KT8 Airhydraulic crawler drilling rig is a carefully research and development of a high efficiency, energy saving advanced drilling equipmentfor small and medium mining,quarry and infrastructure construction projects.it is designed by KT7 drilling rig,update the news function and design

　　Features:

　　1.The overall layout is more reasonable, easy to maintain.

　　2.It uses Cummins 6CTA8.3-260 diesel engine instead of Yuchai YC6A260Z-20,large displacement、large reserve,it can provide greater power in harsh environments

　　3.It usesmultiple pump system by separate controlled,it wilb be higher reliability.

　　4.Equipped with 13/17 single stage high wind pressure screw compression system.

　　5.Its drill arm system increase the luffing angle,it can drill the lowest horizontal hole,thecarriageis design by side directionforbiggerLuffing Angle.

　　6.Oil cylinder-plate chain consisting of a two-speed propulsion system and dual two-speed motor rotary device can suitable for the requirements of different working conditions.

　　7.The jumbo low center of gravity and balanced, equipped with heavy "four-wheel area",with amechanical/hydraulic double brake and big torquemotor, and the frame canbe leveling Angle ±10 °, safe and smooth when walking.

　　8.Drill rig is equipped with high efficient two stage dry dust collection system, greatly improve the working environment,energy conservation,environmental protection.
