845-1 Φ115-165mm Separated Open-pit Down-the-hole Mine Drilling Rig
This series of separated DTH (Down-the-Hole) drill rigs has been primarily used in small and medium-sized quarries, cement mines, open-pit coal mines, and preliminary site preparation for large-scale open-pit mines. They are also applied in infrastructure projects such as highway construction and real estate development. Equipped with 3.5-inch or 4-inch hammers, they achieve optimal performance for hole diameters of Φ115mm, Φ138mm, and Φ152mm, boasting high drilling efficiency and excellent dust collection capabilities. With exceptional flexibility and mobility, this series is particularly well-suited for operations in confined work areas. It has been successfully deployed in mining, military projects, road construction, water conservancy, rock excavation, and other fields, earning widespread recognition from customers both domestically and internationally.
