SJZ series vertical shaft drill is a special equipment to drill blastholes for construction of vertical shaft. It has features of reliable, precise, easy to operate, and suits a wide range of shaft diameters. It is powered by pressed air, transmitted by hydraulic system, and all the movements of drill mounting are machine motivated. While using highly effective pneumatic drifter, long propelling stroke, and parallel movement mechanism, the accuracy of drilling blasthole and its efficiency are naturally upgraded, thus auxiliary working time is greatly saved.
