Summary:
Construction of tunnels in complex geological conditions places higher demands on the operational range, safety performance, and overall efficiency of rock‑drilling equipment. The ZXZY200 double‑curved‑arm rock‑drilling rig from Zhengxun Heavy Industry, leveraging an innovative double‑curved‑arm hydraulic system, overcomes the operational limitations of conventional straight‑arm rigs, offering an efficient and reliable tunneling solution for large‑section tunnels, caverns, and drifts requiring drill‑and‑blast support.
Compared with traditional single‑arm equipment, the dual‑curved‑arm structure is the key highlight of this trolley. Zhengxun Heavy Industry’s dual‑curved‑arm design incorporates a biomimetic joint mechanism, enabling 360° rotation, pitch, and telescopic movements in multiple directions. This boosts the working coverage by more than 40%, significantly reducing the need for frequent repositioning and allowing large‑area hole‑drilling tasks to be completed without repeatedly moving the machine on site. Paired with a dual‑arm coordination system, the equipment supports simultaneous or alternating drilling, cutting cycle time by approximately 30%. In integrated support operations for caverns and tunnels, its flexibility and stability are fully leveraged.
The safety‑oriented design is tailored to the demanding conditions of high‑risk tunneling operations. Zhengxun Heavy Industry’s hyperbolic‑arm rock‑drilling rig is equipped with an intelligent remote‑control system, leveraging a multi‑degree‑of‑freedom robotic arm to perform remote tasks. In hazardous areas prone to collapses or high concentrations of gas, operators can remain safely away from the face while carrying out drilling, thereby mitigating on‑site risks at their source. Integrated environmental sensing and gas‑monitoring modules enable dynamic adjustment of support and drilling parameters, seamlessly embedding environmental monitoring into the construction workflow and reinforcing the tunneling operation’s safety safeguards.
The Zhengxun Heavy Industry hyperbolic‑arm rock‑drilling rig employs a diesel‑electric dual‑mode propulsion system. In tunnel environments, switching to pure electric mode reduces exhaust emissions, improves the working conditions inside the tunnel, and delivers energy savings of 15–20%. The diesel mode enables long‑distance relocation, while the two power sources can be seamlessly switched as needed, balancing the demands of in‑tunnel construction with off‑site mobility. Equipped with a high‑frequency hydraulic hammer, the machine achieves an impact frequency of up to 6,000 blows per minute, boosting drilling speeds in hard‑rock conditions by 25% while cutting energy consumption by 10%. Even when tackling highly abrasive rock formations, it strikes an optimal balance between excavation efficiency and energy‑use control.
Zhengxun Heavy Industry’s hyperbolic‑arm rock‑drilling rig features automatic drilling capabilities and, when paired with programmable modules, lowers the barrier to entry for drilling operations. On‑site personnel can adjust operating parameters based on geological conditions, minimizing construction deviations caused by variations in manual execution, ensuring borehole quality, and making drilling‑and‑support operations in complex geological settings more controllable.
From its flexible bionic curved-arm structure and remote‑controlled safety protection to its dual‑power energy‑saving system, the ZXZY200 twin‑curved‑arm rock‑drilling rig addresses the real pain points of tunnel construction sites. Rather than chasing superficial specifications, it focuses on three core priorities—operational coverage, construction safety, and energy efficiency—and is suitable for a wide range of projects, including tunnels, underground chambers, and mine roadways. In complex geological conditions and high‑risk working environments, it stands as rock‑drilling equipment that balances efficiency, safety, and cost‑effectiveness.
