The DRW200 Water Well Drilling Rig features hydraulic rotation and feed, a crawler chassis, a drilling depth of 200 m and a hole diameter range of 140–254 mm.
The DRW200 Water Well Drilling Rig is a crawler-mounted machine with a drilling depth of 200 m and a hole diameter range of 140–254 mm. Machine weight is 5 t.
The rig uses hydraulic rotation and feed and works with 76 mm and 89 mm drill pipe.
DRW200 Water Well Drilling Rig: drilling and air supply
How do drilling depth and feed stroke differ?
Drilling depth is 200 m. The 3.3 m feed stroke is the distance the rotary head travels along the mast in one feed movement. Drill pipe lengths are 1.5, 2.0 and 3.0 m.
Which air-supply specifications matter?
The operating air-pressure range is 1.7–2.5 MPa and air consumption is 17–31 m³/min. Use both pressure and flow when selecting the air compressor.
Hydraulic rotation and feed
Hydraulic motors drive the mast-mounted rotary head. Rotary torque is 3,400–4,700 N·m and rotary speed is 45–70 rpm. The hydraulic feed system moves the drill string along a 3.3 m stroke.
Centralized control panel
Manual operating levers and gauges are grouped on a side-mounted console beside the mast.
Folding mast and crawler chassis
The mast folds horizontally along the chassis for transport and stands upright for drilling. Crawler tracks move the rig between drilling positions. Four corner outriggers support the chassis, with an outrigger stroke of 1.4 m.
