1. Large torque, multiple drilling speeds in an appropriate range
2. The rig has two reverse rotation speeds to facilitate drilling and handle drilling problems.
3. Be capable to slide on the frame of 400mm, giving enough space to handle drilling tolls over the hole
4. High efficiency drilling with hydraulic feeding structure
5. Stable and high strength drilling mast with only a few components, easy to assemble.
6. Multiple usages for geotechnical investigation, wire line core drilling (mineral exploration), hole boring for water well, small size piling hole.
7. It’s Capable to slide on the rig frame to give an empty space to handle the drilling tools it’s also has a mud pump attached on the rig
8. GY-200 has a hydraulic chuck to lock Kelly bar.
Function:
1. Core drill and sampling
2. Small well boring
3. Tower has been advanced to staircase drilling mast, easy to erect, climb, and use, small, more compact and light than previous four column mast.
Tools Applied:
1. General rods in 42mm dia
2. All sorts of barrels that used in conventional drilling:
T2, T6, NMLC, LTK, WF, WG, WM, WG & B single barrel, Chinese single barrel and NQ, HQ barrel(not wireline drilling).
3. SPT tools
4. Other tools that required in the tests and conform to relative international standard such as shelby tubes, bailers etc
