Small DTH drilling rig is used in the construction industry to produce piles into rock, also water wells in some small diameter with not deep hole, and drilling bores for geothermal ground source heat pumps. Oil & Gas- Deepwell Bore Holes : Air hammers can be used as long as cutting uplift and borehole stability are ensured.

1. The rock driling rig uses a motor as the turning power through a high-performance reducer; the cylinder uses the propulsion power. The hydraulic system is omitted, so the mechanical efficiency is high, the cost is low, and the performance is stable.
2, with anti-card protection, when the drilling tool is stuck, the motor is not easy to burn, the reducer is not easy to damage. 3. Light and easy to move, the weight of the DTH rig is less than 500Kg, and it can be decomposed into three pieces.
4. The rolling carriage is adopted, and the track is not easy to wear.
5. The down-the-hole drilling rig adopts semi-automatic dismantling drill pipe, with high working efficiency
