The SRG312B tunnel multifunctional arch‑support installation carriage is a new type of equipment designed for installing full‑face or bench‑method arch supports, as well as anchor bolts and mesh reinforcement. Equipped with suspended work platforms, it can also serve as an aerial work platform for quality inspection, grouting, charge placement, and anchor bolt installation, offering versatile applications. Featuring a three‑arm, three‑manipulator configuration with three suspended platforms, each arm enables automated arch‑support gripping and fine adjustments at the manipulator end, facilitating efficient arch‑erection operations and truly realizing mechanized construction.

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.

The SRZY30A single-arm tunneling and rock‑drilling rig series is a brand‑new, intelligent, high‑end rock‑drilling machine independently developed and manufactured by our company. This product line is specifically designed for drilling operations in mining, highway and high‑speed railway construction, water conservancy and hydropower projects, as well as defense‑related tunneling works. Its electrical system incorporates imported components and features an IP67‑rated controller that provides comprehensive protection against overcurrent, overload, phase loss, and overheating, delivering enhanced energy efficiency and superior safety.

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.
