The LG312K The intelligent arch integrated trolley, LG312K, seamlessly combines multiple advanced processes such as surveying, setting out, under-excavation operation, arch installation, mesh and connecting bar welding (optional), and explosive charging. This state-of-the-art system can accomplish one-time tunnel excavation and arch installation without requiring machine relocation. Equipped with an engineering chassis and a dual power system (diesel and electric), it offers a compact design with a short wheelbase and robust traction, ensuring unparalleled flexibility and maneuverability across diverse and challenging tunnel conditions. The boom, which can be controlled wirelessly and manually, allows for precise and easy operation, ensuring not only safety but also speed, high efficiency, and energy conservation.
Expandable Man Basket: Our equipment features a versatile expandable man basket, designed to provide a larger operating space that can comfortably accommodate 3-6 individuals. This innovation is especially useful for loading explosives and anchor rods, enhancing both safety and operational efficiency.
High Efficiency: The LG312K utilizes a sophisticated three-arm structure, three grippers, and three hanging baskets, adaptable to various construction methods including full sections, two-step, and three-step processes. Remarkably, all vertical frame construction processes can be completed within approximately one hour, showcasing the system's unmatched efficiency.
Installation of Precast Arch: Our company’s patented multi-frame precast arch technology (Patent No. ZL202022537953.5) significantly reduces working duration and diminishes the risks associated with hazardous working faces. This innovation leads to a substantial improvement in overall construction efficiency.
Reduction of Number of Operators: With the LG312K, the entire construction operation can be efficiently managed by just 3-4 people, a considerable reduction compared to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: The LG312K is equipped with an integrated breaking hammer, allowing for seamless under-excavation operations immediately after arch installation.
Small Overall Dimensions: Designed with a lightweight structure, the LG312K boasts small overall dimensions, making it perfectly suited for small section construction conditions.
Equipment Informatization (Optional): The LG312K supports sophisticated informatization features, including cluster management, positioning functions, video monitoring, interphone capabilities, pre-alarm functions, comprehensive data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control functionalities.
