This equipment is a fully automated multifunctional steel arch erector designed specifically for tunnel and underground construction projects. It is mainly used for transporting, positioning, lifting, and installing steel arches. The machine adopts a four-wheel drive chassis with dual driving and steering systems, offering excellent maneuverability and climbing ability, making it suitable for a wide range of complex tunnel environments.

The arch erection system features a three-section telescopic boom with three synchronized manipulators, enabling efficient multi-point arch installation. It is powered by a dual-mode system (diesel and electric), ensuring reliable long-duration operation and adaptability in areas with unstable power supply. The control system supports both wireless remote and manual operation, greatly enhancing safety and operational flexibility.

Optional modules such as hydraulic breakers, welding machines, borehole cleaning units, and grouting systems are available to further expand its capabilities and improve construction efficiency.

With its high load capacity, intelligent control system, and modular configuration, this steel arch erector is widely used in railway, highway, hydropower, and urban subway tunnel projects. It is an ideal solution for improving automation, efficiency, and safety in tunnel construction.
