HT81/2 hydraulic drilling jumbo with two booms is Huatai’s latest product manufactured for small and medium-sized mines and various tunnels. It can operate in tunnels with a cross section upwards of 45m².
The drilling jumbo adopts a fully hydraulic rock drilling system and anti-jamming devices to secure an efficient and rapid function.

The HT221 hydraulic drilling jumbo is purpose-built for tunneling and excavation in narrow underground spaces, including metal mines and other confined environments. With a coverage area of up to 33 m², this intelligent tunneling jumbo delivers high-efficiency performance through its advanced full-hydraulic rock drilling system equipped with an anti-jamming mechanism for faster, more stable operation.

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.

Our hydraulic drilling jumbo is widely utilized in small to medium-sized underground metal mines, hydropower projects, highway/railway tunnels, and chemical industry applications. With exceptional rock adaptability (handling Protodyakonov hardness levels of f=6-16 or higher), this versatile machine operates efficiently in tunnels as narrow as 3.3 meters wide.

Our hydraulic drilling jumbo is specifically designed for efficient excavation in narrow tunnels and underground passages within metal mines and other subsurface engineering projects.

HT83-D hydraulic drilling jumbo has been engineered for various mines and small sized drifts & tunnels, with drilling coverage range of 2000x2000-2800x2800mm (WxL).
The drilling machinery comes with fully hydraulic rock drill system and anti-jamming function, allowing for quick drilling speed with low consumption. The drilling jumbo is featured by compact structure and great mobility.
