The LG312K The LG312K intelligent arch integrated trolley is a marvel of engineering, seamlessly combining processes like surveying, setting out, under-excavation, arch installation, mesh and connecting bar welding (optional), and explosive charging. This incredible machine completes an entire tunnel excavation and arch installation in one go, eliminating the need to move the machine. Featuring an engineering chassis with a diesel and electric dual power system, its compact body and flexible maneuverability make it perfect for various complex tunnel conditions. The boom can be operated via wireless remote control or manually, ensuring ease of use, safety, speed, high efficiency, and energy conservation.
Expandable Man Basket: Equipped with an expandable man basket, this machinery provides a spacious operating area that can accommodate 3-6 personnel. Ideal for loading explosives and anchor rods, it significantly enhances operational efficiency.
High Efficiency: The advanced three-arm structure with three grippers and three hanging baskets allows for versatile use in full sections, two steps, three steps, and other construction methods. This design ensures that all vertical frame construction processes are completed in roughly one hour, optimizing productivity.
Installation of Precast Arch: Utilizing our company’s patented multi-frame precast arch technology (Patent No. ZL202022537953.5), the LG312K significantly shortens the work duration and reduces construction risks in hazardous zones, thereby greatly boosting construction efficiency.
Reduction of Number of Operators: This innovative machine streamlines the entire construction process, requiring only 3-4 operators compared to the traditional need for 8 or more, making it highly efficient.
Auxiliary Function Integration: The LG312K is equipped with a breaking hammer, enabling under-excavation operations immediately after arch installation, enhancing workflow continuity.
Small Overall Dimensions: Designed for lightweight and compact dimensions, the LG312K is ideal for small section construction environments, offering unparalleled adaptability.
Equipment Informatization (Optional): The LG312K supports a host of advanced features including cluster management, positioning, video monitoring, interphone function, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control, setting a new standard in tunnel construction technology.
