Down The Hole Drilling Rigs

DTH Drilling Machines

Drilling rigs designed for drilling and blasting applications in quarries and open pit mining. Also for construction applications, foundation drilling and water well drilling. Able to drill vertical or inclined holes with diameter from 90 mm to 254 mm.

Main characteristics :

- Full view air-conditioned cab meeting FOPS & ROPS protection requirements providing noise reduction and shock resistance.

- High pressure 2-stage air compressors up to 25 Bar providing high productivity and low cost/m3.

- High torque rotary head for jamming free drilling in medium & hard rock formations. Two-stage dry dust collector with large filter area and automatic continuous self cleaning dust collection. The retractable dust collecting hood allows the operator to clearly observe and control collaring process.

- Heavy duty durable aluminum alloy feed beam provides excellent guidance and stability for high- precision drilling.

- Automatic DTH Tube Handling System.

- Tramming Mechanism. The combination of heavy duty track chassis and oscillation cylinders make the rigs extremely stable and maneuverable allowing navigation in most challenging work environment.

- Control System. Advanced control system allowing precise adjustments of all drilling parameters (inclination, air pressure, rotation speed, and feed rate) maximizing drilling efficiency, accuracy, and safety. PLC for auto protection and maintenance reminder.

- Low operation and maintenance cost.
