Uses
We've been building drilling rigs for over a decade. Here's what makes this compact hydraulic DTH rig stand out:
Strong rotary power – Dual-motor rotary head with adjustable multi-way valve. Rotary torque up to 1,950 N·m. Works with φ76 drill pipes and φ130 holes.
Fast in soft rock – Max rotation speed 150 rpm, good for high-speed drilling in soft layers.
Light and modular – Body weight 2–4 tons. Hydraulic valve-controlled movement. Mountain and forest relocation is 60% faster.
Compact layout – Power head, hoist, and filter integrated. Simple to operate.
Deep drilling capacity – 100 meters in loose layers, up to 300 meters in hard rock.
Engine – 78 kW Yuchai (China). Reliable and easy to get parts.
Climbs well – 30° slope angle. Track ground pressure <0.08 MPa. No surface damage on wet or steep slopes.
Built for tight spaces – Works in tunnels, jungles, and narrow sites.
Mass production – Tests completed. Ready to ship.
Key advantages you'll notice:
High mechanical efficiency – Gets the job done fast.
Rod protection – Reducer stays safe when rod gets stuck.
Light and easy to move – Most units split rig and air compressor for transport.
Durable tracks – Less wear, longer life.
Semi-automatic rod removal – Saves time and manual work.
