Double arm rock drilling rig QLZY213AG
Scope of Application
Suitable for 36m 2-176m2 Excavation drilling and anchor bolt hole operations for highway and railway tunnels, pumped-storage power stations, hydropower stations, and underground caverns.
Product Features
High efficiency and energy saving
The single-hole drilling speed is 5–6 times that of manual pneumatic drills, significantly boosting drilling efficiency.
The construction method is highly adaptable
Articulated boom design; the boom can operate below the horizontal plane, enabling work on two‑step, three‑step, and upper, middle, and lower levels.
Strong cross-sectional adaptability
The articulated boom structure offers a wide working envelope, accommodates construction across multiple tunnel cross-section types, and enables invert excavation, thereby overcoming the limitations of conventional rock‑drilling rigs that cannot perform invert‑lining operations.
Easy to operate
Equipped with computer control, the pipe rack enables self-balancing operation and displays the angle of the advancing beam, effectively controlling the excavation profile and minimizing over‑ or under‑excavation.
High personnel adaptability
Remote operation is simple and easy to learn, allowing close‑range observation of the drilling process and effective control of over‑ or under‑excavation. The machine has a short overall length, offering excellent maneuverability and ease of operation.
