The LG312K The intelligent arch integrated trolley, LG312K, seamlessly combines a suite of advanced processes such as surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging. It executes a complete tunnel excavation and arch installation in one go without relocation. Engineered with a versatile chassis and a dual power diesel-electric system, it boasts a short wheelbase, compact design, exceptional maneuverability, and robust traction, making it ideal for challenging tunnel conditions. The boom features both wireless remote control and manual operation, ensuring precise and safe movements, thus promising speed, efficiency, and energy conservation.
Expandable Man Basket: This equipment includes a spacious, expandable man basket, accommodating up to 3-6 personnel. It is perfectly designed for tasks such as loading explosives and positioning anchor rods, enhancing operational efficiency and safety.
High Efficiency: Featuring a sophisticated three-arm structure, the LG312K is equipped with three grippers and three hanging baskets, adaptable to full sections, two-step, and three-step construction methods. This allows the completion of all vertical frame construction processes in approximately one hour, dramatically improving productivity.
Installation of Precast Arch: Utilizing our patented multi-frame precast arch technology (patent No. ZL202022537953.5), this equipment significantly reduces the duration and risk of operations in hazardous areas, thereby enhancing overall construction efficiency.
Reduction of Number of Operators: With the LG312K, the entire construction operation can be efficiently managed by just 3-4 operators, compared to the traditional requirement of 8 or more personnel, resulting in substantial labor cost savings.
Auxiliary Function Integration: Equipped with a breaking hammer, the LG312K can promptly commence under-excavation operations post arch installation, streamlining the construction process.
Compact Overall Dimensions: The vehicle is designed with a lightweight and compact structure, perfectly suited for operations in small section construction scenarios, maintaining high performance even in restricted spaces.
Equipment Informatization (Optional): The LG312K supports a range of intelligent 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, offering a comprehensive suite of digital tools for advanced operations.
