The Wirtgen group presented no less than 11 models from its cold milling machine division at Bauma Munich. The ‘i’ machines also made their debut at bauma. The ‘i’ stands for intelligent emission control, an eco-friendly drive technology with which the company has converted its complete machine fleet to the new engine technology. Wirtgen has also developed numerous innovative features that further improve milling with machines ranging from the small W 35 DC all the way to the large W 250i and ensure optimum working results.
The new features include the new Rapid Slope slope sensor, which makes the Level Pro automatic levelling system developed by Wirtgen even more efficient. The Level Pro automatic leveling system is fully integrated in the machine control system and enables the milling depth to be precisely adhered to with the help of various sensors.
Practical experi¡ence has shown that especially using Wirtgen cold milling machines equipped with FCS allows rollers with different spacings to be used with a constant working width. This is why Wirtgen has developed a simplified version of its FCS system called ‘FCS Light’. This enables milling drums of the same width to be changed extremely quickly, so that a variety of different milling jobs can be carried out in quick succession.
By developing the new HT22 quick-change tool holder system, Wirtgen has succeeded in significantly increasing the maximum service life of both the upper part of the quick-change tool holder system and that of the milling drum. Generation X is the new series of point-attack cutting tools developed by Wirtgen in close cooperation with long-standing system partner Betek in Aichhalden. The result is a robust cutting tool with greatly optimised wear resistance that cuts exceptionally well at high milling output rates.
