W 250 Fi Large milling machine

Large milling machines are designed with a milling drum arranged in the centre of the machine and a forward-loading two-stage conveyor system. They are therefore called front loaders. The powerful, slewing and height-adjustable discharge conveyor enables large trucks to be loaded quickly and with maximum flexibility. Front loaders are usually equipped with a walk-through operator‘s platform offering a high level of operator comfort. Alternatively, they are supplied with a hydraulically moving and swivelling operator’s cabin. Numerous intelligent automated features support the operator in performing his job. Front loaders are equipped with four hydraulically steerable and height-adjustable track units.

The innovative MILL ASSIST machine control system always adjusts the most favourable relationship between performance and cost when in automatic mode. The process is optimized by automatically adjusting the speed of the diesel engine and milling drum, the traction drive, the water system and the machine’s advance rate. This relieves the machine operator of a tremendous part of his workload while at the same time improving machine performance and minimizing diesel consumption, CO2 emissions, pick consumption and noise emissions.

Results of high quality are the main goal of every construction project. This applies to road rehabilitation using cold milling machines and cold recyclers as well as to soil stabilization and the extraction of useful minerals using surface miners. Optimum interaction between the milling drum, toolholder and pick is essential for precise, efficient paving removal.

WIRTGEN is a market leader in cutting technology and offers customers perfectly matched, high-performance cutting systems. WIRTGEN is also constantly developing its cutting technology components further. Such further developments are largely based on practical experience and feedback from our customers.

WIRTGEN levelling technology controls height, depth and slope to achieve results of maximum precision. In the process, the system continuously reconciles the actual values with a preselected target value, correcting any deviations by means of proportional control. State-of-the-art machine engineering ensures levelling results of consistently high quality while at the same time relieving the machine operator of a significant part of his workload.

WIRTGEN offers customers reliable hardware and software developed in-house. Different systems are used depending on the construction project to be completed and local conditions on site.

WIRTGEN machines are fitted with a machine control system of the highest quality, in which the large proportion of software developed in-house plays the decisive role. WIRTGEN puts a special focus on continuous improvement, which has the added effect of significantly increasing the operational reliability of the machines. In addition, many years of experience in software and hardware development allow for higher and more flexible machine functionality in terms of applications and meeting specific customer requirements.
