Another 10 units in the niche market! Batch delivery of Liugong's National IV 922FTN tunnel boring machines

The tunnel passes through the mountains, turning the natural barrier into a thoroughfare

China has a vast land area with rugged terrain. Mountains, plateaus and hills alone account for about 67% of its land area, and there are also interspersed rivers, seas, mountains and other landforms. The mountains are vast and boundless, with peaks and ridges overlapping. How many families who rely on the mountains but cannot make a living have their dreams of life blocked by the vast mountains because of the difficulty in traveling. In ancient times, there was the story of Yu Gong moving mountains. Nowadays, the passage of tunnels has finally turned the natural barrier into a thoroughfare. At present, China has become the country with the most and fastest-growing highway tunnels in the world.

The 922FTN dispatched today is a brand-new tunnel-specific excavator for the fourth stage of national standards, following the popular Liugong 921ETN and 923ETN in tunnel construction units. It integrates the best of tunnel construction experience and the F series platform.

922FTN Tunnel Expert

The 922FTN is a tunnel-specific excavator specially launched in light of the particularities of tunnel construction, such as a large amount of stone, high strength, diverse construction methods, environmental hazards, and narrow working areas. The whole machine adopts a fully electrically controlled hydraulic system, with comprehensive reinforcement and protection design, etc., to meet the working environment and requirements of small space, high dust, high intensity and high risk in tunnel construction.

Exclusive tunnel customization is even more powerful

The low-oxygen adaptive program can also stimulate vigorous power in the low-oxygen environment of the tunnel. Large-angle cooling fan, providing stronger heat dissipation capacity; The oil bath air filter meets the construction requirements of the high-temperature, humid and dusty environment in tunnels. Reinforced rock bucket for tunnels with hooks; The chassis has been specially optimized, featuring full-plate track beams, double-sided support drag sprockets, and welded reinforcing ribs on the guide wheel supports. The chassis is strong, solid and has a longer service life, meeting the harsh excavation conditions of tunnels.

Customized tunnels are safer

The tunnel version of the high-sealed cab is equipped with an air-suspended seat. The control force of the electric control handle is reduced by 30%, making the operation easier for the operator. Front lower protective net, top rain shield, clean and comfortable driving and riding space; Laminated glass, standard rear camera and other features ensure driving safety. The entire machine is standardly equipped with two LED lights at the front and two at the rear of the cab. The rear of the counterweight is illuminated with yellow light, allowing for a clear observation of the working distance even in the dark environment of the tunnel.

Tunnel Golden Combination

922FTN tunnel expert, with high excavation height, small turning radius and flexible maneuverability, has a natural advantage in hazard elimination at the tunnel face. It has great digging power, coordinated operation, and can freely perform tasks such as shoveling and transporting, building access roads, opening holes, and brushing door slopes. The 922FTN tunnel excavator and the 855N side-unloading loader complement each other in construction and form a golden combination for tunnel construction.
