Audited Supplier Introducing the LG312M: Pinnacle of Intelligent Engineering Our state-of-the-art LG312M intelligent integrated arch frame trolley seamlessly combines multiple sophisticated processes including precise measuring and point placement, meticulous under-excavation operations, seamless arch frame installation, robust mesh welding, and secure rib connections. Designed to complete the entire installation of arch frames in one seamless excavation for double-track tunnels, the machine eliminates the need for repositioning. Boasting a rugged engineering chassis and dual diesel-electric power systems alongside a versatile two-way driving platform, this machine delivers superior driving performance and adeptly navigates complex tunnel conditions. The arm frame, operated via wireless remote control or manual control, ensures precise and effortless movement, embodying speed, efficiency, energy conservation, and safety.
Optional Equipment Digitization for Enhanced Functionality: Our equipment digitization suite offers an array of advanced features, including cluster management, precise positioning functions, comprehensive video surveillance, seamless walkie-talkie integration, proactive alarm systems, data management capabilities, BIM technology, digital twin modeling, construction report management, precise tunnel contour scanning, and advanced remote control functionalities.
Versatile Expandable Hanging Basket: Equipped with an innovative expandable hanging basket, our equipment provides a spacious operating environment ideal for the installation of explosives and anchor rods, ensuring versatility and efficiency in various applications.
Superior Efficiency and Performance: With a robust three-arm, three-gripper, and three-basket structure, the LG312M features a middle arm with a maximum lifting capacity of 3 tons. It supports diverse construction methods such as full-section, two-benching, and three-benching, allowing for rapid setup within approximately one hour.
Seamless Installation of Prefabricated Arch Frames: Employing our patented multi-frame prefabricated segmented assembly and folding techniques, the LG312M facilitates the production of arch frames outside the tunnel, significantly reducing on-site working time and enhancing construction safety, while dramatically boosting overall efficiency.
Streamlined Operations with Minimal Personnel: Our advanced construction operations can be efficiently conducted by a team of just 3-4 individuals, a stark contrast to traditional methods that require 8 or more personnel, thereby optimizing labor costs and productivity.
Comprehensive Auxiliary Function Integration: The LG312M is equipped with an integrated breaker hammer and welding machine, providing the capability to perform under-excavation processing and welding operations during arch installation, ensuring all-in-one functionality.
Compact and Adaptable Design: Boasting a lightweight design and compact overall size, our vehicle is perfectly suited for small-section construction conditions, ensuring adaptability and ease of use in confined spaces.
