Audited Supplier The LGM312U Our intelligent integrated arch anchor trolley, model LGM312U, boasts an advanced engineering chassis coupled with a reliable single anchor system. Designed with four-wheel steering and drive, and supporting two-way navigation, this machine offers unparalleled versatility. The dual power system—diesel-electric—ensures seamless electric construction with diesel backup for emergencies. Its innovative three-arm remote control excels in installing prefabricated arch frames, adapting various benching methods, and ensuring precise positioning. The trolley's capability extends to under-excavation and welding during arch frame installation, maintaining exceptional flexibility within the tunnel.
Functional integration: This state-of-the-art equipment integrates multiple processes such as measuring, under-excavation, arch frame installation, advance support, system anchor construction, optional anchor grouting, and anchor net installation, all within a single unit.
Equipment digitization (Optional): Optional digital features include cluster management, precise positioning, video surveillance, walkie-talkie communication, pre/alarm notifications, comprehensive data management, BIM technology, digital twin applications, detailed construction reports, tunnel contour scanning, and remote control capabilities.
management, tunnel contour scanning, remote control and other functions.
High efficiency: Built with a robust three-arm, three-gripper, and two-basket system, the middle arm's lifting capacity peaks at 2 tons. The entire construction process is remarkably efficient, often completed within just one hour.
Installation of prefabricated arch frames: Utilizing our patented multi-frame prefabricated segmented assembly and folding techniques, arch frames are pre-produced outside the tunnel. This innovation minimizes time spent on hazardous surfaces, enhancing safety and significantly boosting efficiency.
tunnel. This reduces the required working time on dangerous surfaces and construction safety risks, and greatly improves overall efficiency.
Single anchor system: The single anchor system features a maximum drilling depth of 4.5m, enabling the middle arm to perform feet locking, system anchoring, and advance anchoring with precision.
Expandable hanging basket: Equipped with an expandable hanging basket, this machine offers ample operating space, ideal for installing explosives and anchor rods efficiently.
Optional grouting function: The optional grouting system facilitates swift and effective grouting operations post-anchor installation, streamlining the construction process.
Less operating personnel: Amazingly, the entire operation requires only 3-4 personnel, compared to the traditional need for 8 or more, reflecting significant labor efficiency improvements.
Auxiliary function integration: Integrated auxiliary functions include a breaker hammer and welding machine, making under-excavation processing and welding during arch installation both seamless and efficient.
