Features
  • ZP-30DB drilling rig has strong driving ability of hoisting, rotating and circulating. And it also has high control accuracy, high overload reserve coefficient and much safety protection.
  • Hoisting, rotating and circulating speed can achieve stepless regulation. In addition, it shows high transmission efficiency and short auxiliary operation time.
  • It has less spare parts, besides, the maintenance process is simple and overhauling is easy.
  • ZP-30DB drilling rig covers less area, needs fewer transportation vehicles and has short relocation period. Besides, it's convenient to assemble and disassemble blocks.
  • Electricity or diesel oil can be used. Using electricity can save energy for over 50% and using diesel oil can save over 30%.
  • The parameters can be displayed, early-warned, recorded, stored and transmitted in real time. Moreover, mud logging function is also equipped.
  • It can be used safely and comfortably. And labor amount, labor intensity and risks are reduced greatly.
