RC drill rigs for drilling depths up to 1000m with 105-800mm hole diameters
The reverse circulation drilling rig offers a maximum drilling depth of 1000 m and is suitable for a wide range of formations from F4 to F22.
It can be equipped with a high-power engine and an high-torque power head (24,000 N•m).
The rig features a hydraulically driven crawler chassis, a reverse-circulation DTH hammer, and powerful feed and lifting capacities.
It supports deep-hole and long-distance drilling in hard rock formations, ensuring stable, durable performance and easy maintenance.
Ideal for engineering exploration and large-scale mining operations.
