Summary:
Behind every tunnel that cuts through mountains and valleys, arch‑support installation has always been a critical step in ensuring the stability of the surrounding rock and safeguarding construction safety. Yet traditional methods have long relied on manual labor: a dozen or so workers huddle around bulky steel arches, pushing and prying in narrow, damp tunnels, with each set taking three to four hours to complete. High labor intensity, low efficiency, and elevated safety risks are not only a major source of hardship for frontline workers but also a bottleneck that hinders efforts to accelerate tunnel‑construction progress.
The launch of the ZXGJ3000 three‑arm arch‑support installation carriage by Zhengxun Heavy Industry is a solid response to the demands of our times, driven by robust technological innovation. Featuring an innovative three‑arm design, the equipment significantly expands its operational coverage. From equipment mobilization to the completion of installing three arch supports, it can be accomplished in just 4 to 5 workers and 1.5 hours. Compared with conventional construction methods, this approach boosts efficiency by more than 50% while cutting labor requirements by half. This is not merely a matter of numerical improvement; it represents a tangible transformation—faster tunnel breakthroughs and safer working conditions for every construction professional.
Multi‑functionality is another key highlight of this mobile platform. In addition to core arch‑support installation, it can simultaneously perform mesh‑panel laying, rock‑bolt installation, auxiliary blasting, and operations on elevated work platforms, among other tasks. One single machine replaces the previously cumbersome process that required multiple pieces of equipment to take turns, eliminating the need for frequent equipment changes and transforming support‑construction work from a “physical labor” task into a “technical endeavor.”
In terms of detailed design, the ZXGJ3000 closely mirrors real-world tunnel construction scenarios. It features a high‑strength, lightweight boom that delivers robust load‑bearing rigidity while maintaining exceptional maneuverability. Equipped with a China IV‑compliant engine, it significantly reduces exhaust emissions within tunnels, helping to improve the confined working environment. Its modular, integrated compact layout ensures a small, agile footprint, enabling effortless turning and passage even in narrow tunnels with limited space. The machine is fitted with multiple work platforms that effectively isolate the working area from hazardous zones, minimizing the risk of personnel being exposed to falling rock or mechanical impacts.
From efficiency upgrades to workforce optimization, and from eco‑friendly design to scenario‑specific adaptability, the Sanbei Arch Support Installation Trolley by Zhengxun Heavy Industry eschews flashy gimmicks in favor of grounding every design feature in the real‑world demands of tunnel construction. Combining safety, efficiency, labor savings, and cost‑effectiveness, it stands as a robust and reliable piece of equipment for modern tunnel support operations.
