Audited Supplier The LGM312N The LGM312N intelligent integrated arch anchor trolley stands as a marvel of engineering innovation. Designed with an advanced engineering chassis, it features a dual anchor system, four-wheel steering, and four-wheel drive capabilities. This cutting-edge machine supports two-way driving, making it exceptionally versatile. Its diesel-electric dual power system ensures seamless operations under electric power, while also providing a failsafe diesel-powered emergency mode. Equipped with a sophisticated three-arm remote control, it guarantees precise positioning for prefabricated arch frame installations, various benching methods, and crucial adjustments. The arch frame excels in handling under-excavation, welding operations, and offers unparalleled flexibility within tunneling environments.
Functional integration: The intelligent integrated arch anchor trolley is a powerhouse of multi-process integration. It seamlessly combines measuring, point placement, under-excavation, arch frame installation, anchor net installation, advance support, system anchor construction, and optional anchor grouting-all into one cohesive operational unit.
Equipment digitization (Optional): The optional digitization package elevates the equipment with features like cluster management, precise positioning, video surveillance, walkie-talkie communication, pre/alarm functions, comprehensive data management, tunnel BIM technology, digital twin capabilities, and detailed construction reporting.
management, tunnel contour scanning, remote control, and an array of other advanced functionalities.
High efficiency: Showcasing an innovative three-arm, three-gripper, and three-basket structure, the LGM312N offers unmatched efficiency. The middle arm boasts a maximum lifting force of 3 tons, facilitating a complete construction cycle in approximately one hour.
Installation of prefabricated arch frames: Using our patented multi-frame prefabricated segmented assembly and folding techniques, the arch frames are efficiently prefabricated outside the tunnel. This strategic approach significantly reduces on-site labor time, minimizes exposure to hazardous conditions, and enhances overall safety and efficiency.
Dual anchor system: With a remarkable maximum drilling depth of 4.5m, the dual anchor system's left and right arm frames can simultaneously execute feet locking, system anchoring, and advance anchoring operations, ensuring robust support and stability.
Rotating deployable hanging basket: Equipped with a rotating hanging basket, the machine offers an expansive operating space ideal for the installation of explosives and anchor rods, further enhancing operational efficiency.
Optional grouting function: The optional grouting system expedites grouting operations post-anchor installation, making it an indispensable feature for swift and efficient construction workflows.
Less operating personnel: Thanks to its advanced automation, the entire construction process can be effectively managed by a reduced crew of just 3-4 individuals, as opposed to the traditional requirement of 8 or more personnel, drastically cutting labor costs and improving efficiency.
Auxiliary function integration: The LGM312N is equipped with auxiliary features like a breaker hammer and welding machine, enabling essential under-excavation processing and welding operations during the installation of the arch frame.
