The LG312K The intelligent arch integrated trolley LG312K is an innovative powerhouse that combines surveying, under-excavation operations, arch installations, mesh and connecting bar welding (optional), explosive charging, and more. This marvel can accomplish comprehensive tunnel excavation and arch installation in one seamless operation, eliminating the need to reposition the machine. Built on a robust engineering chassis, it boasts a dual power system—diesel and electric—paired with a short wheelbase and compact design for unmatched flexibility and traction. These features make it an ideal choice for navigating complex tunnel pavement conditions. The boom is operated via wireless remote control in conjunction with manual control, ensuring precise, safe, and efficient maneuverability, all while maximizing energy savings.
Expandable Man Basket: Our equipment comes with an expandable man basket, offering a generous workspace that accommodates 3-6 operators. This expanded capacity is perfect for tasks such as loading explosives and anchor rods, enhancing operational efficiency and safety.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, this equipment supports various construction methods, including full sections, two steps, and three steps. The vertical frame construction processes can be completed in about one hour, significantly optimizing workflow.
Installation of Precast Arch: Leveraging our patented multi-frame precast arch technology (Patent No. ZL202022537953.5), this setup reduces both the working duration and the risks associated with dangerous working faces. This technology is a game-changer, boosting construction efficiency manifold.
Reduction of Number of Operators: Revolutionizing traditional processes, this equipment allows for the entire construction operation to be managed by just 3-4 people, compared to the 8 or more required by conventional methods. This represents a significant leap in resource efficiency and operational management.
Auxiliary Function Integration: Equipped with a breaking hammer, it facilitates immediate under-excavation operations post-arch installation, thereby streamlining the workflow and reducing downtimes.
Small Overall Dimensions: Designed with a focus on lightweight construction, the equipment's small overall dimensions make it perfectly suited for small section construction conditions, ensuring that no space is too constrained for efficient operation.
Equipment Informatization (Optional): Our advanced informatization options include cluster management, positioning functions, video monitoring, interphone functions, pre-alarm systems, data management, tunnel BIM technology, digital twin capabilities, construction report management, tunnel contour scanning, and remote control functionalities. These features offer comprehensive management and monitoring for enhanced operational control.
