The "cold excavation tool" excavates the future. The cantilever roadheader of CRRC Heavy Industry "excavates" something different!

The cantilever tunnel boring machine is a comprehensive tunneling equipment integrating cutting, loading, transportation and walking. It features low vibration and low noise and can effectively replace the drilling and blasting method in restricted blasting areas. According to different rock-breaking capabilities, CRRC Heavy Industry has developed a series of horizontal and vertical axis cantilever tunnel boring machines to meet the needs of coal mine, water conservancy, tunnel and subway construction. The equipment features unique advantages such as safety, efficiency, environmental friendliness and flexibility, and has been widely applied in urban construction.

Compared with traditional cantilever tunnel boring machines, the equipment of CRRC Heavy Industry has significant advantages. Firstly, the cutting head of the cantilever roadheader of CRRC Heavy Industry has an independent advancing function. That is, when the equipment body remains stationary, the cutting head can advance along the equipment axis for rock breaking construction. The cutting is stable, the advancing force is large, and it is more precise and efficient in contour shaping, avoiding the problems of base plate damage and "equipment breakdown" caused by frequent machine relocation during traditional equipment construction. Secondly, by integrating the strong rock-breaking capacity of the transverse axis cutting head and the flexible construction of the longitudinal axis cutting head, a rapid interchangeability technology for the longitudinal and transverse axis cutting heads has been pioneered, achieving dual functionality with one machine and enhancing construction adaptability. Meanwhile, the cantilever roadheader of CRRC Heavy Industry can be equipped with auxiliary supporting systems that facilitate construction, such as power vehicles, transformers, cable drums, water pipe drums, dust removal systems, and secondary belt conveyors, providing a one-stop overall solution for excavation, muck loading, transportation, and dust removal for construction.

As a powerful tool for non-drilling and blasting excavation, the cantilever roadheader can be widely applied in various construction scenarios such as urban subways, high-speed railways, expressways, water conservancy projects, mines, and tunnels, in response to complex geological conditions. CRRC Heavy Industry will adhere to the concept of "method first, intelligence leading", constantly innovate equipment technology levels, and provide customers with an overall solution for tunneling construction.
