Audited Supplier The LGM312N The intelligent integrated arch anchor trolley, LGM312N, boasts an advanced engineering chassis equipped with a sophisticated dual anchor system. Experience unparalleled functionality with four-wheel steering, four-wheel drive, and bi-directional operation. The diesel-electric dual power system ensures seamless transitions between electric construction modes and diesel-powered emergency functions. With its three-arm remote control, it expertly handles prefabricated arch frame installations, various benching operations, and precise positioning adjustments. This trolley excels in under-excavation and welding tasks during installation, delivering unmatched flexibility within the tunnel.
Functional Integration: The LGM312N merges multiple processes into a single, highly efficient workflow. From measuring and placing points, under-excavation, arch frame installation, and anchor net setup to advance support, system anchor construction, and anchor grouting (optional), this equipment does it all.
Equipment Digitization (Optional): Includes advanced features such as cluster management, precise positioning, video surveillance, walkie-talkie communication, pre/alarm functions, and comprehensive data management. Embrace the future with tunnel BIM technology, digital twins, construction reporting management, tunnel contour scanning, and remote control capabilities.
Management, tunnel contour scanning, remote control, and additional functionalities.
High Efficiency: Featuring an innovative three-arm, three-gripper, and three-basket design, the LGM312N ensures maximum operational efficiency. The middle arm boasts a lifting force of 3 tons, completing the entire construction process in approximately one hour.
Installation of Prefabricated Arch Frames: Our patented multi-frame prefabricated segmented assembly and multi-frame prefabricated folding arch frame installation techniques streamline external production. This approach significantly reduces working time on hazardous surfaces, minimizes construction safety risks, and enhances overall efficiency.
Dual Anchor System: Achieve impressive drilling depths up to 4.5 meters. The left and right arm frames perform feet locking, system anchoring, and advance anchoring operations concurrently, maximizing productivity.
Rotating Deployable Hanging Basket: Equipped with a spacious rotating hanging basket, the LGM312N offers an expansive workspace ideal for installing explosives and anchor rods efficiently.
Optional Grouting Function: The optional grouting system facilitates rapid grouting operations post-anchor installation, enhancing speed and efficiency.
Reduced Personnel Requirement: Streamline your operations with a minimal crew of just 3-4 individuals, compared to the 8 or more traditionally needed, enhancing resource efficiency and reducing labor costs.
Auxiliary Function Integration: The LGM312N is equipped with a breaker hammer and welding machine, capable of performing under-excavation processing and welding during arch installations, further augmenting its multifunctional capabilities.
