Wirtgen F-Series Compact Milling Machines for Cost-Efficient and Sustainable Cold Milling
Back in 2022, WIRTGEN celebrated the market launch of its completely redesigned generation of compact milling machines. Industry-leading state-of-the-art technologies from the proven F-series large milling machines have now been integrated in the W 100 Fi, W 120 Fi and W 130 Fi compact milling machines. For the first time, compact class machines can be fitted with a comfort cabin. This not only increases the safety of machine operators, but also the comfort of their workplace. The machines, with working widths of 1.0 m, 1.2 m and 1.3 m, feature the latest and currently most environmentally friendly engine technology compliant with EU Stage 5 / US Tier 4 final exhaust emission standards. The state-of-the-art diesel engine delivers a rated output of 265 kW (355 hp). Wirtgen and John Deere have precisely tuned the torque characteristic of the engine to meet the specific needs of the cold milling process. The engine already delivers sufficient torque at engine speeds as low as 1,200 rpm, achieves maximum torque at 1,500 rpm and offers a very wide working speed range of 1,200 to 2,100 rpm. As a result, the machines use significantly less fuel, even when delivering the highest productivity and milling at the maximum depth of 330 mm. Also onboard are the digital assistance systems Mill Assist, Wirtgen Performance Tracker (WPT) and the Level Pro Active levelling system. These systems have already delivered clear proof of their potential in the F-series large milling machines. Now, customers can look forward to the benefits of high milling performance, maximum efficiency, and clear documentation in the compact milling machine class. Mill Assist automatically controls the engine speed and simultaneously provides a wide range of usable milling drum speeds for an enormous spectrum of applications. The low speed range enables significant reductions in fuel consumption and minimizes pick wear. The upper speed range enables the achievement of an optimal milling pattern, even in the case of higher area performance rates. The operator can additionally pre-select one of 3 operating strategies for each milling job: “ECO”, “performance-optimized” or “milling pattern quality”. This makes it possible, for example, to pre-define the required milling pattern quality incrementally from coarse to very fine at the press of a button. Compact dimensions and optimized machine weight for easy transportation make these machines perfect for a multitude of different construction site scenarios. Whether on motorways, main roads, car parks or inner-city projects – these high-performance machines are ideal for a broad spectrum of applications. Due to their outstanding productivity, they are ideal for surface layer rehabilitation and complete pavement removal on construction sites of all sizes. Thanks to the ability to quickly change the FCS milling drums with different pick spacings and working widths, the compact milling machines from Wirtgen can also be rapidly reconfigured on-site to adapt to changing applications. Already proven in the F-Series large milling machines, the LEVEL PRO ACTIVE levelling system has now been made available for the compact class milling machines. Developed especially for cold milling machines, the levelling system features informative operating panels and is intuitive and easy to use. All connected sensors and measured values are clearly displayed on the operating panel in order to make the work processes as efficient as possible. The system is fully integrated in the control system of the cold milling machine and, as essential machine functions are directly interconnected, provides a high level of automation. The system also offers many automatic and additional functions that make the operator’s job easier, for instance, automatic lifting for driving over manhole covers. The redesigned operator’s cabin is characterized by ergonomic control elements with high-quality haptics and maximum ease of operation. In addition to the slender wasp waist of the machine, up to 5 on-board cameras provide an ideal view of all important working areas. The new 5’’ control screen in the multifunctional armrest displays all machine-relevant information. The access ladder to the cabin at the rear of the machine is fitted with an automatic height adjustment system. This assures that the machine operator can easily and safely access the platform in all working scenarios.

In automatic mode, Mill Assist selects the operating strategy with the most favorable balance between milling performance and operating costs. This increases milling performance while simultaneously reducing not only diesel fuel, water, and pick consumption, but also CO2 emissions.
