en.Wedoany.com Reported - Germany's Wirtgen company has launched the P-series ULTRA milling machine. Compared to classic models, this machine delivers improved efficiency in conventional milling applications. Under standard 8 cm milling depth conditions, efficiency is increased by 35%. When dealing with full-depth asphalt layers, performance is boosted by 50%.

During a three-day test, the total fuel consumption of the P-series ULTRA and its predecessor models was similar, both around 560 liters. However, due to the efficiency gains, the converted unit fuel consumption is reduced by 30%. The machine is equipped with the Mill Assist intelligent system, which monitors road surface hardness, milling depth, and tool load in real time. By simply pressing a button to select from three modes—"Economy," "Performance," and "Texture"—the system automatically adjusts engine speed, travel speed, and drum lifting.

On the same road sections and under identical asphalt conditions, the per-unit-volume cutter tool wear of the P-series ULTRA is reduced by 50%. On-site operators remarked: "In the past, after finishing one stretch, a whole set of cutters needed replacing; now, only half a set is needed. Where cutters were once changed every three days, now maintenance is only required every six days." This result stems from the synergy of software and hardware: the Mill Assist intelligent system reduces unnecessary tool wear, while the optimized high-efficiency milling drum lowers cutting resistance. It is reported that for every 4-hour operation processing approximately 600 cubic meters, cost savings can exceed 5,000 yuan.
