Summary:
As a core hub in transportation infrastructure development, tunnel engineering places the installation of arch supports at the forefront of ensuring both surrounding-rock stability and overall construction safety. Zhengxun Heavy Industry, with its deep expertise in tunnel-construction equipment, has launched a groundbreaking three-boom arch-support-erection trolley that redefines support-construction workflows through intelligent design and breaks industry barriers with specialized performance, thereby providing critical equipment support for high-quality tunnel construction.
The Zhengxun Heavy Industry Three-Arm Arch Support Installation Trolley is a specialized, intelligent piece of equipment for tunnel support, precisely tailored to accommodate a wide range of arch types, including steel sections and lattice arches. The equipment comprehensively addresses construction requirements under various excavation conditions, breaking the limitations of single-function machinery and enabling an efficient “multi-functional-in-one” operation mode. It integrates functions such as arch installation, mesh placement, and rock bolt drilling, making it adaptable to diverse tunnel construction needs and significantly enhancing the continuity and efficiency of the construction process.
In terms of operational efficiency and safety management, the Zhengxun Heavy Industry three-arm arch support installation trolley has achieved breakthrough performance through its innovative structural design. Its expanded working envelope precisely meets the diverse support requirements of tunnel construction, significantly shortening the cycle time for each individual operation. Moreover, the trolley’s streamlined staffing configuration requires only a small number of operators to complete the entire workflow, substantially reducing labor input compared with traditional methods. By markedly decreasing the amount of time personnel spend in high-risk work zones, the equipment helps mitigate safety risks at the very source of the operational process. Equipped with a high-strength, lightweight boom constructed from high-performance materials, the trolley achieves weight reduction without compromising load-bearing stiffness, thereby enhancing its maneuverability and flexibility. This enables the equipment to move and operate with ease even in the confined spaces of tunnels, fully meeting the demands of all scenarios in complex tunnel environments.
Zhengxun Heavy Industry’s three-arm arch support installation trolley features a modular, integrated compact layout that optimizes space utilization and enables flexible steering and adaptation, easily meeting the passage and operational requirements in narrow tunnel environments and significantly enhancing the equipment’s adaptability to diverse application scenarios. 
Zhengxun Heavy Industry’s three-arm arch support installation trolley replaces hazardous manual operations with mechanized, intelligent solutions, leverages technological innovation to upgrade tunnel support construction, fortifies the project’s safety safeguards through superior performance, and aligns with industry development trends by embracing efficient and environmentally friendly practices—thereby achieving dual improvements in safety management and construction efficiency.
