CMM2-5 hydraulic bolting jumbo comes with compact design, making it suitable for bolting and drilling works on narrow drifts and tunnels. Due to the small footprint, the drilling equipment is allowed to work with other rock machinery at the same drifts or tunnels without affecting their operations. It is only Featuring a height of 2030 mm, this jumbo drills can easily travel through most mines.

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.
CMM2-33 hydraulic bolting jumbo is built for rock reinforcement in underground coal mines. It's especially suitable for bolting on rocks with strength smaller than f-8. Working together with a production drilling jumbo, this rock bolting rig is used for drilling holes for placing rod bolts and cable bolts.
