Product Feature
GJ-200-4 drilling rig can be used in engineering geology surveys such as railways, roads, bridges, tunnels, dam foundations for water and electricity, civil construction, and pile inspection. It is also widely used in small water well drilling.
1. With hydraulic feeding device, elevated drilling efficiency, reduced labor strength.
2. The rig is equipped with an upper spherical jaw holding mechanism and hexagonal kelly which can be replaced without shutdown, high efficiency, safe and reliable.
3. A hole bottom pressure gauge is mounted indicating the pressure in order to control the status inside the hole.4. Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas. - 【Series】：Spindle Core Drilling Rig
