The new W 100 Fi, W 120 Fi and W 130 Fi cold milling machines from specialist Wirtgen are high-performance, next generation 1m class compact milling machines. These also feature the innovative and proven technology already seen in the firm’s F-series large milling machines.

The three front loaders offer working widths of 1m, 1.2m and 1.3m with low emission engines that meet the Stage 5/ Tier 4 Final standards. All three machines are powered by state-of-the-art John Deere diesels with outputs of 265kW. Wirtgen and John Deere have tuned the torque characteristic of the engine to meet the specific needs of the cold milling process. As a result, the machines use less fuel, even when delivering high productivity and milling to a maximum depth of 330mm.

Also onboard are the digital assistance systems Mill Assist machine control, Wirtgen Performance Tracker (WPT) and the Level Pro Active levelling system. These innovative systems are said to help ensure cost-efficient and precise milling and have been proven on the firm’s large machines. Customers can now benefits from the same high-performance, efficiency and clear documentation in the compact milling class.

In automatic mode, Mill Assist selects the operating strategy with the most favourable balance between milling performance and operating costs. This increases milling performance and reduces fuel, water and pick consumption and CO2 emissions.

The milling machine operator can also preselect one of three alternative operating strategies: ECO, Performance-optimised or Milling pattern quality. For example, this will allow a user 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 allows reductions in fuel consumption and minimises pick wear. In the upper speed range, a high-quality milling pattern can be achieved, even in the case of higher area performance rates.

Wirtgen Performance Tracker automatically determines area performance rates, milling volumes and the fuel and water consumption of the machine – without the need for external surveyors on the construction site. The milling machine operator can view important performance and consumption data in the cab in real time and send an automatically generated report to the machine owner by email immediately after completion of the milling job. WPT is an optional feature that can also be retrofitted to existing compact milling machines.

Compact dimensions and optimised machine weight for easy transportation mean that the machines are more versatile and can be deployed quickly for a wide array of construction site works. The manoeuvrable cold milling machines are particularly suitable for milling work where space is limited, for example in city centres or car parks. However, high productivity means that the machines also suit surface layer rehabilitation and complete pavement removal on smaller or medium-sized construction sites. The ability to quickly change the FCS milling drums with different pick spacings and working widths means that the compact milling machines can also be rapidly reconfigured onsite to adapt to changing applications.

The new operator’s cab is said to offer high comfort and ergonomic controls and modern design. The layout offers a good view of the working areas and this is aided by the slender wasp waist of the machines as well as the installation of up to five cameras. The new control screen in the multifunctional armrest displays all machine-relevant information. Another smart solution is the access to the milling machine at the rear that automatically adjusts to the machine height. This means that machine operators have ergonomic access to the operator's cab for all jobs.
