ZK70 open-pit DTH drill rig is applicable in the open pit engineering required blasting hole in mining, quarries, hydropower, railway, highway and other fields. Compact structure, low center of gravity, flexible, stable work, etc. The rig is driven by a strong and reliable track and has excellent off-road climbing performance. The drilling machine uses hydraulic oil to drive the motor and the big arm, and compressed air to drive the impactor, which cooperate with each other to complete the efficient drilling operation.

· Efficient dust removal filter system, large air volume, strong dust removal capacity, greatly improve the construction environment.
· High strength chain with high torque hydraulic motor, to provide reliable promotion and promotion protection.
· Integrated forming guide rail, more wear-resistant, not easy to deformation.
· The whole machine layout is compact without losing human consideration, easy to maintain.
