High air pressure crawler open-air DTH Drill Rig has the advantages of low energy consumption, high efficiency, convenient field performance and transportation, the machine actions are realized by hydraulic system, only DTH hammer uses wind, so it greatly saves the cost for air compressor. The new type of rotary power head can supply and maintain strong rotary torque output during the blasting hole drilling construction. When this drilling machine dragging air compressor, they are flexibility, strong climbing ability, suitable for rugged field operation, and convenient for holes drilling.
