The SRZY200E Two-Arm Tunnelling and Rock Drilling Rig is a brand-new, intelligent, high-end rock drilling equipment independently developed and manufactured by our company. Specifically designed for construction projects such as highway tunnels, main tunnels for high-speed railways, inclined shafts, cross-cuts, and pilot drifts, this product effectively addresses the traditional drill 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 downward, extending far forward, and covering wide lateral areas—making it suitable for various bench configurations, including micro-benching, two-bench systems, three-bench systems (including the core-soil method), and inverted arches. It’s ideal for advancing excavation operations. For full-face tunnel construction, using two rigs simultaneously delivers outstanding results. Equipped with dual rotating reducer booms, the rig ensures superior control and enhanced efficiency during anchor bolt installation. Additionally, the electrical system features imported-brand components and an IP67-rated controller that provides precise output control while offering advanced protection mechanisms such as overcurrent, overload, phase failure, and overheating safeguards—all contributing to improved energy efficiency and heightened operational safety.

　　It employs hydraulic cylinders from world-class manufacturers, ensuring reliable performance and superior functionality of the hydraulic system. Equipped with a four-wheel-drive engineering vehicle chassis, it guarantees excellent tire contact even on rugged terrain, offering outstanding road adaptability, rapid relocation capabilities, and exceptional climbing ability. The machine features a two-speed forward and two-speed reverse hydrostatic transmission system, renowned for its high reliability and ease of operation—perfect for swift movement across flat surfaces—and allows for quick, automatic switching between two distinct operating modes: one optimized for high torque during uphill climbs, while the other ensures efficient, high-speed travel on level ground. Additionally, it is fitted with a 18kW WORTHED-brand hydraulic rock drill boasting world-class power output, complemented by a dual-buffer system that reduces consumable wear by up to 30% compared to single-buffer systems. Its high-frequency, high-pressure impact design delivers unmatched explosive force, making it particularly well-suited for working in hard-rock environments such as mines and quarries. This results in exceptional operational efficiency, delivering powerful drilling performance with significant rotational torque, enabling rapid hole penetration and boosting overall construction productivity. Finally, the machine incorporates imported alloy materials throughout its moving components, ensuring superior lubrication levels, ample mist-lubrication coverage, and an advanced oil-air interface system at both end faces.

　　The entire vehicle drilling operation is conducted entirely via remote control, allowing real-time monitoring of construction conditions, ensuring precise positioning, smooth movements, and high feasibility.
