The LG312K The intelligent arch integrated trolley, known as the LG312K, revolutionizes tunnel construction by seamlessly integrating multiple processes including surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging. This groundbreaking equipment is designed to complete one-time excavation and arch installation without repositioning. Its engineering chassis boasts a dual power diesel-electric system, short wheelbase, compact body, and superb traction, making it ideal for complex tunnel conditions. The boom, operated via wireless remote control and manual control, ensures ease of maneuverability, safety, high efficiency, and energy conservation.
Expandable Man Basket: The LG312K features an expandable man basket providing a larger operating space that accommodates 3-6 people. This versatile basket can be used for loading explosives and anchor rods, significantly enhancing operational efficiency.
High Efficiency: The equipment utilizes a three-arm structure with three grippers and three hanging baskets, adaptable for full sections, two-step, and three-step construction methods. Remarkably, all vertical frame construction processes can be completed in approximately one hour, maximizing productivity.
Installation of Precast Arch: Our patented multi-frame precast arch technology (Patent No. ZL202022537953.5) dramatically reduces working duration and construction risks at dangerous workfaces, thereby greatly enhancing construction efficiency.
Reduction of Number of Operators: Thanks to its advanced design, the entire construction operation can be efficiently managed by just 3-4 people, compared to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: Equipped with a breaking hammer, the LG312K enables under-excavation operations to commence immediately after arch installation, streamlining the construction process.
Small Overall Dimensions: Designed with a lightweight, compact structure, the LG312K is perfectly suited for small section construction conditions, offering unparalleled versatility.
Equipment Informatization (Optional): The LG312K supports advanced features including cluster management, positioning, video monitoring, interphone, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, remote control, and more, paving the way for smart construction management.
