 HYKD-3-type hydraulic drilling rig scope 
 Hydraulic drilling rig because of its small size, light weight, flexible manipulation, mainly for space exploration in the narrow mine tunnel drilling. Also widely used in other works: railway engineering, hydraulic engineering, tunnel engineering. 
 HYKD-3-type hydraulic drilling rig Features: 
 1, small size, light weight, flexible manipulation. 
 2, power to pump motor direct-drive motor operation and driving tanks, institutions pulled the chain speed delivery. 
 3, all actions, such as drilling rig rotary axis, the fuel tank feeding, clamping and release of the drill pipe are hydraulic transmission, smooth, low noise. 
 4, easy to operate, can be disassembled into small parts, easy handling and installation.
