 Control system
  • Main pump for rotary and pull back is Electric proportional plunger pump which is high efficiency, High bearing pressure capability and Long life.
  • Dual speed for rotary,pull back and track moving, controlled by electric proportional control system and continuously variable transmission.
  • All-in-one multifunctional controller, rotary,thrust/pull back as well as other main action. It supplies simple, convenient and comfortable efficient operation.
  • Four-bar swing arm linkage structure provides steep entry angles without raising the tracks off the ground; ensure the stability of drill rig in operation.
  • Wrench skewed 10 degrees inward, towards the operator, easy to observe wrench action.
  • Wrench with buffer spring avoids damage the thread of drilling rod and wrench by human error.
  • Rack-and-pinion thrust structure, the rotary head is driven by double pullback motors and reducers.
  • Steel track with rubber blanket provides high strength and long life;
  • Wire control system for dual speed track moving, safe and reliable.
