Features
1. Modular design with maximum unit weight not exceeding 700kg.
2. A spare chassis is supplied, and it can be installed at the next drilling hole before the helicopter transports the disassembled parts to this hole. This can minimize the down time of our geothermal drilling rig by saving time of transportation.
3. 4 speed transmission.
4. Large chuck with diameter up to 117mm.
5. 2m feed stroke of drill head, suitable for 1.5m rods.
6. Independent hydraulic leveling jacks.
7. More precise pressure control of drill head.
8. Universal parts and components.
9. Real time display of drilling data on the control panel.
10. Premium hydraulics from Europe / US.
After-sales Service
