The LG312K The Intelligent Arch Integrated Trolley System, model LG312K, revolutionizes tunnel operations by seamlessly combining surveying, under-excavation, arch installation, mesh and connecting bar welding (optional), and explosive charging—all without moving the machine. Built on an engineering chassis with a diesel-electric dual power system, this compact and nimble machine is engineered for complex tunnel conditions, offering exceptional traction. The boom, controlled via wireless remote or manually, ensures effortless and precise operation, which enhances safety, speed, efficiency, and energy savings.
Expandable Man Basket: Equipped with a spacious expandable man basket, this feature supports a larger working area and can comfortably accommodate 3 to 6 personnel. Ideal for tasks such as loading explosives and anchor rods.
High Efficiency: Featuring a three-arm structure with three grippers and hanging baskets, the system supports full sections, two-step, and three-step construction methods. It completes vertical frame construction processes in roughly one hour, maximizing operational efficiency.
Installation of Precast Arch: Our patented multi-frame precast arch technology (Patent No. ZL202022537953.5) minimizes working duration and construction risks at perilous working faces, thereby substantially enhancing construction efficiency.
Reduction of Number of Operators: This innovative system enables the entire construction operation to be executed by just 3-4 operators, compared to 8 or more required in traditional setups.
Auxiliary Function Integration: The equipment includes a breaking hammer, facilitating under-excavation operations immediately after arch installation.
Small Overall Dimensions: Designed with a lightweight framework and compact dimensions, making it perfect for small section construction environments.
Equipment Informatization (Optional): Supports advanced features like cluster management, positioning, video monitoring, interphone, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control, enhancing operational oversight and efficiency.
