In Austria, a Wirtgen W 100 CFi compact milling machine with deep milling unit is being used for trenching prior to the laying of broadband cables – just before it sets to work milling off entire pavements.
Rapid change between trenching and repair
“We have 15 Wirtgen cold milling machines in operation. In the course of our long-standing collaboration, we have come to understand the solutions and expertise of the company, and this prompted us to turn to the Wirtgen Group in Austria in this case, too,” explains Manfred Grössing, Managing Director of Hemmelmair. Once the requirements had been discussed with Wirtgen's product management team, the design department at the brand headquarters in Germany was given the development order. “We wanted our customer to be able to use the milling machine flexibly, i.e. be able to switch back to conventional repair jobs as quickly as possible,” says Manfred Stiegler, Customer Service Manager at the Wirtgen Group's sales and service company in Austria.
Solution for trenching: new cutting wheel from Wirtgen
The deep milling unit is controlled from the traditional control panel of the W 100 CFi. “This means that the machine operator can operate his milling machine in the usual way,“ explains Andreas Salz, responsible for design and development of cutting technology.
Flexible in standard and special applications
Flexible Cutter System: Maximum range of use
The Wirtgen Flexible Cutter System, or FCS for short, delivers the optimum solution for high machine capacity utilization: milling drums with a variety of tool spacings or working widths can be replaced in a short space of time. It takes only 0.5 to 1.5 hours to replace the drum, depending on the machine – converting the cold milling machine from a standard to a fine milling machine, for instance. Removing ruts from a country road, preparing a carriageway for a thin overlay using a fine milling drum or removing coatings on asphalt or concrete surfaces with a micro fine milling drum – all of these tasks can be handled with one and the same cold milling machine. The range of FCS milling drums is large, opening up a vast array of applications for cold milling machines.
