KW30 Multi-function Geothermal Water Well Drilling Rig (Truck Mounted Type Optional)
Our KW30 water well drilling rig can be used for drilling various holes like water wells, holes for ground source heat pumps, and so on. It can drill big-diameter and deep holes (Max. depth = 300m) in various types of stratums. The special design has given rise to a variety of features, some of which have been detailed below. If you need more information, feel free to contact us.
Feature
1. High torque rotating mechanism
As a professional drill rig provider, we have adopted a hydraulic motor driven straight tooth gear reducer from a famous company for the water well drilling rig. This deep well drilling machine has a compact structure and features with reliable drilling performance.
2. Combined type positioning device
The combined type positioning device in this water well drilling rig can adjust the positioning plate according to the types of drill rod and drill hammer, ensuring the high precision of the drilling process.
3. Flexible supporting legs
The swinging type foreleg and stretchable back legs can stably support the machine. During the transportation, all the legs could be retracted back so that less space is needed.
4. Deep hole axle load regulating system
Our special deep hole axle load regulating system of our water well drilling rig can adjust the propulsion force as needed to reduce the resistance to the rotating mechanism when drilling deep holes. Thus the drilling efficiency can be enhanced.
5. Double-stage telescopic carriage
A double-stage telescopic carriage is used, so that you can use the 4.5m drill rod without increasing the carriage's length. Thus the rod connecting times can be reduced and the working efficiency can be enhanced.
