Hebei Guomei: Tunnel drilling rigs for coal mines, hydraulic drilling rigs, meter drilling rigs, meter drilling rigs, the first drilling rig company in Hebei. It is a product of our Hebei Shijiazhuang coal mining machine and is also the birthplace of drilling rigs. If you want to get detailed product introduction and parameters, please log on to the company website and contact us as soon as possible. The series of coal mine tunnel drilling rigs have an overall box-type structure. The whole machine is small in size, light in weight, easy to move, and convenient for transportation and installation in small-section tunnels. The transmission mode adopts mechanical rotation, hydraulic feed, and hydraulic chuck, with compact structure and high efficiency. By replacing some parts, drill pipes can be used. The drilling rig system is simple and easy to operate. It is at the domestic leading level in terms of drilling capacity, drilling efficiency, safety and reliability.
The series of drilling rigs are mainly composed of power head, gearbox, drawworks, brake, chassis, control panel and drilling tools. According to the on-site use requirements of Fengcheng Mining Bureau, the partial design of the drilling rig has been improved. Eliminate winch components.
