SRZY200A Double-Arm Rock Drilling Rig

The SRZY200A dual-arm tunneling and rock‑drilling rig is a brand‑new, intelligent, high‑end rock‑drilling machine independently developed and manufactured by our company. Specifically designed for highway, high-speed rail, and hydraulic engineering projects, it thoroughly addresses the limited cross‑section adaptability of conventional drilling rigs, achieving “multi‑purpose functionality” in a single machine. It accommodates all construction conditions, enabling high‑reach drilling above, deep drilling below, long‑range forward drilling, and wide‑span lateral drilling, while adapting to various excavation stages—micro‑steps, two‑step, three‑step, three‑step with core‑soil retention, and invert arches. For full‑section tunneling operations, using two units in tandem delivers excellent results. Its dual‑rotary reducer‑equipped boom provides superior control and enhanced performance during anchor‑bolt installation. The electrical system incorporates imported components and features an IP67‑rated controller with comprehensive protection functions—including overcurrent, overload, phase‑loss, and overheating safeguards—ensuring greater energy efficiency and enhanced safety.

Product Introduction

The SRZY200A dual-arm tunneling and rock‑drilling rig is a brand‑new, intelligent, high‑end rock‑drilling machine independently developed and manufactured by our company. Specifically designed for highway, high-speed rail, and hydraulic engineering projects, it thoroughly addresses the limited cross‑section adaptability of conventional drilling rigs, achieving “multi‑purpose functionality” in a single machine. It accommodates all construction conditions, enabling high‑reach drilling above, deep drilling below, long‑range forward drilling, and wide‑span lateral drilling, while adapting to various excavation stages—micro‑steps, two‑step, three‑step, three‑step with core‑soil retention, and invert arches. For full‑section tunneling operations, using two units in tandem delivers excellent results. Its dual‑rotary reducer‑equipped boom provides superior control and enhanced performance during anchor‑bolt installation. The electrical system incorporates imported components and features an IP67‑rated controller that ensures safe, energy‑efficient operation with built‑in protections against overcurrent, overload, phase loss, and overheating.

Equipped with hydraulic couplers from world‑class manufacturers, the system ensures reliable operation and superior performance. Featuring four‑wheel drive and an engineering‑vehicle chassis, it delivers excellent contact between the tires and uneven terrain, offering broad road‑surface adaptability, rapid relocation, and strong climbing capability. The hydrostatic travel system provides two forward and two reverse gears, boasting high reliability and ease of operation, enabling swift movement on level ground while seamlessly and automatically switching between two operating modes—high torque for uphill climbs.

Equipped with a high‑power hydraulic rock drill from a world‑renowned brand and featuring a dual‑buffer system, it reduces consumable wear by 30% compared to a single‑buffer design. Its high‑frequency, high‑pressure impact design delivers greater explosive force, making it particularly well suited for mining and quarrying applications involving hard rock. It offers high operational efficiency, powerful impact, substantial rotary torque, and rapid drilling speeds, thereby enhancing overall equipment productivity. Constructed with imported alloy materials, it boasts superior lubrication of moving parts and employs an advanced air‑oil mist lubrication system.

All drilling operations on the complete vehicle are remotely controlled, enabling real-time monitoring of construction conditions, precise positioning, smooth motion, and high feasibility.
