SRZY200E Curved-Arm Rock Drilling Rig

The SRZY200E Two-Arm Tunnelling and Rock Drilling Rig is a brand-new, intelligent, high-end rock-drilling device independently developed and manufactured by our company. Specifically designed for construction projects such as highway tunnels, main sections of high-speed railways, inclined shafts, cross passages, and pilot drifts, this product effectively addresses the traditional drilling rig's limited adaptability to varying tunnel cross-sections, enabling it to achieve "multi-purpose functionality" in a single machine. Capable of handling all types of working conditions, the rig excels at drilling high up, reaching deep below, extending far forward, and covering wide lateral areas—making it ideal for various bench configurations, including micro-benches, two-bench systems, three-bench systems (including the core-soil method), and even inverted arches. For full-face tunneling operations, using two rigs simultaneously delivers outstanding results. Equipped with dual rotating reducer arms, the rig ensures superior control and enhanced efficiency during anchor bolt installation. Additionally, the rig features an advanced electrical system powered by imported brand components, complete with an IP67-rated controller that provides precise output management. This system incorporates comprehensive protective features—such as overcurrent, overload, phase-loss, and overheating safeguards—enhancing energy efficiency and significantly improving operational safety.

SRG312A Arch Support Cart

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.
