Wirtgen's new W 100 F milling machine features a front loading system and a standard working width between 3 and 4 feet. The unit, the latest addition to Wirtgen's range of cold milling machines which is now comprised of 16 models, features the Flexible Cutter System (FCS) as an option.
This patented system permits a swift change of milling drums so that a single machine can perform a range of different applications. Using FCS drums, customers have working widths ranging from 1 to 3 feet at their disposal.
Level Pro for more precise milling results
Wirtgen has now developed its own system with a software specially programmed for cold milling machines.
Level Pro can be used with the new cold milling machines with a 3-foot working width for the first time. The entire system consists of sensors, a control unit and an operating panel for the driver. The most important parameters, such as the set and actual values for the milling depth on the right- and left-hand sides of the machine and the slope are clearly shown on the graphics-supporting digital display of the Level Pro operating panel.
The machine operator can enter or correct the values quickly and securely with the large-surface tactile switches. Modern digital signal processing ensures the supreme precision of the milling results on the jobsite.
The Level Pro operating interface is divided into a total of three areas with separate displays. The left- and right-hand displays are for all functions concerning the left or right milling side respectively. An additional display at the center can be used to enter further pre-settings independently of the ongoing application, for example, the calibration for switching between milling depth and slope. Shift keys can then be used to seamlessly transfer these parameters to the left or right-hand side of the machine.
The new leveling system can be operated intuitively. Level Pro has been extensively tested by customers under tough on-the-job conditions and the response has been extremely positive. The system is installed at an easy-to-reach location on the right-hand side of the operator's platform, next to the main operating console.
Engine with power boost, low consumption
The engine of the new cold milling machine is a 6-cylinder turbo diesel engine from Cummins. Thanks to the elastic mounting, the engine is much quieter.
These special engine features result in an increased productivity and improved daily performance combined with an economical mode of operation. In milling and travel drive, the engine speed is automatically controlled — an additional benefit which helps to reduce diesel consumption.
"Less is more" ergonomic design
On the operator interfaces, the functions have been optimized in such a way that the number of switches was reduced by some 20 percent.
The operator has all the most important functions directly in view on the clearly arranged main operating console. From a seated position, he or she can safely and comfortably operate all the control elements. In addition, all central control elements, such as the operation of the side plate, are also integrated in the right-hand armrest.
Fully automatic functions simplify operation
A range of automatic functions simplify the milling machine driver's everyday tasks. The automatic water system ensures that water is only selected when actual milling work is taking place, which controls water consumption. The milling drum is also switched on or off automatically.
Another example of the increased convenience of operation is the combined operation of the scraper blade and gradation control beam at the milling drum. Both components can either be fixed or set to a floating position at the push of a button.
Additionally, the conveyor speed is controlled automatically for the primary conveyors: even when the engine speed is reduced, it's ensured that the speed at which the milled material is loaded is constant.
