Shaft Drilling Jumbo, Pneumatic Shaft Jumbo, SJZ

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. It is powered by pressed air, transmitted by hydraulic system, and all the movements of drill mounting are machine motivated. Equipped efficiency of drilling blastholes are naturally upgraded, thus auxiliary working time is greatly saved.
