Product Features
Our company's drilling rig series boasts stable performance and excellent quality.
High Rock Penetration Efficiency
Utilizes advanced pneumatic DTH hammers providing massive single-impact energy, resulting in significantly faster drilling speeds in hard rock compared to traditional rotary rigs, effectively shortening project timelines.
Superior Hard-Rock Adaptability
Specially calibrated to conquer tough strata with Protodyakonov hardness ratings from f = 6 up to f = 20, effortlessly processing granite, limestone, basalt, and quartz veins.
Powerful Hydraulic System & Massive Torque
Driven by high-power diesel systems delivering up to 8000 N·m of output spindle torque, ensuring smooth anti-jamming pipe extraction and heavy advance operations
Heavy-Duty Crawler Mobility
Features an all-terrain steel or rubber track chassis with high ground clearance (380mm) and a 30° gradeability angle, enabling flexible walking and structural self-anchoring on rugged, unpaved jobsites.
Specialized Solar Piling Adaptability
The high torque and robust ground clearance layout make it highly adaptive for modern renewable energy projects, allowing fast and precise ground-mount solar rack piling installations.
Eco-Friendly & Low Air Consumption
Optimized pneumatic routing allows wide volumetric flexibility (15–50 m³/min) to match diverse air compressors, maximizing energy efficiency while minimizing onsite carbon emissions.
