420TA-1 Φ115-138mm Separated DTH Drill 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. It is also applied in infrastructure projects such as highway construction and real estate development, as well as other related industries. Fitted with 3.5-inch or 4-inch hammers, it delivers optimal performance when drilling holes with diameters of Φ90mm, Φ115mm, and Φ138mm, while boasting high drilling efficiency and excellent dust collection capabilities. Thanks to its 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 both domestic and international customers.
