“A horse race on the mountain，A slippery cloud.，Duan Duan Liu Liu Shines on，The city of Kangding.……”A song《Kangding love song》Let people know.“Kangding”This famous historical and cultural city。In the near future，Sunward intelligenceSWDMThe 420 rotary drilling rig is working on Zheduo Mountain at an altitude of more than 5000 meters in Kangding.，Booster gold——Hubei UHVDC Transmission Project，“Sing”Another Different Song of Kangding。

It is reported that，Jin Shang——Hubei±The 800 KV UHVDC transmission project is the seventh UHVDC project in Sichuan.，It is also the highest UHVDC transmission project in the world.，It is responsible for transmitting the electricity of hydropower units in the upper reaches of the Jinsha River to central China.，It is estimated that 40 billion kilowatt-hours of electricity can be transmitted to central China every year.，It's our country“Power transmission from west to east”One of the major arteries。 

The project is a typical plateau project.。Site construction environment is harsh.，Hypoxia、Low pressure、High cold、High altitude，At the same time, the geological conditions are extremely complex.，Containing granite and other hard rock components，In addition, the ecological environment is extremely fragile.，It brings great challenges to homework.，In particular, it is easy to cause difficulties in tooth insertion.，It puts forward higher requirements for equipment performance.。Qinghai Power Transmission and Distribution Company Faces Complicated Geological Construction，Be very careful when choosing equipment，Through the geological analysis of the area,、Equipment comparison analysis and simulation exercise，Finally, he chose Sunward Intelligence.SWDM420 rotary drilling rig。

Sunward intelligenceSWDM420 rotary drilling rig is praised by customers as“Into the rock expert”，The structure of the whole machine is solid、Stable and reliable，Adopt large diameter slewing bearing、Double brake、High strength and high rigidity platform、Reinforced double-large-width movable arm luffing mechanism、Large-section high-rigidity mast，Equipped with high-power engine、Large displacement main pump、Three-motor power head，Reasonable power matching of power system，It has strong power、The torque is large、Fast speed and other advantages，The transfer transportation is convenient，The maintenance is more convenient。

“Among the two towers with the highest elevation,，The 8 hardest piles are granite geology.，Rock uniaxial compressive strength up to 130 MPa，Pile length 16m、Pile diameter 2.2 meters，OursSWDM420 continuous construction for more than 40 days，Complete the task successfully，Its excellent performance has been fully affirmed by customers.。”Feedback from construction site personnel，Sunward intelligenceSWDMThe construction of 420 rotary drilling rig is progressing smoothly in this project.，It is favored by customers。

Sunward Intelligent Rotary Drilling Rig shows the hard core strength of piling machinery on the plateau.，Help our country“Power transmission from west to east”Engineering。Future，Sunward Intelligence will continue to play“Pilot innovation”Advantage，To provide customers with a more professional set of solutions，Bring more perfect construction experience，For national infrastructure、Make new contributions to economic development！
