Brief Introduction：
The YYG series full hydraulic rock drill is a new high-technology product developed by our company in collaboration with the University of Science and Technology Beijing (USTB). It has obtained many national patents. This machine is composed of two parts: the impact part and the rotation part, allowing for impact and drilling operations to be carried out simultaneously. The machine is used in conjunction with the "KD" series taphole drill machine to drill the tapholes of smelting blast furnaces. It features significant impact energy, short opening times, high work reliability, and easy maintenance. It can meet the taphole drilling requirements of smelting blast furnaces smaller than 2000m³.
