The LG312K The intelligent arch integrated trolley, LG312K, revolutionizes tunnel construction by seamlessly incorporating multiple processes, including surveying, setting out, under-excavation, arch installation, mesh and connecting bar welding (optional), and explosive charging. This advanced machine completes tunnel excavation and arch installation in a single setup without needing to be moved. Designed with an engineering chassis, it boasts a dual power system (diesel and electric), a short wheelbase, compact body, and superb flexibility and traction, making it ideal for complex tunnel conditions. The boom offers both wireless remote control and manual operation for easy maneuvering, ensuring safety, speed, efficiency, and energy savings.
Expandable Man Basket: Equipped with an expandable man basket, this machine provides a spacious operating area that can comfortably hold 3-6 people, perfect for loading explosives and anchor rods.
High Efficiency: The innovative three-arm structure, equipped with three grippers and three hanging baskets, supports various construction methods including full sections, two-step, and three-step processes. Remarkably, all vertical frame construction processes can be completed in approximately one hour, optimizing productivity.
Installation of Precast Arch: Utilizing our patented multi-frame precast arch technology (Patent No. ZL202022537953.5), this equipment minimizes construction duration and reduces risks associated with dangerous working environments. This advancement significantly boosts construction efficiency.
Reduction of Number of Operators: This sophisticated system allows the entire construction operation to be executed by just 3-4 people, compared to the traditional requirement of 8 or more, thereby enhancing operational efficiency and reducing labor costs.
Auxiliary Function Integration: The equipment features a breaking hammer, enabling under-excavation operations to commence immediately after the arch installation, thereby streamlining the workflow.
Compact Dimensions: Designed with a lightweight and compact structure, this machine is perfectly suited for small section construction environments, offering unparalleled adaptability.
Advanced Informatization (Optional): This state-of-the-art equipment supports a range of advanced features including cluster management, positioning, video monitoring, interphone communication, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control, enhancing overall project management and oversight.
