Reverse Circulation Drilling Machine
As a global leader in RC Drilling Machine manufacturing, we offer the most competitive solutions for hydraulic large bore piling construction. With diameters of up to 7.5m, LPR Global’s Reverse Circulation Drilling Machine is best suited for large bore vertical excavation in all soil conditions.
Our Reverse Circulation Drilling machine was developed with low noise and vibration for heavy civil construction in urban or sensitive environments. Therefore, it is suitable for inshore construction of urban high-rise buildings and underground subways, as well as marine construction of bridges and wind tower installations. Furthermore, the RC drilling machine is designed for minimal overflow of the cuttings for efficient, clean site maintenance.
Powered by our hydraulic power pack, our RC drilling machine has a Power Swivel Torque of 160 kNm up to 1,200 kNm. Moreover, our Reverse Circulation Drilling Machine goes beyond the market standard with with a patented drill bit and normalized heat treatment for improved strength.
