KW400 water well drilling rig is mainly used in the 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. The use of the two-stage telescopic carriage allows a drill pipe to 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.

Features
1. The water well drilling rig equips a 96 kW Yuchai turbocharged engine to provide powerful movement.
2. Patented composite arm provides a long stroke and the dual cylinder lifting device provides a large lifting power.
3. The main arm of this water well drilling rig is installed with a stopper to protect the cylinder.
4. The professional base is durable and it offers 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 66-135 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. KW400 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 is convenient to move. Its rubber track chassis allows it to travel freely in the city and courtyards without damaging the ground.
11. Strong hydraulic leg can adjust the height of the rig quickly and stably for easy loading 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 comes with a customized lubricator to lubricate hammer, greatly extending its service life.
