The UD291 drill rig is a compact and flexible single-boom electro-hydraulic development drill designed for drilling tunnels in small to medium-sized underground mine shafts and construction tunnels up to 24 m² cross-section. Equipped with a 20 kW Sandvik LD60 hydraulic drill, it delivers high and consistent penetration rates and extended tool life, even in various rock formations. Its robust LG-B14F boom provides 360° forward rotation, advanced self-leveling, and superior cross-section coverage, enabling fast, stable, and accurate face drilling while supporting numerous secondary applications. The LG-CBI direct-drive hydraulic drilling system with automated functions allows operators to focus exclusively on safe, fast, and accurate drilling operations.
