The W 120 Fi compact milling machine from Wirtgen will make its world premiere at World of Asphalt 2022.
The new machine joins the W 100 Fi, W120 FTi and the W 130 Fi in Wirtgen’s F-series line of compact milling machines.
Unique in their industry segment, the technology incorporated in the proven F-series large milling machines have now been integrated in the company’s F-Series of compact milling machines.
The W 120 Fi and the W 210 Fi large milling machine will be on display at World of Asphalt 2022. Both machines feature Mill Assist, which delivers high efficiency in the milling process.
The front loaders with working widths of 1 metre, 1.2 metre, and 1.3 metre are powered by John Deere engines that deliver a rated output of 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 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 achieve considerably better fuel consumption, emit less carbon dioxide and are much quieter – even when delivering high productivity and milling to the maximum depth of 330 mm.
Wirtgen Performance Tracker
Also onboard are the digital assistance systems Mill Assist, Wirtgen Performance Tracker (WPT) and the Level Pro Active leveling system.
In automatic mode, Mill Assist selects the operating strategy with the most favourable balance between milling performance and operating costs. To achieve the ideal balance, the system automatically adapts various parameters and provides recommendations to the operator. This not only increases milling performance, but also reduces fuel, water and pick consumption as well as carbon dioxide emissions.
Level Pro Active
Already proven in the F-series large milling machines, the Level Pro Active levelling system has now been made available for compact class milling machines. Developed by Wirtgen for cold milling machines, the levelling system features informative operating panels to improve ease of use. All connected sensors and measured values are displayed on the operating panel 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 highly maneuverable cold milling machine is particularly suitable for milling work where space is limited, for example in city centres or in parking lots. They are also ideal for surface layer rehabilitation and complete pavement removal on smaller or medium-sized construction sites.
Thanks to the ability to quickly change the FCS milling drums with different pick spacings and working widths, the compact milling machine from Wirtgen can also be rapidly reconfigured on-site to adapt to changing applications. For example, in the case of the W 120 Fi, users can choose between the standard 1.2 metre milling drum and FCS milling drums with widths of 0.6 metres and 0.9 metres.
Premium operator cab
The newly developed premium operator’s cabin of the W 120 Fi delivers comfort via ergonomically designed control elements and a modern design. The familiar overview of all relevant working areas is provided by the slender wasp waist of the machines and up to five cameras. The new 5-inch control screen in the multifunctional armrest clearly displays all machine-relevant information.
Another smart solution is the convenient access to the milling machine at the rear that automatically adjusts to the machine height. This assures that the machine operator can easily and safely access the platform in all working scenarios.
