Our hydraulic drilling jumbo is equipped with a compact structure, small external dimensions, energy efficiency, low noise, multifunctionality, and high efficiency, enabling mechanized operations in rock tunneling and significantly improving excavation speed.

Suitable for tunneling operations in various underground passages and culverts, such as those in metal mines and hydropower projects, this equipment features a fully hydraulic drilling system and an anti-jamming function for drill steels.

The entire series of drilling jumbos offers excellent maneuverability, a small turning radius, and a climbing capacity of 14°, ensuring both construction efficiency and quality.
