The LG312K The innovative LG312K Intelligent Arch Integrated Trolley is a marvel of engineering that seamlessly combines multiple processes such as surveying, setting out, under-excavation, arch installation, mesh and connecting bar welding (optional), and explosive charging. This state-of-the-art machine can complete the entire tunnel excavation and arch installation in one go without the need for repositioning. Featuring an engineering chassis, this powerhouse comes equipped with a dual power system—diesel and electric—along with a short wheelbase and compact body for unparalleled flexibility and maneuverability. Its superb traction capabilities make it ideal for navigating various complex tunnel pavement conditions. The boom is controlled via a wireless remote and manual operation, ensuring smooth, safe, and highly efficient performance while conserving energy.
Expandable Man Basket: The equipment boasts an expandable man basket that offers a larger operating space, accommodating 3-6 people. This versatile basket can be used for loading explosives and anchor rods, providing enhanced operational capacity.
High Efficiency: Engineered for maximum efficiency, the LG312K features a three-arm structure, three grippers, and three hanging baskets. It is compatible with full sections, two-step, and three-step construction methods. Astonishingly, all construction processes of the vertical frame can be completed in just about one hour.
Installation of Precast Arch: Utilizing our patented multi-frame precast arch technology (Patent No. ZL202022537953.5), the LG312K significantly reduces the work duration and risks associated with dangerous working faces. This groundbreaking technology markedly improves construction efficiency.
Reduction of Number of Operators: Remarkably efficient, the entire construction operation can be executed 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 allows for under-excavation operations immediately after the arch installation, streamlining the construction process.
Compact Dimensions: Designed with a lightweight structure and compact overall dimensions, this vehicle is perfectly suited for small-section construction conditions.
Equipment Informatization (Optional): Embracing advanced technology, the LG312K supports a range of functionalities 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.
