Audited Supplier The LG312M The intelligent integrated arch frame trolley, LG312M, revolutionizes tunneling with seamless integration of processes such as measuring and placing points, under-excavation operations, arch frame installation, welding mesh, and connecting ribs. Designed for efficiency, it completes double-track tunnel excavations without needing to reposition the machine. Its robust engineering chassis, diesel-electric dual power systems, and two-way driving platform ensure superior driving performance, adapting to complex tunnel road conditions effortlessly. The arm frame's wireless and manual control operations allow precise, agile movement, delivering fast, efficient, energy-saving, and safe operations.
Equipment digitization (Optional): Our advanced digitization options include cluster management, precise positioning, video surveillance, reliable walkie-talkie, intelligent pre/alarm function, data management, BIM technology, digital twin modeling, comprehensive construction report management, tunnel contour scanning, and remote control capabilities.
Expandable hanging basket: The equipment features an expandable hanging basket, providing ample operating space ideal for installing explosives and anchor rods.
High efficiency: Innovatively designed with a three-arm, three-gripper, and three-basket structure, it boasts a middle arm lifting force of 3 tons. Adaptable to various construction methods, such as full-section, two-benching, and three-benching, it facilitates rapid setup in approximately an hour.
Installation of prefabricated arch frames: Employing our patented multi-frame prefabricated segmented assembly and folding arch frame installation techniques, the arch frames are produced outside the tunnel. This approach dramatically reduces time required on hazardous surfaces, enhancing safety and efficiency.
Less operating personnel: With streamlined operations, a team of only 3-4 operators can complete tasks that traditionally required 8 or more, significantly reducing manpower needs.
Auxiliary function integration: The equipment is outfitted with a breaker hammer and welding machine, empowering it to perform under-excavation processing and welding operations seamlessly during arch installation.
Small overall size: Crafted with a lightweight design, the vehicle's compact size makes it perfectly suited for small-section construction conditions.
