Summary:
In complex geological tunneling projects—such as those in mining, highways, railways, water conservancy, and national defense—construction efficiency and safety often hinge on the adaptability and level of intelligence of the equipment. Zhengxun Heavy Industry’s ZXZY200 double‑curved‑arm rock‑drilling rig, built around an innovative “double‑curved‑arm hydraulic system,” overcomes the limitations of conventional single‑arm or straight‑arm designs, offering a groundbreaking solution for integrated drilling, blasting, and support operations in large‑section tunnels, caverns, and roadways. It truly delivers construction outcomes that are “widely applicable, highly efficient, and rock‑solidly reliable.”
The device’s “hyperbolic arm” design is not a simple additive; instead, it employs a biomimetic joint architecture to enable 360° rotation, pitch adjustment, and extension/retraction. This boosts the working envelope by more than 40% compared with conventional equipment, while significantly reducing the number of repositioning maneuvers and cutting single‑cycle operation time by up to 30%. In terms of dual‑arm coordinated control, the system features a hydraulic synchronization mechanism that supports simultaneous drilling or alternating operations, dramatically enhancing drilling efficiency. Leveraging a multi‑degree‑of‑freedom robotic arm, the equipment also enables remote operation, making it well suited for high‑risk environments such as collapse‑prone areas and zones with elevated gas concentrations, thereby reinforcing construction safety.
The Zhengxun Heavy Industry hyperbolic-arm rock‑drilling rig features a “diesel‑electric dual‑mode drive” that intelligently switches between power sources based on operating conditions: in tunnels, it automatically engages pure electric mode to reduce exhaust emissions and achieve significant energy savings; in outdoor or non‑electrified areas, it defaults to diesel mode to ensure continuous operation. Equipped with a high‑frequency hydraulic hammer boasting an impact rate of up to 6,000 blows per minute, the machine boosts drilling speed in hard rock by 25% while cutting energy consumption by 10%, delivering truly fast, precise, and efficient rock‑breaking performance.
Notably, the equipment integrates environmental sensing and gas‑monitoring control modules, enabling dynamic adjustment of support and drilling parameters and boosting both construction safety and efficiency by 70%. Its automated drilling capability simplifies operation and enhances precision, allowing it to handle even complex cross‑sections with ease.
The ZXZY200 hyperbolic-arm rock‑drilling rig from Zhengxun Heavy Industry is far more than a mere “drilling machine”; it is the central hub of tunnel construction, seamlessly integrating intelligent control, high‑efficiency rock breaking, and robust safety protection. Featuring an innovative design that tackles complex working conditions, dual‑mode power that balances environmental sustainability with extended operation, and an advanced smart system that ensures both safety and productivity, it is redefining the “new standard” for tunnel construction. For engineering teams that prioritize efficiency, safety, and intelligence, it is undoubtedly a trusted “dual‑engine powerhouse” for rock excavation.
