Audited Supplier The LG312M The LG312M intelligent integrated arch frame trolley revolutionizes tunnel construction by seamlessly combining multiple processes: precise measuring and point placement, under-excavation operations, arch frame installation, welding mesh, and connecting ribs. This powerhouse of a machine completes arch frame installations during single-excavations of double-track tunnels without needing to relocate. Built on a robust engineering chassis, it features dual diesel-electric power systems and a bidirectional driving platform structure, ensuring exceptional performance even under complex tunnel conditions. Equipped with a wireless remote control and manual operation for the arm frame, it offers precise and effortless control, characterized by its speed, efficiency, energy-saving capabilities, and safety.
Equipment Digitization (Optional): Our state-of-the-art equipment comes with optional digitization features, including cluster management, positioning functions, video surveillance, walkie-talkie functionality, pre-alarm functions, data management capabilities, tunnel BIM technology, and digital twin. Additionally, it offers construction report management, tunnel contour scanning, remote control, and more.
Expandable Hanging Basket: The LG312M is equipped with an expandable hanging basket, providing a larger operational space ideal for installing explosives and anchor rods.
High Efficiency: Featuring a three-arm, three-gripper, and three-basket structure, the LG312M boasts a maximum lifting force of 3 tons for the middle arm. It supports various construction methods, including full-section, two-benching, and three-benching. Impressively, the entire setup can be completed in just about an hour.
Installation of Prefabricated Arch Frames: Our patented multi-frame prefabricated segmented assembly and folding arch frame installation techniques streamline the production of arch frames outside the tunnel. This innovation significantly reduces working time on hazardous surfaces, minimizes construction safety risks, and dramatically improves overall efficiency.
Less Operating Personnel: The LG312M enables a full construction operation with just 3-4 personnel, compared to the 8 or more typically required in traditional setups.
Auxiliary Function Integration: Integrated with auxiliary tools such as a breaker hammer and welding machine, the LG312M can handle under-excavation processing and welding operations efficiently during arch installation.
Small Overall Size: Designed to be lightweight and compact, the LG312M is perfectly suited for small-section construction conditions, ensuring adaptability and ease of use.
