The LG312K The LG312K Intelligent Arch Integrated Trolley masterfully combines multiple complex processes including surveying and setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), explosive charging, and more. This powerhouse is designed to accomplish one-time excavation and arch installation in tunnels without the need to reposition the machine. Featuring an engineering chassis, dual power system (diesel and electric), a short wheelbase, compact body, and unparalleled flexibility, the LG312K is perfectly suited for diverse and challenging tunnel environments. The boom is managed via both wireless remote control and manual control, ensuring precise and safe operations while delivering exceptional speed, efficiency, and energy savings.
Expandable Man Basket: The LG312K includes an expandable man basket, offering a more spacious operating area that can hold 3-6 individuals. This feature is ideal for loading explosives and anchor rods, facilitating safer and more efficient operations.
High Efficiency: With a three-arm structure, three grippers, and three hanging baskets, the LG312K is designed for full section, two-step, and three-step construction methods. Remarkably, all vertical frame construction processes can be completed in about an hour, ensuring rapid and efficient project completion.
Installation of Precast Arch: Utilizing our company's patented technology (multi-frame precast arch, patent No. ZL202022537953.5), the LG312K significantly reduces the duration and risk associated with dangerous working faces, vastly enhancing construction efficiency.
Reduction of Number of Operators: The LG312K allows the complete construction operation to be performed by just 3-4 operators, compared to the traditional requirement of 8 or more, thereby significantly cutting down labor costs and increasing efficiency.
Auxiliary Function Integration: Equipped with a breaking hammer, the LG312K enables seamless under-excavation operations immediately after arch installation, streamlining the workflow and enhancing productivity.
Small Overall Dimensions: Designed with a lightweight and compact form factor, the LG312K is perfectly suited for small section construction conditions, offering unmatched versatility and maneuverability.
Equipment Informatization (Optional): The LG312K supports a host of advanced features such as cluster management, positioning, video monitoring, interphone communication, pre-alarm notifications, data management, tunnel BIM technology, digital twin capabilities, construction report management, tunnel contour scanning, and remote control functionalities.
