Engine Technology from John Deere
The agile front loader with a standard working width of 1.50 m (5 ft.) features eco-friendly engine technology compliant with EU Stage 5/U.S. Tier 4 Final exhaust emission standards. The 9-liter John Deere engine offers a maximum rated output of 315 kW and has been specially adapted to meet the needs of cold milling applications. It offers high torque and simultaneously low noise emissions under various load conditions. Milling is possible to a maximum working depth of 330 mm.
Digital Assistance and Leveling Systems
Mill Assist, Wirtgen Performance Tracker (WPT) and LEVEL PRO ACTIVE assist operating personnel on the jobsite. These systems are also present in F-series cold milling machines. In the case of the W 150 F(i), the largest milling machine in the compact class, users can leverage milling performance and clearly structured documentation of all site-relevant data via an automatically-generated construction site report.
In automatic mode, Mill Assist selects the operating strategy with balance between milling performance and operating costs. This increases the milling performance while simultaneously reducing diesel fuel and water consumption, pick wear and CO2 emissions. Mill Assist controls engine speed automatically according to the needs of the operator. The wide range of possible engine speeds means that the machine’s uses are broad. The lower speed range enables a reduction of diesel fuel consumption and pick wear. In the upper speed range, an optimum milling pattern can be achieved even at high area performance rates.
The operator can also select one of three performance strategies. These are: ‘ECO’, ‘performance-optimized’ and ‘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 leveling system is installed as a standard feature of the W 150 F(i). Developed by Wirtgen especially for cold milling machines, the leveling system features an intuitive operating design. The machine has a basic configuration for the integration of 3D and laser leveling systems and a revised Multiplex system with three-fold scanning. All sensors and measurement values are displayed on the control panel. The system is fully integrated in the control system of the cold milling machine. Important machine functions are directly interconnected, allowing for automation.
The operator’s platform is characterized by control elements with haptics. The machine’s laterally-adjustable operator's platform provides views along the zero-clearance side. A camera/monitor system with two to six cameras enables an overview of areas that are otherwise hard to see from the operator’s platform. The 5-in. control screen in the multifunctional armrest displays machine-relevant information. The optional enclosed cabin minimizes the negative effects of noise, dust and other site-related irritants on the operator.
The W 150 F(i) is equipped with the wear-resistant quick-change HT22 toolholder system with the HT22 PLUS. In combination with the new Generation X² round-shank picks, this reduces toolholder wear. The component promotes long pick replacement intervals and provides the ability to change picks on-the construction site. The quick-change system for milling drums, MCS (Multiple Cutting System), enables adjustment of working width.
