The LG312K The Intelligent Arch Integrated Trolley (LG312K) revolutionizes tunnel construction by seamlessly integrating multiple processes including surveying, setting out, under-excavation operation, arch installation, mesh and connecting bar welding (optional), and explosive charging. Achieve a complete one-time excavation and arch installation without having to relocate the machine. The chassis is engineered for optimal performance with a diesel and electric dual power system, ensuring short wheelbase, compact design, superb maneuverability, and exceptional traction. This adaptability makes it ideal for various complex tunnel conditions. The boom, controlled via wireless remote and manual operations, allows for precise movements, enhancing safety, speed, efficiency, and energy conservation.
Expandable Man Basket: The equipment is equipped with an expandable man basket, providing a spacious operating environment that can accommodate 3-6 people. This feature is essential for the efficient loading of explosives and anchor rods.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, the LG312K supports a variety of construction methods including full sections, two steps, and three steps. The vertical frame construction processes are completed in roughly one hour, significantly enhancing operational efficiency.
Installation of Precast Arch: Utilizing our proprietary multi-frame precast arch technology (Patent No. ZL202022537953.5), the LG312K reduces both the duration and risk associated with dangerous work faces. This innovation markedly improves overall construction efficiency.
Reduction of Number of Operators: Remarkably, the entire construction operation can be executed by just 3-4 individuals, in contrast to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: Outfitted with a breaking hammer, the LG312K allows for under-excavation operations immediately following arch installation, streamlining the construction process.
Small Overall Dimensions: Designed with a lightweight and compact structure, the LG312K is perfectly suited for small section construction conditions, offering unparalleled adaptability.
Equipment Informatization (Optional): The LG312K supports advanced informatization features including cluster management, positioning functionality, video monitoring, interphone function, pre-alarm systems, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control operations.
