The LG312K The LG312K is an intelligent arch-integrated trolley that masterfully integrates multiple processes such as surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging. This advanced equipment can complete one-time excavation and arch installation within a tunnel without the need for machine relocation. Boasting an engineering chassis with a dual power system (diesel and electric), it features a short wheelbase, compact body, and flexible maneuverability, making it ideal for various complex tunnel pavement conditions. The boom operation is facilitated via wireless remote control and manual control, ensuring easy and safe operation. This setup guarantees rapid, efficient, and energy-saving performance.
Expandable Man Basket: Our equipment comes with an expandable man basket, providing a larger operating space capable of accommodating 3-6 people. It is perfectly suited for loading explosives and anchor rods, enhancing operational safety and efficiency.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, the LG312K is designed to accommodate full sections, as well as two-step and three-step construction methods. Remarkably, all construction processes related to the vertical frame can be completed in about one hour.
Installation of Precast Arch: Utilizing our company's patented multi-frame precast arch technology (Patent No. ZL202022537953.5), the LG312K significantly reduces the working duration and construction risk associated with dangerous working faces. This innovation dramatically enhances construction efficiency.
Reduction of Number of Operators: The entire construction operation can be efficiently completed by just 3-4 people, compared to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: Equipped with a breaking hammer, the LG312K allows for seamless under-excavation operations immediately after arch installation.
Small Overall Dimensions: The LG312K features a lightweight and compact design, making it suitable for small-section construction conditions. Its reduced dimensions enhance maneuverability in confined spaces.
Equipment Informatization (Optional): Supporting a suite of advanced functionalities, the LG312K offers cluster management, positioning, video monitoring, interphone function, pre-alarm function, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, and remote control.
