Product Description

Product Description

The LGM312U Introducing the intelligent integrated arch anchor trolley, the LGM312U, featuring a robust engineering chassis and a versatile single anchor system. With its advanced four-wheel steering, four-wheel drive, and bi-directional driving capabilities, this machine is built for excellence. The dual diesel-electric power system ensures seamless electric construction operations and reliable diesel-powered backup for emergencies. Equipped with a three-arm remote control, it excels in precise arch frame installation, various benching methods, and under-excavation and welding during installation. Experience unparalleled flexibility and efficiency in tunnel operations.

Functional Integration: The intelligent integrated arch anchor trolley merges multiple processes into a single, powerful unit. It performs measuring and placing points, under-excavation operations, arch frame installation, advanced support, system anchor construction, optional anchor grouting, anchor net installation, and more with ease.

Equipment Digitization (Optional): Unlock advanced features like cluster management, precise positioning, video surveillance, walkie-talkie communications, pre/alarm functions, comprehensive data management, tunnel BIM technology, and digital twin capabilities. Enhance your operations with remote control, tunnel contour scanning, and detailed construction reports.
management, tunnel contour scanning, remote control and other functions.

High Efficiency: Featuring a three-arm, three-gripper, and dual-basket structure, with a maximum lifting force of 2 tons in the middle arm, the LGM312U completes the entire construction process in approximately one hour, ensuring maximum productivity.

Installation of Prefabricated Arch Frames: Utilizing our patented multi-frame prefabricated segmented assembly and folding techniques, we manufacture the arch frames outside the tunnel. This significantly reduces exposure to hazardous surface conditions, enhances safety, and boosts overall construction efficiency.
tunnel. This reduces the required working time on dangerous surfaces and construction safety risks, and greatly improves overall efficiency.

Single Anchor System: Achieve maximum drilling depths of up to 4.5 meters. The middle arm frames are designed for feet locking, system anchoring, and advanced anchoring operations, providing comprehensive support.

Expandable Hanging Basket: Our trolley features an expandable hanging basket, offering a generous operating space ideal for installing explosives and anchor rods.

Optional Grouting Function: The LGM312U can be equipped with an optional grouting system, enabling swift grouting operations immediately after anchor installation.

Less Operating Personnel: Revolutionizing construction efficiency, our system requires only 3-4 operators, compared to the traditional 8 or more, significantly reducing labor costs.

Auxiliary Function Integration: Equipped with a breaker hammer and welding machine, the LGM312U performs under-excavation processing and welding operations seamlessly during arch installation.
