Separated DTH Surface Drill Rig
This series of separated DTH drill rigs had been mainly operating at middle or small sized quarries, cement mine, open-pit coal mines and preliminary site preparation for large-scale open-pit mines, as well as infrastructure construction for highways, real estate and other industries.
Drilling depth(m):
21m
The hole diameter (mm):
90-165
Equipped with 3.5-inch or 4-inch hammers, the optimum hole ranges are Φ90mm, Φ115mm and Φ138mm with high drilling efficiency and outstanding dust collection performance. The flexibility and mobility of this series are especially suitable for the construction of restricted working areas, and have been successfully applied to mining and military projects, road construction, water conservancy, rock excavation, and other applications, and have been widely recognized by customers at home and abroad.
