HFDX-2 Full Hydraulic Portable Drilling Rig is a kind of light rig designed for geological exploration in remote area difficult to enter. It is mainly suitable for diamond drilling with wire line coring technique. The rig consists of diesel power unit, hydraulic system, control panel, mast, main winch, wire line winch, drill head, feed system, foot clamp, etc. The rig is completely hydraulic driven for all its surface coring function. Fission style design makes the rig in good assemblability and disassemblability, facilitating transportation to most inaccessible areas. Robust structure plus exact control system ensures high penetration rate and outstanding reliability.
Main technical features:
1. Full Hydraulic and Drill Head model. The drill head rotation is realized with four hydraulic pumps driven by five diesel engines; this also makes the feeding hydraulic cylinder system realize its full stroke feeding in both higher and lower speed.
2. In good disassemblability. The rig is adopted fission style in design, including power unit, hydraulic oil tank, manipulation platform and operation mechanism, i.e. the drilling section. So they are in light weight and can be carried by man power or animal power. The rig can be applied and performed in narrow space for drilling of hole at 45°-90° with stronger adaptability.
3. Strong techniques adaptability. Besides diamond drilling with wire line coring technique, it is in strong techniques adaptability. It is applicable for the drilling and feeding requirement of any other stratum.
