Multifunction KG920A Crawler Drilling Rig
Multifunction KG920A Crawler Drilling Rig
On the basis of KY130, KG930A has been upgraded and improved the
pneumatic system , hydraulic system, drill arm components, and walking
parts and so on, which make climbing abilitystronger, drilling angle more
reasonable .It has faster rotating and feeding speed, longer motor
service time and better reliability.
