The LG312K The innovative arch integrated trolley seamlessly integrates a multitude of processes including surveying, setting out, under-excavation operation, arch installation, mesh installation, and connecting bar welding (optional), as well as explosive charging. This state-of-the-art machine completes a one-time tunnel excavation and arch installation without the need for repositioning. Built on an engineering chassis, it features a dual power system (diesel and electric), offering a short wheelbase, compact body, and exceptional maneuverability, making it ideal for various challenging tunnel conditions. The boom is operated via wireless remote control plus manual control, ensuring the utmost in safety, speed, efficiency, and energy conservation.
Expandable Man Basket: Our equipment comes with an expandable man basket, offering a spacious operating area that can accommodate 3 to 6 individuals. It's perfectly suited for tasks involving the loading of explosives and anchoring rods.
High Efficiency: Featuring a three-arm structure with three grippers and three hanging baskets, this equipment is versatile for full-section, two-step, and three-step construction methods. Remarkably, all vertical frame construction processes can be accomplished in roughly one hour.
Installation of Precast Arch: Utilizing our patented multi-frame precast arch technology (patent No. ZL202022537953.5), this equipment significantly reduces both the duration and risk associated with construction on dangerous working faces, thereby boosting overall construction efficiency.
Reduction of Number of Operators: This advanced construction operation can be efficiently managed by just 3 to 4 people, compared to the traditional requirement of 8 or more operators.
Auxiliary Function Integration: Equipped with a breaking hammer, the equipment facilitates under-excavation operations immediately following arch installation, streamlining the entire process.
Compact Overall Dimensions: Crafted with a lightweight design, the vehicle's small overall dimensions make it ideally suited for small-section construction scenarios.
Equipment Informatization (Optional): This advanced equipment supports a plethora of functionalities including cluster management, positioning, video monitoring, intercom, pre-alarm, data management, tunnel BIM technology, digital twin, construction report management, tunnel contour scanning, remote control, and many more.
