Cheapest Mine Core Drilling Rig Rock Geological Core Water Well Drilling Rig Machine For Sale
DR-350 drilling rig is a mechanical top drive drilling equipment integrating water drilling and gas drilling, which solves the difficulty of air drilling with air-dive hole hammer in soil layer, hard rock layer, gravel and pebble layer. Due to the low efficiency of mud drilling construction, the dual-purpose water and gas rig is suitable for various formations, and the efficiency of drilling cores and geological exploration for drilling cores is highly efficient and energy-saving.
Main Technical Features
1.Equipped with hydraulic steel track, the off-road ability is stronger;
2. It is equipped with 4 hydraulic square tube high legs, which is convenient for leveling on site and can save a lot of loading and unloading costs;
3. The drill rig is equipped with a drill rod frame and a foot pedal on the left and right respectively, the design is more user-friendly;
4. The front end of the drilling rig is equipped with an auxiliary rod unloading cylinder, which is more convenient for loosening the drill rod;
5. The hydraulic oil pump and the power are directly connected with a universal shaft, and the rig can climb and move more powerfully;
6. AMT manual-automatic automatic transmission gearbox and electronically controlled shifter are adopted to make shifting easier;
7. The drilling rig uses dual oil pumps to supply oil, and the hydraulic system uses split and merge technology to make the power head rise and fall more quickly;
8. Equipped with folding auxiliary tower, it can lift 2 3m/root gas drill rods at a time.
