,400m air drilling rig
The Hydraulic 400m Drilling Depth Air DTH Drilling Rig is engineered to deliver consistent, high-speed drilling capability across diverse geological conditions. Its advanced hydraulic architecture provides smooth operation while the high-capacity air system ensures deep penetration in hard rock formations. Contractors value its fast setup time and minimal maintenance requirements.
The ST400 Air DTH Drilling Rig can perform drilling jobs in different strata, with borehole diameters up to 130-400mm. The rig utilizes hydraulic technology, supporting high torque hydraulic motor rotation and large bore hydraulic cylinder push. The multi-cylinder engine from renowned manufacturers powers the hydraulic system, while two-stage air filter and air compressor intake design prolong the service life of the diesel engine.
Special pump set design facilitates maintenance and reduces maintenance costs. Centralized control of the hydraulic control table ensures convenient operation.
