HDR-G7A fully hydraulic top hammer drilling rig uses a high-power diesel engine, providing strong power capable of easily meeting the demands of harsh working conditions such as high altitudes and extreme cold. Equipped with a high-power high-pressure rock drilling unit from Atlas Copco, it boasts high drilling efficiency. This product is widely used for drilling operations in open-pit mines and civil engineering projects, including earth and rock excavation, quarry material extraction, and slope stabilization.
G7 features a rectangular cross-section folding boom structure driven by hydraulic cylinders, ensuring the flexibility and stability of the drill arm system. The ingenious turntable and push beam support design allow the drilling rig to drill vertical and horizontal holes ranging from 0.3 to 7.6m within a vertical plane, and the horizontal drilling coverage area reaches up to 17m within a planar surface.
