Yutong rotary drilling rig, reliable, efficient, low-cost, intelligent incarnation, won 21 national patents; advanced technology to make the machine can drill whatever hard stratum. Except for being able to cope with the efficient construction of sand, clay, silty soil, pebble layer and other common stratum, it is also a “sharp weapon” for construction of complicated stratum such as hard rock and karst after being equipped with impact hammers, compaction & expanding hammers and other drilling tools. It is widely used in foundation construction of bore pile such as high-speed railway, bridges and real estate.
