The LG312K The intelligent arch integrated trolley, LG312K, revolutionizes tunnel construction by combining multiple processes into one seamless operation. This state-of-the-art machine is capable of surveying, setting out, under-excavation, arch installation, mesh and connecting bar welding (optional), and explosive charging. Remarkably, it achieves all this without needing to move, ensuring efficiency and precision. Designed with an engineering chassis, it boasts a dual power system (diesel and electric), short wheelbase, compact form, and exceptional maneuverability, making it ideal for complex tunnel conditions. The boom, operated via wireless remote or manual control, enhances safety and operational ease. The LG312K stands out for its speed, efficiency, and energy-saving capabilities.
Expandable Man Basket Our cutting-edge equipment incorporates an expandable man basket, providing ample operating space to accommodate 3-6 personnel. This feature proves invaluable for tasks such as explosive loading and anchor rod placement, ensuring both efficiency and safety.
High Efficiency With an advanced three-arm structure and three grippers and hanging baskets, the LG312K supports full-section, two-step, and three-step construction methods. This innovative design allows for the vertical frame's entire construction process to be completed in approximately one hour, significantly enhancing productivity.
Installation of Precast Arch Our patented multi-frame precast arch technology (Patent No. ZL202022537953.5) minimizes the risks and duration of working in hazardous areas. This breakthrough technology significantly boosts construction efficiency and safety, setting new industry standards.
Reduction of Number of Operators In stark contrast to traditional methods requiring eight or more operators, the LG312K allows the entire construction operation to be efficiently managed by just 3-4 people, reducing manpower and operational costs.
Auxiliary Function Integration Equipped with a breaking hammer, the LG312K seamlessly transitions to under-excavation operations post-arch installation, showcasing its multifunctional prowess.
Small Overall Dimensions Engineered with a lightweight and compact design, the LG312K is perfectly suited for small-section construction conditions, offering unparalleled versatility and ease of operation.
Equipment Informatization (Optional) The LG312K supports a variety of 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. These features enable comprehensive oversight and control, greatly enhancing operational efficiency and safety.
