The AT-1500 frame articulated raise boring rig is a shaft construction equipment optimized for your narrow tunnels and complex turning needs. Its core feature is the articulated chassis design, which improves underground mobility and terrain adaptability through flexible connections. It is especially suitable for mines or tunnel projects with many bends and frequent slope changes.
AT-1500 Frame articulated raise boring rig adopts multi-joint articulated chassis design. The front and rear frames are connected by hydraulic articulated shafts and can swing independently to adapt to the undulating and inclined road surface underground, reducing your leveling time. In addition, it also adopts a compact design. The length of the whole machine is 30% shorter than that of the traditional wheel-rail type, which is suitable for narrow lanes with a width of ≥3 meters.
The frame-articulated AT-1500 hydraulic steering system supports crab mode (diagonal movement), avoiding obstacles or working close to the side, and can continuously construct in multi-curved lanes.
Our AT-1500 raise boring machine adopts high torque and high thrust design, which significantly improves the drilling speed under hard rock conditions and can effectively shorten your construction period. In addition, the use of automatic rod changing technology reduces manual intervention and has strong continuous operation capability, which can greatly save your construction costs.
The front and rear frames are connected by hydraulic articulated shafts and can swing independently by ±15° to adapt to the slope, undulations or local collapse areas of the tunnel, reducing the leveling time.
During drilling, inject quick-setting slurry or install recyclable wall protection pipes simultaneously; reduce the propulsion speed (<0.5 m/h) to reduce disturbance to the surrounding rock.
