The LG312K The intelligent arch integrated trolley, LG312K, masterfully combines multiple processes including surveying, setting out, under-excavation operation, arch installation, mesh and connecting bar welding (optional), and explosive charging. This remarkable machine can complete both excavation and arch installation of a tunnel in one go without needing to move. Featuring an engineering chassis and a dual-power system (diesel and electric), the vehicle's short wheelbase and compact body ensure nimble maneuverability and outstanding traction, making it perfect for various challenging tunnel surfaces. The boom's wireless remote control plus manual operation allows easy management of its movement, enhancing safety, speed, efficiency, and energy conservation.
Expandable Man Basket: This equipment boasts an expandable man basket, providing a more spacious operating area that can hold 3-6 people. It is ideal for loading explosives and anchor rods.
High Efficiency: Utilizing a three-arm structure, three grippers, and three hanging baskets, this setup supports various construction methods including full sections, two steps, and three steps. All vertical frame construction processes can be completed in approximately one hour, demonstrating impressive efficiency.
Installation of Precast Arch: Our company's patented multi-frame precast arch technology (patent No. ZL202022537953.5) significantly reduces working time and construction risks on hazardous sites, thereby greatly improving overall construction efficiency.
Reduction of Number of Operators: This advanced system allows the entire construction operation to be efficiently handled by just 3-4 people, compared to traditional methods that require 8 or more workers.
Auxiliary Function Integration: Equipped with a breaking hammer, the machine can conduct under-excavation operations immediately after arch installation.
Small Overall Dimensions: Designed for lightweight efficiency, the vehicle's compact dimensions make it suitable for construction in small sections.
Equipment Informatization (Optional): This advanced system supports comprehensive functionalities such as cluster management, positioning, video monitoring, interphone, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control.
