The LGMRT UD291 is a compact and agile single-arm electrically controlled hydraulic development drilling rig, suitable for small-to-medium sized underground mine roadways and engineering tunnels, with a maximum working cross-section of 24 square meters.
The UD291 is equipped with a 20kW Sandvik LD60 hydraulic rock drill, delivering high-speed, steady-rate drilling in all rock types while effectively extending drill bit lifespan. Equipped with a robust LG-B14F drill arm, its feed beam rotates 360° and features excellent self-leveling capability, providing broader and more optimal cross-section coverage. This enables fast, stable, and precise tunneling drilling while accommodating multiple drilling operations. The direct-control LG-CBI drilling hydraulic system incorporates automated control functions, allowing operators to focus on safe, efficient, and precise drilling operations.
