Summary:
In tunneling under complex geological conditions, conventional drill-and-blast equipment often faces numerous challenges, including limited operational reach, low coordination efficiency, and significant safety risks in high‑hazard environments. How can we balance efficiency and safety when excavating large‑section tunnels, caverns, and drifts? Zhengxun Heavy Industry has offered a breakthrough solution: the ZXZY200 dual‑curved‑arm rock‑drilling rig. As a highly efficient, multi‑functional machine specifically designed for tunneling in challenging geologies, the ZXZY200 centers on a “dual‑curved‑arm hydraulic system,” redefining intelligent underground excavation.
A “subterranean dancer” as agile as an arm, doubling efficiency.
The ZXZY200 breaks the physical limitations of traditional single‑arm or straight‑arm equipment. Its bi‑curved boom features a biomimetic joint design, enabling independent multi‑directional movements such as 360° rotation, pitch, and extension/retraction. This multi‑degree‑of‑freedom motion not only expands the machine’s working envelope by more than 40% but also significantly reduces the tedious steps involved in frequently repositioning the equipment during construction. Even more remarkable is its “dual‑arm collaborative control” technology: thanks to a hydraulic synchronization system, the two arms can drill simultaneously or alternate operations, cutting single‑cycle cycle times by 30% and truly delivering tunneling efficiency that exceeds the sum of its parts—“1 + 1 > 2.”
Technology builds safeguards, putting an end to high-risk construction.
In underground engineering, safety is of paramount importance. Faced with high-risk areas such as collapses and high‑gas environments, the ZXZY200 is equipped with an intelligent remote‑control system that enables operators to perform remote operations via a multi‑degree‑of‑freedom robotic arm—without entering hazardous zones—thereby establishing a robust safety barrier. Meanwhile, its integrated automated drilling system can sense the surrounding environment and monitor gas concentrations in real time, dynamically adjusting support and drilling parameters. This has boosted both construction safety and efficiency by 70%, making “unmanned, intelligent” construction a tangible reality.
Green and low-carbon—truly the indomitable spirit of a “tough guy”
While pursuing high efficiency, the ZXZY200 also balances eco‑friendly construction with robust performance. Equipped with a diesel‑electric hybrid powertrain, it seamlessly switches to all‑electric mode in tunnel environments, significantly cutting exhaust emissions and delivering energy savings of 15% to 20%. When tackling extremely hard rock formations, its high‑frequency hydraulic hammer delivers up to 6,000 impacts per minute, boosting drilling speed by 25% while reducing energy consumption by 10%, demonstrating unparalleled strength and durability.
The ZXZY200 double‑arm rock‑drilling rig from Zhengxun Heavy Industry is not merely a piece of heavy equipment; it is a tangible embodiment of the “safety, efficiency, and sustainability” principles that underpin modern tunnel engineering. Its exceptional stability and construction productivity even under demanding working conditions are helping China’s underground infrastructure projects reach new heights of intelligence and safety.
