Audited Supplier The LG312M The intelligent integrated Arch Frame Trolley, model LG312M, embodies state-of-the-art technology, synthesizing numerous functions such as precise measuring and point placement, under-excavation tasks, arch frame installation, mesh welding, and rib connection. This innovative trolley allows for the seamless installation of arch frames within double-track tunnels without necessitating machine repositioning. Engineered with a robust chassis and a versatile diesel-electric dual power system, it features a two-way driving platform, offering exceptional mobility and adaptability to diverse and complex tunnel conditions. The advanced arm frame, controlled via both wireless remote and manual operations, ensures precise and effortless maneuvering of the robotic arm, boasting remarkable efficiency, energy conservation, and safety.
Equipment Digitization (Optional): Equip your operations with cutting-edge digital capabilities, including cluster management, precise positioning, comprehensive video surveillance, walkie-talkie communication, preemptive and alarm functions, coherent data management, integration of tunnel BIM technology and digital twin, detailed construction report management, tunnel contour scanning, remote control, and more.
Expandable Hanging Basket: This equipment is outfitted with an expandable hanging basket, providing a spacious operating area ideal for the safe installation of explosives and anchor rods.
High Efficiency: The design features a three-arm, three-gripper, and three-basket configuration, with the middle arm capable of a maximum lifting force of 3 tons. It supports various construction methodologies, including full-section, two-benching, and three-benching, with the entire setup achievable within approximately one hour.
Installation of Prefabricated Arch Frames: Utilizing our patented multi-frame prefabricated segmented assembly and folding arch frame installation techniques, arch frames are pre-constructed outside the tunnel. This innovative approach minimizes time spent on hazardous surfaces, significantly enhancing construction safety and operational efficiency.
Reduced Workforce Requirement: This advanced system streamlines operations to be managed by just 3-4 personnel, contrasting sharply with traditional methods that demand 8 or more workers.
Auxiliary Function Integration: Equipped with both a breaker hammer and welding machine, this versatile equipment can undertake under-excavation processing and welding tasks during arch installation, enhancing operational flexibility.
Compact Design: The lightweight and compact design of the vehicle ensures its suitability for small-section construction environments, enhancing its adaptability and operational efficiency.
