The LG312K The intelligent arch integrated trolley, model LG312K, is a marvel of modern engineering. It seamlessly integrates multiple critical processes such as surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging. With the capability to complete a one-time excavation and arch installation of tunnels without moving, this innovative machine redefines efficiency. The entire vehicle is built on an engineering chassis with a dual power system (diesel and electric), boasting a short wheelbase, compact design, exceptional maneuverability, and impressive traction, making it ideal for complex tunnel pavements. The boom features wireless remote control and manual operation, ensuring ease of movement management. This setup guarantees safety, speed, high efficiency, and energy conservation.
Expandable Man Basket: The LG312K features an expandable man basket, offering ample operating space and accommodating 3-6 individuals. Ideal for tasks such as loading explosives and anchor rods, this feature enhances operational versatility.
High Efficiency: Utilizing a three-arm structure with three grippers and three hanging baskets, the LG312K supports full-section, two-step, and three-step construction methods. Remarkably, all vertical frame construction processes can be completed in approximately one hour, exemplifying its high efficiency.
Installation of Precast Arch: Our proprietary multi-frame precast arch technology (patent No. ZL202022537953.5) significantly reduces the working duration and construction risks associated with dangerous working faces. This advancement not only enhances safety but also dramatically boosts construction efficiency.
Reduction of Number of Operators: Remarkably, the entire construction operation with the LG312K can be efficiently managed by just 3-4 operators, as opposed to the traditional requirement of 8 or more personnel, streamlining workforce needs.
Auxiliary Function Integration: Equipped with a breaking hammer, the LG312K enables under-excavation operations immediately after arch installation, integrating auxiliary functions seamlessly for uninterrupted workflow.
Small Overall Dimensions: With a lightweight design and compact overall dimensions, the LG312K is specifically engineered for small section construction conditions, ensuring adaptability and ease of use in limited spaces.
Equipment Informatization (Optional): Optional advanced informatization features include cluster management, positioning, video monitoring, interphone functionality, pre-alarm systems, data management, integration with tunnel BIM technology and digital twin, construction report management, tunnel contour scanning, remote control, and more.
