The other day，GPavement Renovation Construction of 15 Coastal Expressway in Dafeng Section of Yancheng, Jiangsu Province Has Been Successfully Completed，At the construction site，8 DynapacCC6200 double steel wheel roller at high speed、Efficient、Consistent performance of high quality，Returned the trust of the owner, Jiangsu Expressway Engineering Maintenance Co., Ltd.，The construction task was successfully completed in a very short period of time.。

It is the star product of the high frequency resonance compaction technology originated by Dynapac.，CC6200 large double-drum roller has become the quality assurance of various high-grade pavement compaction at home and abroad since it was put into the market.。Thanks to 67HzHigh vibration frequency of, CCEach steel wheel of 6200 can hit the material 4020 times/Minute，That is to say, the vibration frequency of the whole machine can reach 8040 times/Minute，Intensive vibration leads to excellent road surface smoothness，And wave or washboard paths do not appear.。

High frequency vibration also results in faster compaction。At the same time of increasing speed，Compaction flatness tends to decrease，But DynapacCCThe high-frequency vibratory compaction technology of the series of double-drum rollers can guarantee the organic unity of high-speed operation and high quality and high flatness at the same time.，This has also become the most unique feature and advantage of Dynapac in the industry.。

Resonance technology also contributes a lot to the construction quality.，It is applied so that the steel wheel does not break the aggregate、Does not destroy the structure of asphalt layer，The adhesion performance of that road surface is greatly enhance。On the principle of physics，High frequency waves due to short propagation distances，Therefore, the impact on the construction environment is minimized.，This has also become another powerful safeguard for the whole machine to provide environmental protection.。

CCSoft start and soft stop function of 6200，Make the equipment automatically realize slow start and slow stop in the start and stop stages.，Ffectively prevent that steel wheel from rubbing oil in the compaction proces、Rubbing up bulges and other phenomena，Bring the best road surface smoothness。No longer rely on the operation experience of the operator to achieve continuous and stable construction quality，This is the ultimate effect of Dynapac Intelligent Construction Operating System.。

DynapacCCThe 6200 features a unique dual vibratory pump design，Its front and rear drum vibratory units are driven by separate pumps，Only one specified vibrator can be satisfied for each drive pump。This design can give better play to the efficiency of the equipment.，And that energy consumption is reduce to the greatest extent.，At the same time, the traditional front and back vibration switching system is cancelled.，And that reliability of the equipment is improve.。Efficient hydraulic system，Also leads to lower energy consumption：Benefit from the closed circuit specially designed in cooperation with internationally renowned suppliers of hydraulic components，Utilize a dedicated charge pump and shuttle valve，DynapacCCThe 6200 roller has effectively reduced the hydraulic system load and hydraulic oil demand.，Its hydraulic oil consumption is less than that of similar equipment.，Only 40 liters of hydraulic oil are needed for the replacement of the whole machine，The use cost can be effectively reduced.。

Dynapac Series High Performance Pavement Equipment，It is the most reliable solution to achieve the owner's high-quality construction project.，It is the best choice for various high-grade pavement projects.。Join hands with you，Build the future together！
