Product advantage
It is designed and developed for anchor hole construction in full-section highway tunnels, step construction in high-speed rail tunnels, small pipe hole construction, exploration drilling, and small-scale excavation. It features stable performance, versatile functions, and a compact structure. Equipped with an 18KW high-power rock drill, it can achieve a drilling speed of up to 2.2m/min. It is widely used in fields such as railways, highways, defense culverts, mines, and hydropower.
Wide construction scope
The drilling arm can rotate 360°during propulsion, and the drilling arm with translational propulsion can drill holes in all directions, no dead angle;
High security
It has excellent power system, greatly improves the construction environment, and achieves green construction;
High work efficiency
The high-strength chain, combined with a high torque hydraulic motor, provides reliable pushing and pulling support during the drilling process; Accurate drilling reduces the occurrence of leakage and deviation during construction, significantly improving the blasting effect;
Operating platform
Ensure that the operator has a good field of vision, simple and convenient hydraulic control console, allowing the operator to operate easier and improve work efficiency;
