250m GL-IIA Trailer Type Water Well Drilling Machine (GL-IIA)

250m Trailer Type Water Well Drill Rig Our trailer mounted type water well drilling rig are widely used for borehole drilling domestic and world wide. They can work with air compessor and DTH hammer and bits to realize the high efficiency air drilling, also can work with mud pump and tricone bits for the mud drilling. If the working layer is with some rock, it can do the core drilling to get the rocks out and continue the drilling work. Overall speaking, it is a functional drill.The drilling depth of our GL-IIA trailer type water well drill rig is 250m and drilling diameter 90-1200mm. The big range of drilling diameter can fully meet customer's different drilling needs.The structure of our GL-IIA is simple, which is easy to operate and maintain. We can also send our working staff aborad for the training to our customers. For any technical questions, we could solve quickly.  Main ApplicationDrilling wells for urban and rural lifeDrilling wells for agricultural irrigation and industriesDrilling for geotechnical surveyDrilling construction engineering holesDrilling geothermal pump wells  Working Pictures1.
