The LG312K The intelligent arch integrated trolley, LG312K, masterfully combines multiple processes like surveying and setting out, under-excavation operation, arch installation, mesh and connecting bar welding (optional), and explosive charging. It excels by completing a one-time excavation and arch installation of the tunnel without repositioning the machine. With an engineering chassis, dual diesel and electric power system, and a compact, flexible design, this equipment is ideally suited for navigating complex tunnel pavement conditions. The wireless remote control and manual control of the boom ensure seamless handling. This results in a safe, speedy, highly efficient, and energy-saving operation.
Expandable Man Basket: The equipment boasts an expandable man basket, offering a larger operating space to accommodate 3-6 personnel. It's perfect for loading explosives and anchor rods, enhancing the versatility and safety of operations.
High Efficiency: With a three-arm structure, three grippers, and three hanging baskets, this equipment can be utilized in full sections, two-step, three-step, and other construction methods. The vertical frame construction processes can be completed in approximately one hour, significantly boosting operational efficiency.
Installation of Precast Arch: Our company’s independently developed patented technology for multi-frame precast arch (Patent No. ZL202022537953.5) substantially reduces both working duration and construction risk at dangerous workfaces, thereby significantly increasing construction efficiency.
Reduction of Number of Operators: This advanced construction operation can be efficiently managed by just 3-4 people, unlike traditional methods that require 8 or more operators.
Auxiliary Function Integration: Equipped with a breaking hammer, the under-excavation operation can be initiated immediately after the arch is installed, providing seamless workflow integration.
Small Overall Dimensions: The lightweight design of the entire vehicle, featuring small overall dimensions, makes it perfectly suitable for small section construction conditions, ensuring ease of maneuverability and practicality.
Equipment Informatization (Optional): The equipment supports an array of advanced functionalities including cluster management, positioning, video monitoring, interphone, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control, making it a cutting-edge solution for modern tunneling projects.
