Get Operation Manual

KGH8 surface DTH drilling rig is a self-propelled hydraulic drilling machine which is carefully designed by using mature hydraulic technology according to mining requirement. It is featured by beautiful appearance, easy operation and stable performance. Through optimal hydraulic component configuration, it is applied to drilling operation in different rock stratums. With large four-cylinder Commins motor, it is also applied to the drilling operation at high elevation. Large torque rotation reducer provides strong rotation torque to meet the requirement for drilling large diameter and deep holes. Therefore, it is an ideal machine for open-pit mining, road construction, and tunnel excavation projects. It is equipped with drilling dust collector to clean drilling operation environment and reduce pollution to the environment.
