Dual Shift: More quality, less fuel, wear and tear
The cold milling machines drove in staggered formation to continuously “feed” a rapid succession of 45 dump trucks with milled material. The new generation of machines impressed even such experienced milling machine operators as Valentino Pivotto, who works for milling service provider Crestani, “And not just because it was the first job following training on the machine.” It was the first time in many years that the operator had driven a Wirtgen milling machine again. “The leap forward made by the W 210 Fi in terms of control, performance and productivity was therefore enormous. Not to mention the DUAL SHIFT, which makes this machine a real benchmark in its field.”
Thanks to the new two-speed powershift transmission, which is automatically controlled by Mill Assist, a much larger range of milling drum speeds is now also available. The diesel engine also features a modern engine rating with a high torque starting at 1,300 rpm. This lowers diesel consumption and noise emissions.
The intelligent control of the two-speed powershift transmission combined with the diesel engine extends the range of milling drum speeds, both upwards and downwards. This supports significant reductions in fuel consumption and cutting tool wear in the low milling drum speed range. A high-quality milling pattern can be achieved in the upper milling drum speed range, even when working with a high area output. This makes the W 210 Fi professional machine ideal for particularly demanding milling jobs.
WPT with Numerous Additional Benefits
Gabriele Martin, milling machine operator at Ecovie, explains that milling is much more efficient with the professional machine: “It is definitely different from other cold milling machines. Especially when it comes to fuel consumption, which has really been reduced without performance losses. Another interesting feature is the WPT system, which provides a wealth of data”. This is true in two aspects. The Wirtgen Performance Tracker (WPT) now makes it possible for the first time to precisely determine the milling work actually performed and “eliminate all uncertainties about the project’s parameters”.
The machine’s performance and consumption data are also extremely valuable to Martin. “I can send all this data directly from the machine, which means we immediately receive a comparison of costs and productivity. This makes job-site cost analysis much easier.” At the same time, efficiency analyses are also a valuable decision-making basis for future orders. The machine operator then knows which milling machine is the most efficient solution for the respective job.
The three milling service providers had opted to primarily use three W 210 Fi machines for the rehabilitation of the A31 motorway. “This machine allows the operator to concentrate more effectively on the work, thanks to the excellent visibility and the new control and data acquisition systems,” says Massimo Valerio, pointing out the control panel of the new large milling machines.
Thanks to the newly designed operating concept, the Girardini operator not only has a clear overview of all the most important data on the milling process and the milling machine condition on a central seven-inch control panel; the operating convenience is also enhanced by control panels for levelling or for controlling the discharge conveyor. “At the end of the day, the operator’s platform really makes all the difference,” says Valerio, who is relieved of many tasks by the new Mill Assist control system.
