Milling action-oriented: Wirtgen P series intelligent speed Control, steadily winning tough battles

When carrying out construction on busy urban main roads and municipal roads, the construction window period is short, and the equipment is confronted with problems such as the need to adapt to different pavement materials and frequent relocation. In the construction and maintenance of new roads, each construction link such as milling, paving and compaction is closely linked. The Wittgen milling machine has a series of features such as high reliability, high performance and high output, which can complete the construction progress with quality and quantity guaranteed, and buy time for the paver to smoothly complete the subsequent asphalt paving task.

Good equipment is like a person. To achieve goals that others cannot reach, it must not only be capable of shouldering heavy responsibilities but also walk steadily and with endurance. As a new generation of large milling machines newly launched by Wirtgen China for the Asian market, the W 195P/W 205P features these characteristics. The powerful engine power control system and the MILL ASSIST intelligent milling system endow the W 195P/W 205P with strong physical strength and intelligent brain.

In addition, it is equipped with the ISC intelligent walking control system. Through the speed sensors on the four tracks and the displacement sensors on the intelligent steering cylinder, it can sense the walking status and steering Angle of the four tracks in real time and automatically adjust the speed of the four tracks.

Even under harsh working conditions, it can run steadily (reducing track slippage) and powerfully (100% effective utilization of traction force), improving driving efficiency while reducing the wear of track plates, further enhancing construction efficiency and milling output.

Practical case studies

Location: Major overhaul of National Road G213 in Kunming, Yunnan

Equipment used: W 195 P

Construction application: Large-thickness water-stabilized milling

Milling depth: 25 cm

Milling speed: 3-4 m/min

Highlight: In the major repair project of the national highway in Yunnan, Wirtgen W 195 P performed outstandingly. The asphalt layer on the road surface has been completely removed, and it is necessary to mill water-stabilized materials with greater hardness. The P series machines have taken on the role of tackling the tough problem.

The operator activates the Power high-performance mode of the MILL ASSIST intelligent milling system and sets the milling depth to 25 cm. Even at such a large working depth, the W 195P remains highly capable, with a milling speed still reaching 3-4 m/min, and the milled road surface is smooth and uniform.

In addition to the greater torque that makes the W 195 P work more vigorously, the ISC intelligent walking system it is equipped with will actively intervene in the distribution ratio of traction force among different tracks when the equipment encounters hard materials and senses the change in track speed due to the change in resistance, thereby effectively reducing the slippage of the track plates caused by the increase in resistance Moreover, it has a powerful walking drive, high milling efficiency, effectively reduces the wear of the tracks, and further saves fuel consumption.

In addition, the powerful engine of the new P series, combined with higher torque, makes the machine's application range wider and its power more powerful. Compared with the previous generation of models, the significant increase in the output of the P series has not led to an increase in total fuel consumption. It is equivalent to consuming less fuel per cubic meter of milling and generating less carbon dioxide emissions, thus achieving a more outstanding energy consumption performance.
