Cold milling with large milling machines

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.

WIRTGEN cutting technology

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

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.
