machine productivity.
The Wirtgen Group Performance Tracker Recycling (WPT Recycling) generates seamless documentation of every project. It records all relevant, location-specific construction site parameters and documents them in a detailed field report.
WRC 240 X and WRS 240 X
Apart from the WR series, Wirtgen also introduces the WRC 240 X rock crusher. This machine crushes coarse rocks and stones as found in hard packed stone pavement layers and stony ground, and homogeneously mixes the resulting material in a single pass. With a working width of 2,320 mm and a working depth of up to 510 mm, the WRC 240 X can achieve output rates of up to 600 t/hr.
The heavy-duty crushing and mixing rotor with HT18 toolholders and tools developed especially for the crushing process delivers ideal results in stony ground. The crushing tools have extra-large, impact-resistant carbide cutting edges and holder bases with high-tensile steel wear protection. This guarantees high utilisation rates and process reliability, even in demanding applications.
In addition to crushing rocks and stones with edge-lengths of up to 300 mm and a uniaxial compressive strength of up to 200 MPa, the machine can add and mix water and binding agents into the crushed material during the same pass, e.g. to produce base layers.
Meanwhile, the operator’s platform of the WR 240 X has been chosen for the new WRS 240 X model, and a binding agent spreading unit with a container capacity of 5.5 cu m has been integrated in the machine for dust-reduced spreading of binding agents such as lime or cement.
The WRS 240 X is suitable for deployment on motorways, industrial estates and in nature reserves with strict emission regulations. Thanks to its excellent all-terrain mobility, binding agents can be spread reliably and precisely, especially on soils with poor load-bearing properties in challenging terrain. The WRS 240 X offers the further option of pushing a binding agent silo ahead of the machine. This binding agent silo can be kept permanently filled on load bearing ground.
