The other day，3 DynapacSD2550CSThe paver undertookG0611 Zhangye to Wenchuan National Highway Tongren to Saierlong（Qinggan boundary）Asphalt Paving Work in Section Project。Under harsh conditions at high altitudes，SD2550CSDemonstrate superior performance and adaptability，Help customers advance the project process。

Tongren – Saierlong Expressway，From Longwu Town, Tongren County, Qinghai Province，Connect with the section from Yashilu to Tongren in Hualong County of the built Zhangwen Expressway，It stops at Saierlong Township at the junction of Qinghai and Gansu.，It is located in Youganning Town, Henan Mongolian Autonomous County, Huangnan Xizangan Autonomous Prefecture.，The whole section is over 3600 meters above sea level.，Location“Sanjiangyuan”Protected area，The ecosystem is fragile，The topography and geology are complex，The annual precipitation is large，A variety of harsh natural conditions have created difficult construction conditions.。

SD2550CSIt is the flagship model of Dynapac high-end paver series.，It is an asphalt paving equipment with excellent performance and high reliability.，Excellent paving performance and superior stability。Its excellent performance in plateau construction in the past has especially made the old customer Qinghai Traffic Control trust.。This time, Qinghai Traffic Control once again handed over the construction task under harsh working conditions to Dynapac.，Equipped with 11.5 m wide screedSD2550CSThe paver lived up to expectations，And that field operation efficiency and the construction quality are remarkably improve.。Under severe working conditions，DynapacSD2550CSThe advantage of：

Powerful engine power：

Lack of oxygen on the plateau、In a low-temperature environment，According to statistics, every 1000 meters above sea level，Equipment efficiency will be reduced by 15 percent%Left and right。In this case，Speed drop caused by insufficient power is common in similar equipment.、Black smoke, etc.“High reverse”Symptoms，And DynapacSD2550CSThe paver is equipped with a Cummins high power engine，Ensure continuous and stable output of surging power in high altitude areas。

Combination of economy mode and automatic transmission mode，Allows the operator to steplessly adjust engine horsepower based on load condition，Ensure energy-saving and efficient operation of the machine at high altitudes。

 

Excellent screed：

Dynapac has a unique patented 4-axis support screed for superior resistance to deformation。In case of construction with large paving width，The lower support cylinder only extends half way，Form two fulcrums，To ensure the rigidity of the telescoping portion.，Provides excellent load carrying capability after the screed is fully extended，Full avoidance of deformation and distortion，So as to ensure excellent paving quality.，Ensure stability and accuracy during paving。

Efficient gas/Electric Heating System can Overcome the Influence of Temperature Difference between Plateau and Desert，O that the temperature of the screed is uniformly and rapidly increased to meet the operation requirement，The paving effect of high compactness can make the subsequent compaction work easier and faster.。

11.Application of 5 m wide screed，Can pave the whole road surface at one times，Reduce seams，And that pave efficiency is remarkably improved.，The construction period is shortened，To maintain excellent paving flatness under unstable climate conditions at high altitudes.、Compactness、Uniformity。

Excellent maneuverability for difficult terrain：

The Dynapac paver features an advanced undercarriage and a powerful power system，It can easily cope with complex terrain in high altitude areas.。

Optimized walking system design provides a smooth ride and perfect grip，Ensure stable operation at high altitudes。

Intelligent monitoring system：

The intelligent control system provides intelligent monitoring for the whole paving process.，Ensure the most accurate workflow。

Through real-time monitoring of paving quality、Engine status and other key parameters，Timely and accurate operation，Improve construction efficiency and quality。

Powerful、Intelligent border control system with simple operation，Either auger adjustment、Leveling control，Or material calculation、Camber slope adjustment，It's all simple and clear、Smooth and easy to use。

DynapacSD2550CSWith its excellent performance, the paver ensures the efficient promotion of the Tongsai high-speed project.。As a national highway network，And the expressway network in Qinghai Province.“Three vertical lines, four horizontal lines and ten connecting links”An important part of，After the completion of Tongsai Expressway, it will implement the strategy of developing the western region.，Strengthen the economic and social ties between the districts and counties in Qinghai Province and the surrounding provinces and regions.，Promote the development of tourism resources along the line，It is of great significance to improve and safeguard people's livelihood.。
