GK – 200 Type Drilling Rig
GK-200 Drilling Rig with hydraulic feeding is widely utilized and featured in high power and hoisting load (2T), large torque transmission, etc. The rotating speed of vertical hexagonal spindle varies between 66r/min~820r/min. It is suited for the geotectonic survey, geological core drilling, small hole drillings for grout, blast and water well in railway, water conservancy, bridge, dam foundation and other constructions. Diamond drill bit, alloy drill bit and steel roller drill bit are available for drilling according to different geological structures.
