Summary:
Tunneling efficiency has long been a core challenge in rail transit and highway infrastructure projects. Faced with complex working conditions—such as full-face excavation, the bench method, and invert construction—conventional construction equipment often struggles to adapt, making it difficult to meet the demands of multi‑process, coordinated operations. The ZXZY210 two‑arm rock‑drilling rig from Zhengxun Heavy Industry is specifically designed for medium‑ and large‑scale tunneling projects. With its robust, reliable hardware configuration, it overcomes the challenges of multi‑method construction, delivering a practical and highly efficient solution for mechanized tunneling.
Power performance determines the equipment’s capability in foundation construction. The Zhengxun Heavy Industry ZXZY210 is equipped with a high‑power China IV‑compliant engine, balancing robust power output with fuel‑efficiency benefits. Under prolonged, continuous rock‑drilling conditions, it delivers stable power and achieves economical, efficient fuel consumption. While ensuring strong construction performance, it also better meets current environmental emission standards, making its total cost of ownership more manageable over extended operations.
As a full‑method‑compatible rock‑drilling rig, it transcends the limitations of single‑purpose construction scenarios, seamlessly handling everything from full‑face tunnel excavation and bench‑method advancing to invert‑arch construction. In medium‑ and large‑scale tunnel projects, when two units operate side by side in coordinated fashion, their collaborative advantages are further amplified, significantly boosting face‑drilling productivity, shortening the duration of each advance cycle, and meeting the demands for standardized, accelerated construction of high‑speed rail and highway tunnels.
The control system and chassis design are meticulously tailored to the tunnel’s narrow, complex working environment. The equipment supports both local operation and remote‑control modes, allowing operators to seamlessly switch between them based on site safety conditions, thereby enhancing operational flexibility. The integral chassis features a front‑axle dual‑tire configuration, delivering a robust body structure that ensures stable handling on uneven tunnel surfaces. This design also improves steering and maneuverability, reducing equipment displacement and wear while ensuring uninterrupted construction progress.
The core drilling boom features a dual-rotation structure, which is essential for ensuring drilling accuracy and stability. With its flexible motion and rapid positioning response, the dual-rotation boom significantly enhances the efficiency of hole‑placement and alignment. The machine body is equipped with an integrated angle‑display function, enabling operators to intuitively monitor drilling angles, precisely manage under‑excavation and over‑excavation issues, reduce post‑construction rework, minimize unnecessary material and labor costs, and improve tunnel‑lining quality.
From powertrain and operating-condition optimization to the undercarriage, boom structure, and intelligent assistance features, the ZXZY210 twin-boom rock‑drilling rig eschews unnecessary frills; every design element is grounded in the real‑world demands of tunnel construction sites. As infrastructure projects increasingly embrace mechanization and standardization, a versatile, easy‑to‑operate, high‑precision drilling machine can deliver tangible improvements in quality and efficiency for construction teams.
Zhengxun Heavy Industry refines its products based on the frontline needs of tunnel construction. The ZXZY210 twin-arm rock drilling rig, with its well-balanced and reliable overall performance, has become a premium choice for drilling operations in medium- and large-scale tunnel projects, helping to advance infrastructure initiatives efficiently and safely.
