Brief Introductions of YDX-5C Hydraulic Drilling Rig

The YDX-5C hydraulic drilling rig is mainly designed for prospecting solid mineral deposits. It adopts advanced technology in wire line coring and is driven with rotator. YDX-5C hydraulic drilling rig is widely used in geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries.

Technical Features of Hydraulic Drilling Rig
  • Adopt the world famous hydraulic pumps, valves and motors.
  • There are two kinds of chassis: tyre-traction (with steering gear) and self-propelled steel crawlers.
  • Hydraulic cylinder is adopted for lifting/lowering.
  • When transported and located, the mast can be folded. The mast could work stably with foot clamp touching the earth.
  • Hydraulic drilling rig adopts load sensitive system and is equipped with high-position operation platform and operation hole platform (i.e. low-position operation platform).
  • The rotator is fed and driven with a system connecting the spindle and oil cylinder with chain. It has the following function: if the piston rod of oil cylinder moves one certain distance, the spindle will double the distance. The rotator is equipped with a four-speed gear shift, and hydraulic pressure with stepless speed change can adjust its speed. As to the rig, in its up part, it is equipped with centering guide; in its lower part is a guide. At the operation hole of the lower platform, a hydraulic clamp is adopted.
