Small Portable Hydraulic 180 Meters Mine Borehole Water Well Core Drilling Rig
Features:
- 1. It is characterized by high rotation speed and it is applicable to core drilling with small-caliber diamond drill bit.
- 2. Its hoist adopts a combination of friction cone and planetary gear, with advanced structure. It is suitable for percussive drilling.
- 3. Hydraulic feeding, easy to operate and high drilling efficiency.
- 4. Its structure is compact, and the pump is mounted on the drill bottom frame, which occupies a smaller area.
- 5. The rotary table adopts a T-shape groove angle changing range; therefore the drill rig is capable of drilling with various inclinations.
- 6. No exposure of bevel gear for the case opening, which enables the accuracy and reliability of the falling-in of gears, free from any pollution and with a long service life.
