Product Description

Our KG series borehole drilling rig is an updated version of our KY series hole drilling machine. The previous simple structure and reliable performance remain the same. However the hydraulic system, walking components, gyrator, driving system, pneumatic system, drill arm components, carriage components, and so on, are all optimized or updated.

As a kind of professional blasthole drilling equipment, this borehole drilling rig can be widely used for rock blasting operations in many cases like small or medium open-pit mines, water conservancy project, hydropower station building, road construction, and so on. The suitable rock hardness is in the range of F = 6-20. The diameter of the hole could be from 80mm to 165mm, while the economical drilling depth is 10-25m.


The KG920A medium pressure crawler drilling rig is an updated version of KY125 series rock hole driller. The pneumatic system, hydraulic system, drill arm components, walking parts are all optimized and upgraded. Thus the machine has stronger gradeability-the steepest slope could be in 30°. Besides, the rotating speed could be from 0r/min to 107r/min.

A detailed comparison between the KG920A and KY125 drilling machinery has been made in the form below. If you are interested in it, just contact us at any time.
