The LG312K The intelligent arch integrated trolley, LG312K, revolutionizes the tunnel excavation and arch installation process. Capable of seamlessly integrating surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging, this sophisticated machine ensures that the entire process is completed without the need to move the equipment. The vehicle is designed with an engineering chassis and a dual power system (diesel and electric) that boasts a short wheelbase and compact structure, delivering flexible maneuverability and exceptional traction. This makes it ideal for a variety of complex tunnel pavement conditions. Additionally, the boom can be operated via wireless remote control or manual control, providing ease of operation and ensuring safety, speed, high efficiency, and energy savings.
Expandable Man Basket: The equipment comes with an expandable man basket that offers a spacious operating area, accommodating 3-6 people. This feature is particularly useful for loading explosives and anchor rods, enhancing operational efficiency.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, this equipment is versatile enough to handle full sections, two-step, and three-step construction methods. Impressively, all vertical frame construction processes can be completed in approximately one hour, maximizing productivity.
Installation of Precast Arch: Our proprietary multi-frame precast arch technology (patent No. ZL202022537953.5) significantly reduces working duration and construction risks associated with dangerous work faces. This innovation leads to a substantial increase in construction efficiency.
Reduction of Number of Operators: Remarkably, the entire construction operation can be completed by just 3-4 people, a significant reduction from the traditional requirement of 8 or more operators. This translates to lower labor costs and streamlined operations.
Auxiliary Function Integration: Equipped with a breaking hammer, the machine allows for under-excavation operations to be conducted immediately after arch installation, ensuring continuity and efficiency in the construction process.
Small Overall Dimensions: Designed with a lightweight and compact structure, this vehicle is perfectly suited for small section construction conditions, enabling it to navigate through constrained environments with ease.
Equipment Informatization (Optional): The LG312K supports advanced informatization features including cluster management, positioning function, video monitoring, interphone function, pre-alarm function, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control. These features enhance operational oversight and efficiency.
