HSD**0 Open air highpressure crawler Down the hole drill rig is a largesized openair engineering equipment. 



Hole diameter: *6 to **5 mm

Hole depth: *0 m



This product is mainly applied to the drilling operation of small/middlesized holes in the openair mining project and also the slope anchoring operation of rock project. This drill rig is equipped with engine power and full hydraulic drive hydraulic system to move and transform the machine through the travel system of crawler chassis and shift and adjust the borehole angle and position through the positionshifting system. 



The rotation of drill pipe is driven by the lowspeed big torque motor and pushed by hydraulic motor sprockets and it is equipped with the highairpressure Down the hole drill hammer to complete the drilling operation. The drill tool is of the multidirectional shifting function and hydraulic rodbreaking function and it is characterized by compact structure, advanced performance, high efficiency and low consumption, higher reliability, convenient operation and maintenance.
