Audited Supplier The LG312M The intelligent integrated arch frame trolley, LG312M, masterfully integrates multiple processes such as measuring and placing points, under-excavation operations, arch frame installation, welding mesh, and connecting ribs. During the one-time excavation of a double-track tunnel, the arch frame installation can be seamlessly completed without the need to move the machine. The entire vehicle is built on an engineering chassis, boasts diesel-electric dual power systems, and features a two-way driving platform structure. This innovative machine offers exceptional driving performance, ensuring adaptability to various complex tunnel road conditions. The arm frame utilizes both wireless remote control and manual control operations, allowing for precise and effortless control of the robotic arm. It stands out for its speed, efficiency, energy-saving capabilities, and safety.
Equipment Digitization (Optional): This feature includes cluster management, positioning function, video surveillance, walkie-talkie function, pre/alarm function, data management function, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, remote control, and other advanced functionalities.
Expandable Hanging Basket: The equipment is fitted with an expandable hanging basket, providing a larger operating space ideal for installing explosives and anchor rods.
High Efficiency: Featuring a three-arm, three-gripper, and three-basket structure, the maximum lifting force of the middle arm is a robust 3 tons. It supports various construction methods, including full-section, two-benching, and three-benching. The entire setup can be accomplished in roughly an hour, greatly enhancing efficiency.
Installation of Prefabricated Arch Frames: Utilizing our company's patented multi-frame prefabricated segmented assembly and folding arch frame installation techniques, arch frames are produced outside the tunnel. This innovative approach significantly reduces the time required to work on dangerous surfaces, lowers construction safety risks, and substantially boosts overall efficiency.
Reduced Operating Personnel: Traditionally requiring 8 or more personnel, the entire construction operation can now be efficiently managed by just 3-4 people.
Auxiliary Function Integration: The equipment is equipped with a breaker hammer and welding machine, enabling under-excavation processing and welding operations during arch installation.
Compact Design: With its lightweight design and compact size, the vehicle is perfectly suited for small-section construction conditions.
