2.Fully hydraulic operation. The drilling speed, torque, propulsion axial pressure, counter-axial pressure, propulsion speed and lifting speed of the drilling rig can be adjusted at any time to meet the needs of different drilling tool operating conditions and different construction techniques.
3.Top drive rotary propulsion lift. It is convenient for connecting and unloading the drill pipe, shortens the auxiliary time, and is also conducive to drilling with the pipe.
