Compact and easy to maneuver, the single boom jumbo is built for anchor holes, small duct holes, exploration holes and small-scale excavation. It is an ideal choice for narrow tunnels.

✔ Small turning radius, easy to move in tight spaces
✔ Full hydraulic control, simple to operate and maintain
✔ High cost performance

Two drilling booms work simultaneously or independently, cutting drilling cycle time and speeding up face advance. A productive choice for medium-to-large underground tunnels and projects that demand higher efficiency.

✔ Up to 2× drilling coverage per cycle
✔ Faster excavation, lower cost per meter
✔ Accurate positioning with stable boom movement

Multi-point drilling across the working face delivers maximum productivity for large-scale underground excavation. Built for large tunnel construction, hydropower projects and mining operations that need high-capacity drilling.

✔ Multi-point drilling for the fastest tunnel advance
✔ Rugged chassis, strong climbing ability
✔ Dust- and water-resistant components
