GK180-1Drilling 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 71r/min-825r/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. GK180YJ and GK180-1 are designed on the basis of GK180. 1.With hydraulic automatic feeding device, elevated drilling efficiency. 2.Large torque and drilling diameter 3.With a spherical jaw holding mechanism and the rod replacement without breakdown, high efficiency 4.Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.
