Wirtgen has introduced its new W 150 F(i) to round out the top end of its compact milling machine class.
With a milling width of 1.8 metres, the new milling machine is ideal for use on major construction sites with restricted space such as urban environments. Its compact dimensions and optimized weight enable easy transportation allowing the milling machine to work on a multitude of construction.
As well, single-handed operation is enabled thanks to a combination of the intuitive operating concept, digital assistance systems and the Level Pro Active levelling system.
The agile front loader, with a standard working width of 1.5 metres, features the latest engine technology compliant with Stage 5 and Tier 4 Final exhaust emission standards.
The 9-litre John Deere engine delivers 422 hp and has been adapted to meet the needs of cold milling applications. The engine delivers high torque while maintaining low noise emissions under all load conditions. The compact milling machine’s fuel consumption is also significantly lower, even when delivering milling to its maximum working depth of 33 cm.
Mill Assist, Wirtgen Performance Tracker (WPT) and the levelling system Level Pro Active assist the operator while increasing milling efficiency. These systems have already delivered proof of their potential in the other F-series cold milling machines. In the case of the W 150 F(i), the largest model in the compact milling machine class, users also benefit from an automatically generated construction site report outlining clearly structured documentation of all relevant data.
In automatic mode, Mill Assist selects the operating strategy with the most favourable balance between milling performance and operating costs. This increases the milling performance while simultaneously reducing diesel fuel and water consumption, pick wear and emissions.
Mill Assist automatically controls the engine speed in accordance with the operator’s requirements and enables a broad spectrum of applications, thanks to a wide range of usable milling drum speeds.
The lower speed range enables a significant reduction of diesel fuel consumption and pick wear, while the upper speed range enables an optimum milling pattern at higher area performance rates.
The operator can also preselect one of three working strategies: 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.
Level Pro Active
The Level Pro Active levelling system is a standard feature on the W 150 F(i). Developed by Wirtgen for cold milling machines, the levelling system features an intuitive operating concept and ensures precise milling results.
The machine has an improved basic configuration for the integration of 3D and laser levelling systems and a revised multiplex system with three-fold scanning. All sensors and measurement values are displayed in an easy-to-read format on the control panel to maximize process efficiency. The system is fully integrated in the control system, and essential machine functions are directly interconnected, enabling a high level of automation.
Wirtgen cutting technology
The cold milling machine is equipped with the HT22 wear-resistant quick-change toolholder system with the field-proven top part HT22 Plus. In combination with the new Generation X² round-shank picks, this reduces toolholder wear by up to 25 per cent. Customers benefit from longer pick replacement intervals and the ability to change picks on-the construction site quickly and easily. The quick-change system for milling drums, Multiple Cutting System (MCS), enables rapid changes of the working width and ensures outstanding flexibility.
The operator’s platform includes ergonomically designed controls with high-quality haptics and maximum ease of operation. The machine’s laterally adjustable operator’s platform ensures an excellent view along the zero side. As well, the camera system, with two to a maximum of six cameras, provides an ideal overview of areas that are otherwise hard to see from the operator’s platform. The 127 mm control screen in the multi-functional armrest displays all machine-relevant information.
The optionally available enclosed cab minimizes the negative effects of site-related issues such as noise and dust on the operator and provides a comfortable working environment.
