The LG312K The intelligent arch integrated trolley, model LG312K, revolutionizes tunnel construction by seamlessly integrating multiple processes such as surveying and setting out, under-excavation operation, arch installation, mesh and connecting bar welding (optional), and explosive charging. This versatile machine completes both one-time excavation and arch installation without needing to be moved. Featuring an engineering chassis, a diesel-electric dual power system, and a compact, maneuverable design with a short wheelbase, it is engineered for high performance in complex tunnel environments. The boom, controlled by wireless remote or manual operation, ensures ease of use, safety, efficiency, and energy conservation.
Expandable Man Basket: This equipment is equipped with an expandable man basket, offering a larger operating space that can accommodate 3-6 personnel. It’s ideal for loading explosives and anchor rods, enhancing operational efficiency and safety.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, the LG312K supports full-section, two-step, and three-step construction methods. Vertical frame construction processes can be completed in approximately one hour, significantly boosting productivity.
Installation of Precast Arch: Utilizing our patented multi-frame precast arch technology (Patent No. ZL202022537953.5), this system reduces the working duration and minimizes construction risks at dangerous working faces, substantially improving construction efficiency.
Reduction of Number of Operators: The entire construction operation can be efficiently managed by a team of just 3-4 people, compared to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: The equipment includes a breaking hammer, enabling under-excavation operations to commence immediately after arch installation.
Small Overall Dimensions: Designed with a lightweight, compact structure, the entire vehicle is perfectly suited for small section construction conditions.
Equipment Informatization (Optional): The system supports 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.
