CAROUSEL
​ROD CHANGER

---

• 5+1 rods storage
  
• Easy to operate by manual

ROTARY HEAD

---

​The straight-edge gearbox has a high load capacity, and the rotation speed can be adjusted according to the hardness of the rock. The rotary gearbox is matched with USA Eaton hydraulic motor, and a reinforced shock absorber is installed to reduce the impact reaction force of drilling and improve the service life of the rotary head.

​DUST COLLECTOR

---

• The dust collector system consists of pick-up hood, pre-separator and a dust suction pipe. 
• Can significantly improve the operating environment. 
• Protect the health of drillers. 
• Hight quality filters ensures dust removal efficiency and service life.
• The pulse controller can automatically control the blowing time of the filter element precisely,improve vacuuming ability.​
