ZDY-1900S full hydraulic tunnel drilling rig

1. Brief introductions of ZDY-1900S full hydraulic tunnel drilling rig

ZDY1900S full hydraulic tunnel drilling rig is mainly used for gas drainage, trenchless street crossing, anchor support holes and other construction operations.

ZDY1900S full hydraulic tunnel drilling rig uses all hydraulic power head type structure, which is composed of main engine, pumping station, operating station. It is easy to dissemble and convenient to transport. Also the rig structure is flexible, which makes the drilling process more efficient and effective. The gyrator uses through hole structure. The length of drill pipe is not restricted by the structure size of the drilling rig; When the machine screw and unscrew drill tools, chuck, clamp and oil cylinder, gyrator and gripper can operate in linkage with high automation and high efficiency. the operation is simple and achieves labour-saving.
