Wirtgen’s latest-generation 1 m class compact milling line-up comes to market in three derivatives and features cutting-edge technologies common to the OEM’s large milling models.

Designed to perform in urban environments and restricted spaces, Wirtgen’s W 100 Fi, W 120 Fi and W 130 Fi have working widths of 1 m, 1.2 m and 1.3 m, respectively, with a maximum milling depth of 330 mm. All three machines are powered by a John Deere diesel engine meeting EU Stage 5/US Tier 4 exhaust gas emission standards.

Operating features to note include the Level Pro Active levelling system and Mill Assist machine control. Fully integrated into the machine control system, Level Pro Active enables a high degree of automation because important machine functions are directly linked to each other, guaranteeing precise milling results.

More efficient milling

In automatic mode, Mill Assist selects the operating strategy with the most favourable balance between milling performance and operating costs. The milling machine operator can also pre-select one of three alternative operating strategies, namely ‘ECO’, ‘Performance-optimised’ or ‘Milling pattern quality’. This makes it possible, for example, to predefine the required milling pattern quality on a scale from 1 (coarse) to 10 (very fine) at the press of a button.

Mill Assist also automatically controls the drive system. In conjunction with the diesel engine, a broad spectrum of applications can be realised by reducing or increasing the milling drum speed. The low-speed range enables significant reductions in fuel consumption and minimises pick wear, while in the upper speed range, a high-quality milling pattern can be achieved, even in the case of higher area performance rates.

Wirtgen’s 1 m class compact milling machines are ideal for surface layer rehabilitation and complete pavement removal on smaller or medium-sized construction sites
