The UD391H hydraulic development drilling rig for mining is a compact and agile single-boom, electronically controlled hydraulic drilling rig designed for underground mine roadways and engineering tunnels excavation operations, with a maximum working cross-section of 34 m². Equipped with a Sandvik 20kW rock drill, it achieves high-speed, steady-rate drilling in various rock types, effectively extending drill bit service life. The robust LG-B26F drill arm features a 360° rotating thrust beam with an outstanding self-leveling function, providing broader and more optimal section coverage. This enables rapid, stable, and precise tunneling drilling as well as versatile drilling operations.
