Since the launch of the new upgraded "lightweight" LG312M intelligent arch frame integrated trolley by LanHi Installation, it has received widespread acclaim and has been continuously used in tunnel construction projects across the country.

　　This intelligent arch frame integrated trolley integrates multiple processes, including measurement, excavation, arch frame installation, welding of mesh and connecting bars, etc., with features of fast, efficient, energy-saving, and safe operation. It has been upgraded in appearance, weight, and boom, bringing a brand-new flexible experience to tunnel construction.

　　The new generation of LG312M intelligent arch frame trolley has the following features:

　　1. Lightweight design: 20% reduction in weight, smaller dimensions, making construction more flexible, capable of completing the excavation and arch frame installation of double-line tunnels without relocating the machine.

　　2. High-level boom: Utilizing a design of three arms, three grippers, and three baskets, making construction more convenient, effectively reducing construction time, and improving construction efficiency.

　　3. Extendable baskets: Increasing operating space for baskets, facilitating the loading of explosives and anchor rods, enhancing construction safety.

　　This trolley not only saves time and effort but also has high safety, able to adapt to various complex tunnel conditions, serving as an intelligent and efficient construction tool. In practical applications, it has been successfully used in multiple engineering projects such as Chengnan Expressway Expansion, Hydropower VII Bureau Bara Hydropower Station, Plateau Railway, and Jiuma Expressway, providing customers with fast, accurate, and flexible mechanized arching services.

　　In the future, Blue Sea Smart Installation will continue to adhere to the goal of replacing manpower with machines and intelligent construction, continuously advancing the intelligent upgrading of products, helping to continuously improve the quality of tunnel engineering, and creating greater value for customers.
