1. Full Operational Capability: The system is equipped to perform arch support installation for all three tunnel excavation methods—full-face, two-stage, and three-stage techniques—thanks to its unique fold-and-telescoping boom structure, which allows the arch-support unit to extend deep into the three-stage section for efficient installation. 2. High Efficiency: The equipment can transport multiple arch frames directly into the tunnel on-site and install them in a single operation. During three-stage construction, the main boom handles tasks at the top level, while the two auxiliary booms simultaneously assemble the arch frames for the middle stage. As a result, installing two arch frames—one for the three-stage section and another for the middle stage—can be completed in as little as 1 hour, significantly outperforming both manual labor and current market-leading arch-support machines. 3. Cost-Effectiveness: Operating this advanced equipment requires only 2 to 3 workers to complete the entire arch-support process, drastically reducing labor costs compared to traditional manual methods. This not only enables fully mechanized construction operations but also allows the equipment to efficiently serve two working faces simultaneously, delivering substantial economic benefits and social value to construction companies.

蒙自A9 manipulator wet spray trolley (plateau version)

Wet spraying machine is widely used in hydropower tunnel, underground plant, subway engineering, railway tunnel, military underground engineering and highway engineering and other construction fields. Compared with dry spraying, wet spraying technology has the advantages of high production efficiency, low resilience and guaranteed engineering quality, creating a new model of green environmental protection construction.
