KQY90 Pneumatic-Hydraulic DTH Drilling Rig
This product has been discontinued and removed from our shelves.
The KQY90 pneumatic-hydraulic DTH drilling rig is the first one of its kind in China. We have used a high rotating torque hydraulic motor, so the drill rod is not easy to be stuck. The innovative hydraulic system design we used makes the pneumatic-hydraulic drill rig light and energy efficient, while the unique rig locking mechanism make the drilling angle accurate and consistent. To enhance the working stability and reliability, we adopted the Chic counterweight device for this borehole driller. The centralized control system of this pneumatic-hydraulic DTH drilling rig is easy to operate.
