JG80LT 8-ton four-arm excavator crawler tunnel excavator

The four-arm design of the tunnel excavator provides an unprecedented degree of joint freedom, enabling easy steering and precise positioning in narrow and tortuous tunnel environments. Optimized for tunneling, this excavator works efficiently in low, crowded Spaces, and its compact structure and four-arm configuration ensure stability in rock or soil layers. By optimizing the arm trajectory and power system, the four-arm excavator significantly improves the consistency of excavation, loading and cleaning, reducing repetitive movements and time waste.

Product Overview 

JG80LT 8 tons four arm shell bucket tunnel excavator

Tailored for extreme conditions, the JG80LT integrates four independently controlled hydraulic arms for unprecedented flexibility around obstacles. Reinforced crawler chassis minimizes ground pressure while providing traction on loose or uneven surfaces. Its modular construction allows for quick switching of accessories (e.g. breakers, auger drills) to solve a variety of tasks - from precision rock removal to pipe installation - all within a narrow 1.8-meter-wide profile. Enhanced safety features, including advanced dust filtration and low-emission engines, ensure operator protection and compliance in closed workplaces, cementing its role as the ultimate underground engineering partner.
