The descriptions of the hydraulic crawler water well borehole drill rig machine.
The hydraulic crawler water well borehole drill rig machine is a type of hydraulic water well drill rig that can drill 200m depth into the earth, the max. water well borehole drilling diameter is 140-254mm. The hydraulic rotary head will produce big torque while drilling a water well borehole, which will help to drill a deep water well borehole. The suitable drilling pipe for this hydraulic crawler water well borehole drill rig machine is Φ76mm and Φ89mm. The two crawler tracks of this water well borehole drill rig machine are rubber type, and it can walk on the city road without damaging the road.

The features of the hydraulic crawler water well borehole drill rig machine.
- The hydraulic crawler water well borehole drill rig machine uses a hydraulic system to drill, so the drilling torque is bigger.
- The chassis of the water well borehole drill rig machine is excavator chassis, which is strong and powerful to walk on the road.
- The diesel engine of this water well borehole drill rig machine is a 65 kW Yuchai diesel engine.
- The hydraulic crawler water well borehole drill rig machine adopts the screw air compressor drilling method and the mud pump drilling method. This depends on the geological conditions.
