On May 15, 2025, in Changsha, Hunan Province - with the theme of "High-end, Intelligent and Green", the 4th Changsha International Construction Machinery Exhibition (CICEE 2025) grandly opened at the Changsha International Convention and Exhibition Center. As a leading enterprise in China's construction machinery industry, Liugong participated in the exhibition with a strong "all-scenario intelligent equipment matrix", showcasing nearly 20 breakthrough products, among which the unmanned road roller became the focus of the entire event.

Technological Breakthrough: Creating a new benchmark for intelligent compaction

The unmanned roller of Liugong is equipped with a self-developed centimeter-level path tracking algorithm, supports multi-machine collaborative operation, and enables real-time monitoring of compaction quality through the cloud. It has been widely applied in many major projects such as the Baotou-Yinchuan High-Speed Railway and the Lawa Hydropower Station.

Practical test: Conquer the Extreme engineering challenges

Baotou-yinchuan High-Speed Railway: Smart Construction Empowered by Technology

At the construction site of the Baotou-Yinzhou High-Speed Railway in Bayannur City, Inner Mongolia, the unmanned roller of Liugong integrates multiple advanced technologies. Through cloud-based intelligent planning, this equipment can precisely determine the compaction length, number of passes and overlap width, ensuring that the pavement compaction effect meets the design requirements.

Project leader Mr. Zhou stated, "The unmanned road roller from Liugong effectively avoids the potential risks caused by human operational errors, enhances the compaction effect, and reduces the labor intensity of construction workers."

Lawa Hydropower Station: A divine weapon on the Plateau

At the Lawa Hydropower Station located at an altitude of 2,650 meters, the unmanned large-tonnage single-drum roller from Liugong has performed outstandingly in the face of challenges such as oxygen deficiency at high altitudes, hard granite rockfill and tight construction schedules. This device features outstanding high-altitude adaptability and a compaction depth of over 1 meter, enabling it to maintain stable performance during high-intensity operations lasting more than 20 hours a day. This marks a breakthrough for Liugong in achieving autonomous operation in high-altitude environments.

Gansu Qingfu Highway: Ushering in a New Era of Driverless Technology

In the first phase of the S28 Lintai to Huating Expressway in Gansu Province, the world's first application case of water-stabilized standard construction technology drone swarm operation was realized. These devices are equipped with the Beidou positioning system, which collects environmental information through sensor devices and uploads it to the base station. Based on the parameters, the optimal operation path, speed and number of compaction times are planned. Only one person is needed to control the three devices, which significantly improves the construction efficiency and quality and reduces the labor cost.

Intelligent Manufacturing for the Future: Ushering in the Unmanned Era of Construction Machinery

From expressways to highland canyons, from single-machine intelligence to cluster operations, Liugong Road Machinery, with technological innovation as its pen, is writing a new chapter in the intelligentization of China's construction machinery. On the stage of CICEE 2025, what is witnessed is not only the debut of unmanned equipment from Liugong Road Machinery, but also the resounding steps of the construction machinery industry towards the future.
