Detailed Product Description

WTZ-150H truck mounted drilling rig is a kind of new type that developed for petroleum, coal and minerals prospecting in complex terrain formation area. The drilling rig is mounted on 4*4 off-road chassis and take-off power from truck engine directly. The drilling rig can drill hole with mud drilling and air drilling. It is the preferred equipment for seismic prospecting in field.
