  • KQD70
  • KQD100

Our KQD70/KQD100 electric DTH drilling rig is driven by an energy-saving and eco-friendly electromotor. A cycloidal pin wheel speed reducer is used in this DTH driller. This kind of reducer can provide the electric drilling machine with big rotating torque and high rock drilling efficiency. An efficient overload protection circuit is designed to make the electric DTH drilling rig stable and reliable.
