Introduced at Bauma 2022, the the W 100 Fi, W 120 Fi and W 130 Fi compact milling machines from Wirtgen find influences from the state-of-the-art technologies in the company’s F-series of large milling machines. The line of compact class machines can also be fitted with a comfort cabin, a first, says the company, which adds that the cabins increase the safety of machine operators and the comfort of their workplace.
The front loaders with working widths of 1 m, 1.2 m and 1.3 m, feature engine technology compliant with EU Stage 5 and U.S. Tier 4 Final exhaust emission standards. Their diesel engines delivers a rated output of 355 hp (265 kW) and are tuned to meet the specific needs of the cold milling process, delivering sufficient torque at engine speeds as low as 1,200 rpm and achieving maximum torque at 1,500 rpm. Working speeds range from 1,200 to 2,100 rpm.
Capable of milling to a maximum depth of 330 mm, the machines feature Mill Assist, Wirtgen Performance Tracker (WPT) and Level Pro Active digital assistance systems.
In automatic mode, Mill Assist selects the operating strategy with the most favourable balance between milling performance and operating costs with the aim to increase milling performance while simultaneously reducing diesel fuel, water and pick consumption.
The Level Pro Active levelling system, developed by Wirtgen for cold milling machines, features informative operating panels and is intuitive and easy to use. All connected sensors and measured values are clearly 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 designed to make the operator’s job easier, such as automatic lifting for driving over manhole covers.
The newly developed operator’s cabin is characterized by ergonomically designed control elements with high-quality haptics and maximum ease of operation. In addition to the slender wasp waist of the machine, up to five on-board cameras provide a view of all important working areas.
A five-inch 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.
