The LG312K The intelligent arch integrated trolley LG312K is a marvel of engineering, combining multiple processes seamlessly: surveying, setting out, under-excavation operation, arch installation, optional mesh and connecting bar welding, and explosive charging. This exceptional machine accomplishes one-time excavation and arch installation in tunnels without needing to move. Built on an engineering chassis with diesel and electric dual power systems, the LG312K boasts a short wheelbase, compact body, agile maneuverability, and outstanding traction, making it perfect for complex tunnel pavements. The boom offers both wireless remote control and manual control operations, ensuring ease of use, safety, speed, efficiency, and energy conservation.
Expandable Man Basket: Our equipment features a versatile expandable man basket, providing a spacious working area accommodating 3-6 people. Ideal for loading explosives and anchor rods.
High Efficiency: Featuring a three-arm structure, three grippers, and three hanging baskets, this advanced design supports full sections, two-step, and three-step construction methods. Every vertical frame construction process can be completed in approximately one hour.
Installation of Precast Arch: Leveraging our patented multi-frame precast arch technology (Patent No. ZL202022537953.5), we reduce working time and mitigate risks in dangerous working areas, substantially boosting construction efficiency.
Reduction of Number of Operators: Efficiently designed, the entire construction operation can be managed by just 3-4 operators, compared to the traditional requirement of 8 or more.
Auxiliary Function Integration: Equipped with a breaking hammer, the LG312K can immediately commence under-excavation once the arch is installed.
Small Overall Dimensions: The LG312K features a lightweight, compact design, making it ideal for small section construction conditions.
Equipment Informatization (Optional): Our system supports high-tech functionalities such as cluster management, positioning, video monitoring, intercom, pre-alarm, data management, BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control.
