XCMG Unmanned Cluster Set a New Record!

Shanghai-Nanjing Expressway has normalized unmanned construction after one year of practice. In Wuxi section, XCMG unmanned cluster can complete the construction of 1.6km of surface course in one day, accelerating the project! On the site, 2 intelligent super wide pavers, together with 9 double drum rollers, are marching forward together on 19m wide pavement.

Through years of technical polishing and practicing, XCMG's unmanned intelligent equipment far exceeds the traditional ones in efficiency. As for construction quality, the mean square deviation of the evenness of the unmanned construction is only 0.45, far lower than the national requirement of 1.2. Unmanned cluster achieved the ultimate smoothness and flatness of the pavement.

Higher efficiency, better quality. The fast development of unmanned clusters is realized by continuous innovation:

The trimming accuracy is improved from 2-5cm to less than 2cm through visual sensor and real-time distance sensor. A model is established by optimizing the trajectory planning algorithm to accurately calculate the effective compaction time, so the eight rollers could advance and reverse in the echelon formation, making up the world's largest unmanned rollers cluster. By detecting the water level, the vehicle can automatically retreat to the water tanker and add water.

The project party said, ‘XCMG's unmanned cluster construction scheme is mature, advanced practical. It provides a new and reliable solution for road management and maintenance.’

From single equipment to cluster strategy, from water stable layer paving to centralized maintenance project, XCMG unmanned cluster has gained rich experience in road construction. The super smooth road is gradually coming into reality.
