RC drill rigs for drilling depths up to 600m with 105-550mm hole diameters
The reverse circulation drilling rig supports a maximum drilling depth of 600 m and can operate in F4-F22 formations.
It is equipped with a 179 kW engine and a high-torque power head (18,000 N•m).
The rig features hydraulically driven crawler travel, powerful feed and lifting capabilities, and supports high-pressure, high-volume DTH reverse circulation cuttings removal.
It is suitable for deep-hole drilling and hard rock formations, providing stable operation with easy maintenance.
