Comprehensive Cold Milling Product Line
Wittgen(WIRTGEN)This will bring a powerful half-meter cold Milling Machine.，Used for post-discharge construction。The outstanding advantages of this model are mainly reflected in two points.：Simple control concept and many automation functions。And another working width of 1.3 mFront discharge cold Milling Machine，This is for the North American market. F Series medium Milling Machine equipped with John Deere Engine，Designed to meet the specific needs of cold milling operations。
The exhibition of the other two large milling machines makes the product range of cold milling machines for the European and American markets more comprehensive.。W 210 FiAnd that application range is wide，It includes a series of construction from pavement repair to full milling and then to fine milling.。W 250 Fi This large milling machine is powerful.，The company focuses its research and development mainly on material loading capacity and machine performance.，Designed to maximize production for the customer。
F Series Cold Planers can also be equipped with innovative Mill Assist Machine control system and method for digital recording of construction sitWirtgenMilling output tracking and recording system。
Cold regeneration and soil stabilization proces - Consistent with sustainable development，And is economical and efficient
W 380 CRi ,WR 200 XLi And WR 250i Resources can be fully and efficiently utilized，This occupies a certain prominent advantage in the market.。W 380 CRi Post-discharge mode can be adopted for cold recycling construction，Mixing performance up to 800 t/h，Used for large-width pavement repair operation。
CR The series of Recycling Machines can be used for cold recycling construction in situ（CIR），But also can carry out full-depth cold regeneration construction.（FDR）Project。In addition to cold recycling construction，WR Series Wheeled Reclaimer is also suitable for soil stabilization。Working width 2.4 m，And has strong milling and mixing performance.，Overall optimization of configuration，It can fully meet the needs of large area operation.。
With digital solutions from Wirtgen，AutoTracAutomatic steering assist system and WPT（WirtgenPerformance Yield Tracker System），The construction efficiency has been greatly improved.。
Flexibility is key，Fully meet the application of front paving and side paving slipform paving
Wittgen(WIRTGEN)Will carry SP 15i And SP 94i These two customized concrete slipform Pavers are unveiled.。SP 15i Highly flexible，Pecially when a concrete monolith is laid on its sides，Paving molds of various shapes can be flexibly installed on the left or right side of the complete machine.。
The bridge of the aircraft can also be operated telescopically.，Therefore, the operator can have a wide and clear view of the working area.，Thereby ensuring a high-quality paving effect.。In addition，This exhibition model is also equipped with Wittgen's professional research and development. AutoPilot 2.0 Automatic navigation system for slip-form pave，Can realize non-datum line slipform paving。
SP 94i It is a fully modular positive paving slipform Paver.，Equipped TeleMold The four-track Paver of the system also made a brilliant appearance in Las Vegas.，This paver is fast.、Flexibility to change working width，It should be noted that，Replacement working width up to 3 feet per side，Six feet in all。
Innovative Cold Milling Technology
Using the Milling Assist System，The working efficiency of the milling operation can be greatly improved。In automatic mode，The system adjusts intelligently based on milling performance and construction cost，Select the appropriate mode of operation，As a result, the engine speed and the drum speed are automatically adjusted accordingly。
In low gear range，It can greatly reduce the fuel consumption and wear of the cutter head.；In the high range，Even in the face of large area milling operation，An ideal milling texture can also be obtained.。The operator can select three operation modes.：“ECO Energy saving mode”，“Performance optimization” And “Milling texture quality”
Using the Wirtgen milling production tracking system（WPT）It can accurately calculate the milling area of the machine.、Milling output and energy consumption data。The laser scanner is used to measure the cross section of the road surface that needs to be milled。And then with the help of GPS Positioning system and other sensors accurately measure milling area and milling volume。The operator can continuously track and obtain important information in real time through the display screen of the control panel。After completion of milling construction，All data related to production and energy consumption will be generated automatically，And send it to the operator's mailbox.。This greatly reduces construction time and construction costs.。
Cold Milling Specialist from Wittgen USA Tom Chastain Las Vegas Convention Center West 208 on March 16, 2023 - Held in Hall 210 Conexpo In the educational lecture, the application of cold milling construction and advanced cold milling technology are introduced in depth.。
Reclamation and soil stabilization construction using resource-saving technologies
Wittgen WR Series of Recycling Machines equipped with satellite-based positioning and navigation AutoTrac Automatic steering assist system，This not only makes the construction more accurate and efficient,，It also greatly reduces the workload of the operator.。
It can be within the tolerance of centimeter level.，The specified overlap spacing between rows according to the preset reference road surface and the adjacent road surfaces，Precise control of steering，This allows the machine to continue working at the desired working width，Significantly improve work efficiency，Achieve double harvest of benefit and environmental protection。
WR Series machines can also be equipped with the Wirtgen Performance Yield Tracker system，The system will collect all relevant important construction parameters.，Provide a comprehensive database for job site analysis and documentation。For example：During construction of soil stabilization，Working width、Depth of work、Construction area、Fuel consumption and other parameters are all recorded.，The operator can obtain relevant information at any time.。
Non-baseline slipform paving improves construction efficiency and safety
Compared with the traditional measurement method,，Wittgen's professional research and development AutoPilot 2.Automatic Navigation System for Slipform Paving，So that that slipform pave without a reference line is realized。
The system provides precise control of the machine's height adjustment and steering，Suitable for all side pavers and side Spreaders。It can also refer to GNSS Signals and various onboard sensors（Depending on the configuration，Uch as airborne ultrasonic sensors,）Data provided，Non-datum line slipform paving is adopted.，The construction party does not need to carry out the time-consuming installation and removal of the baseline.。
Even for small radii and complex terrain，It can also be fast、Accurately complete the paving operation。Wittgen AutoPilot 2.0 Slipform Paving Autopilot for machine control and remote control from a single source。
