HYQB-8 drilling rigs are split portable full hydraulic core exploration drilling rigs designed for medium and deep holes in difficult-to-access areas to meet the requirements of green exploration.
Technical Features The hydraulic system adopts a closed + open system, which improves the system efficiency and power utilization rate; the power head adopts a combination of mechanical + hydraulic stepless speed regulation, and a single variable motor can achieve different torque ranges and adapt to different formation drilling requirements. ; The hydraulic system adopts gear pump, which improves the system pressure and increases the drilling capacity under the same structure; the feeding adopts the double guide rod method, which simplifies the structure and increases the stability.
