SP450(450M) Water Well Drilling Rig

SP450 water well drilling rig is widely applied in the hole drilling of water wells, geothermal wells and so on. It can operate under different complicated geological conditions, featuring with a larger drilling diameter. The unique longhole axial compression control system helps to adjust the propulsion reasonably, which reduces the steering resistance during the deep well drilling. By adopting the two-stage telescopic carriage, the drill pipe adopted can be 6m, greatly reducing the times of pipe extension. Besides, the overhead drive head comes with a large spindle diameter, making the drilling rig suitable for the drilling of mud, air and foam to satisfy the requirements of different geological conditions.

Key Parameters
Drilling Depth:450m
Drilling Diameter:140-350mm
Diesel Engine Power:103Kw


1. The water well drilling rig equips a 103 kW Wechai turbocharged engine to provide powerful movement.
2. Patented composite arm comes with a long stroke and the dual cylinder lifting device provides a large lifting power of 13T.
3. The main arm of this water well drilling rig is installed with a stopper to protect the cylinder.
4. Professional and durable base offers a strong bearing capacity and its wide chain plate causes small damage to the road.
5. The design of parallel transmission with independent oil pump allows for sufficient power, reasonable distribution. The unique hydraulic system offers simple maintenance and low cost.
6. The hydraulic motor is equipped with a reducer to ensure durability and long service life.
7. Fast distribution valve allows for three-gear speed regulation and a rotary speed of 50-135 rpm, enabling the drilling of water and air.
8. Each hydraulic hose is covered with a soft management unit to enlarge its service life.
9. SP450 water well drilling rig is driven by a diesel engine and its walking, turning, propelling, lifting, leg and discharge rod are hydraulic controlled.
10. This crawler mounted geothermal drilling rig is convenient to move. Its rubber tracked base allows it to travel freely in the city and courtyards without damaging the ground.
11. Strong hydraulic leg enables the quick adjustment of the rig height stably for easy and transposition.
12. The water well drilling rig’s special wellhead provides a certain center for drilling, ensuring a vertical drilling and the position accuracy.
13. The mechanical positioning of the carriage and frame improves the stability of this water well drilling rig.
14. The pneumatic system adopts a customized lubricator to lubricate the drill hammer, which greatly prolongs it service life.
