Arch Installation Robot KGM95300: Assisting Single Tunnels for Hydropower, Mining, and High-speed rail:)
January 15, 2026
Keda Intelligent focuses on the core pain points of hydropower underground space construction, and independently develops the arch installation trolley KGM95300. This device is specially designed for small cross-section tunnels, with a minimum adaptation of 5 meters by 5 meters for tunnel section. It can achieve the installation of 1-4 arches at once, accurately solving the industry problem of limited adaptation of conventional arch installation robot due to narrow tunnel space in projects such as pumped storage and high-speed rail one-way tunnels.
Compared with traditional manual arch erection and conventional arch installation robot, KGM95300, with the advantage of mechanized operation, significantly reduces the frequency of personnel directly participating in high-risk operations, significantly improves the safety and controllability of tunnel arch erection operations, and comprehensively guarantees the safety of construction personnel and the quality of the project; At the same time, it has the characteristics of agile operation and convenient mobility, which can greatly shorten the arch erection operation cycle, optimize the construction process, significantly improve the overall construction efficiency, completely break through the bottleneck of narrow space arch erection operation, and provide strong support for the efficient promotion of underground engineering.
Excellent energy comes from refined structural design. The KGM95300 main arm is equipped with a clamping and lifting mechanism, with a rated load capacity of 3 tons. Continuing the core advantages of the Keda arch installation trolley series, it can achieve direct support of the arch to the palm face and accurately lift the arch unit A to the arch crown. This not only improves the efficiency of construction connection, but also builds a safety protection barrier for the palm face, effectively preventing risks such as falling rocks. The left and right auxiliary arms are synchronously equipped with a towing clamping mechanism, with a rated load-bearing capacity of 1.5 tons; The towing mechanism adopts a flexible design, which can flexibly adapt to narrow tunnel spaces, allowing for unrestricted placement of unit arches; The clamping mechanism can firmly lock the arch frame, effectively avoiding offset and shaking problems. The dual protection of dragging and clamping further enhances the convenience and stability of operation.
The KGM95300 arch installation robot is another innovative achievement of Keda Intelligent Equipment in the field of underground water and electricity space operations. It not only provides efficient and safe technical solutions for the construction of hydropower underground projects, but also demonstrates the company's firm determination to practice the direction of mechanization, intelligence, and unmanned development. Assist in promoting the improvement and efficiency of underground space operations in the hydropower industry, and contribute Keda's strength to building a safe, efficient, and intelligent construction ecosystem!
