HT72-D hydraulic drilling jumbo features compact design, which is used for small and medium sized mines. With flexible design, this mining equipment can be used for drilling horizontal and fan-shaped holes on vertical and inclined plane in underground mine or tunnels.
The underground drill rig features dual drill bits, high precision drill angle indication system, remotely controlled operation platform, and high performance drifter, which ensures drilling jobs are performed in an efficient, safe and quick manner. Thanks to the high-performance drill bits, the drilling precision can be improved largely.
Section range: 3.2×3.2 to 4×4 meters

Huatai is a Chinese company specialized in the design and batch production of rock drilling equipment. Since its inception in 2000, the company has been committed to manufacturing cutting edge products and providing the highest levels of customer service for a number of enterprises engaged in the mining, metallurgical and foundation engineer sectors.
Huatai has achieved continuous self-transcendence and filled several gaps in the domestic market through 20 years of ongoing innovation and development in the underground mining and rock drilling industry. Today, our product line includes more than 30 types of mine rock drilling machines which are fallen into three categories, i.e. underground mining equipment, coal mining equipment and shaft drilling jumbos. Years of our constant growth and improvement have resulted in a respectable achievement in the domestic rock drilling machine industry, increasing the safety, efficiency, and cost-effectiveness for underground mine engineering and tunneling construction operations.
The GYSJZ shaft drilling jumbo is a specialized, high-performance drilling machine developed to meet the demands of deep, hard-rock vertical shaft excavation. The drilling machinery is powered by a robust 132kW motor and equipped with three heavy-duty hydraulic drifters, enabling it to handle drilling diameters from 4 to 6 meters.
YSJZ shaft drilling jumbo is a type of rock drilling machinery specially designed for vertical shaft construction in iron ore and non-ferrous metal mines. The shaft jumbo is a great alternative to be used in mining and underground construction projects where other drilling methods couldn't be adopted due to their technical or economic limits.
SJZ series vertical shaft drill is a special equipment to drill blastholes for construction of vertical shaft. It suits a wide range of shaft diameters, and features of flexible operation, precise positioning and reliable safety.
Purpose-built for medium-hard rock formations, the RC600 hydraulic drifter delivers powerful and precise drilling across a wide range of demanding applications. Its robust design and versatile capabilities make it the perfect choice for support drilling in underground mining, anchor bolt installation, highway construction, bridge engineering, and complex building projects.
