The LG312K Our intelligent arch integrated trolley, the LG312K, merges a multitude of processes such as surveying, setting out, under-excavation operations, arch installation, mesh and connecting bar welding (optional), and explosive charging. This exceptional machine achieves one-time excavation and arch installation of tunnels without necessitating relocation. It boasts an engineering chassis, a dual power system (diesel and electric), a short wheelbase, a compact body, and superior maneuverability with outstanding traction. This makes the LG312K ideal for a variety of complex tunnel paving conditions. The boom can be effortlessly managed through wireless remote control and manual operation, ensuring maximum safety, efficiency, speed, and energy savings.
Expandable Man Basket: Featuring a versatile expandable man basket, this equipment offers a spacious operating area accommodating 3-6 people. It is particularly well-suited for loading explosives and anchor rods.
High Efficiency: With its innovative three-arm structure, three grippers, and three hanging baskets, this system supports full sections, two-step, and three-step construction methods. The entire vertical frame construction can be accomplished in around an hour, greatly enhancing productivity.
Installation of Precast Arch: Leveraging our patented technology for multi-frame precast arch (Patent No. ZL202022537953.5), this equipment significantly reduces working duration and mitigates construction risks at hazardous working faces, thereby vastly improving construction efficiency.
Reduction in Number of Operators: This advanced system ensures that the entire construction operation can be efficiently handled by just 3-4 people, compared to the traditional method that requires 8 or more operators.
Auxiliary Function Integration: The equipment comes with an integrated breaking hammer, allowing for under-excavation operations immediately after the arch installation.
Compact Dimensions: Designed with a lightweight structure and compact dimensions, this vehicle is perfect for construction projects in small sections.
Equipment Informatization (Optional): Our system supports a plethora of advanced functionalities including cluster management, positioning, video monitoring, interphone communication, pre-alarm signals, data management, tunnel BIM technology, digital twin, construction reporting, tunnel contour scanning, remote control, and more.
