8-9 ton Hirail Tunnel Excavator

The JG80LT 8-ton Four-Arm Excavator redefines efficiency in confined-space excavation. Engineered specifically for tunnel construction and underground projects, its compact crawler chassis ensures agile mobility in low-clearance environments. The revolutionary four-arm design enables simultaneous multi-task operations—such as digging, lifting, and grading—without repositioning, drastically reducing downtime. With robust 8-ton capacity and optimized hydraulic power, it delivers exceptional digging force and stability on challenging terrains, making it indispensable for metro systems, mining, and subterranean infrastructure development. 

The JG80LT tunnel excavator is specially designed for railway tunnel construction. With its innovative four-arm structure and shell hopper design, it can easily control the narrow and complex working environment. The four-arm system gives the equipment excellent flexibility, which can be extended and rotated from multiple angles to accurately avoid obstacles in the tunnel; With its unique arc structure, the shell hopper can efficiently grasp and transfer all kinds of muck and gravel, greatly reduce material scattering and improve the efficiency of continuous operation.
