Global market leader Wirtgen expands product portfolio and presents innovative features.

The Wirtgen Group presented no less than eleven models from its cold milling machine division at Bauma Munich - a representative cross-section of its complete product range of small to large milling machines. 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.

In addition to the eco-compatible operation made possible by 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.

Rapid Slope

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 levelling 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. One outstanding feature is the intuitive and application-oriented operation with clear graphic displays and function keys. The sensor boasts extremely fast and highly accurate recording of measurements. At the same time, these measured values are processed in complex computations and forwarded to the machine control system. In combination with the newly developed telescoping levelling beam for scanning reference points up to 3.5 m to the side of the machine, Rapid Slope itself guarantees optimum milling results even when faced with the most complex levelling tasks.

Flexible solutions

The 'Flexible Cutter System' or simply FCS enables milling drums to be changed quickly and easily. Wirtgen has continuously optimised the system over the past 15 years. Swift conversions mean that companies can use one machine for various types of work. The range of FCS milling drums with different working widths and spacings is vast. Depending on machine, no more than 0.5 to 1.5 hours are needed to change the milling drum, quickly converting the cold milling machine from a standard milling machine to a fine milling machine, for instance.

Quick-change tool holder system

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. The overall robust system also means that the service intervals for checking the bolt pre-tension have increased from 250 hours to 500 hours. The reliable and simple bolt connection has already passed muster in the two-year-plus prototype phase of the new HT22 quick-change tool holder system.

Generation X

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 (Germany). The result is a robust cutting tool with greatly optimised wear resistance that cuts exceptionally well at high milling output rates. For instance, the new point-attack cutting tools can be used for as much as 20 per cent longer under consistently high milling output rates than conventional point-attack cutting tools on account of the innovative geometry of their carbide tips. The optimised guidance of the point-attack cutting tools in the tool holder system also reduces longitudinal wear on the tool holder. Like the HT22 quick-change tool holder system, the Generation X series of point-attack cutting tools also debuted at bauma and will be available from mid-2013.

Innovative customer solutions

With the expansion of its cold milling machine programme and new technical developments, Wirtgen provides innovative solutions that offer customers around the world substantial added value for their day-to-day job site operations.
