In the construction machinery industry full of difficulties and challenges，There is a secret and outstanding team.，They are a scenic line shuttling through mountains and rivers.，They are a rainbow in the wind and rain.，They stick behind the machinery.，Give life to the machine.，They are the after-sales service team of Sunward Intelligence.。

The beautiful land of Yunnan，Mountains and rivers rise and fall，The geology is changeable，Building a project here has always been a challenging task.。In the near future，A key infrastructure project in Yunnan Province undertaken by China Railway is under construction.，The green equipment of mountains and rivers also shows its skills here.，After the completion of the project，It will further accelerate the traffic flow along the line.，Promote the growth of local economy。

The project area is mainly mountainous plateau.，Bypass、Digging wells has become an indispensable link.，However, the downhole operation only relies on manual operation.，Not only is the labor intensity high，Work efficiency is also relatively low.，Can not meet the needs of safe and efficient production。So，The actual environment of the site was investigated by the Sunward Intelligence team and the project team.，It was decided to use the Shanhe excavator instead of some manual work.。

But the huge machine can not be transported to the underground.，The machine can only be disassembled on the ground first.，And then transported to the underground in blocks.，Reinstall in the well。In order not to affect the overall progress of the project，The project team set a strict time limit for the installation team.：Within five days, all three Sunward Intelligent 135 excavators will be disassembled.、Transport and installation！

Time is tight、The task is heavy、Difficult，To ensure that the installation is completed on schedule,，After receiving the task, the after-sales department of Sunward Intelligence Yunnan Branch held an emergency meeting for deployment.，Formulate“One car, one case”Special policies，Detailed disassembly sequence has been developed for each piece of equipment、Marking method、Difficulty of going down the well、Precautions and installation procedures, etc.，To ensure an orderly installation、Efficiently。

The underground installation of excavators is not an ordinary job.，Requires a high degree of expertise and experience，It also needs strong psychological quality.。This arduous task was carried out by Li Anjun, a service engineer of Yunnan Shanhe.、Guo Zhifei is responsible for the completion，When I got this assignment,，And they did it.“Fight a tough battle”Preparation for，Determined to interpret the service spirit of Sunward Intelligence with their own practical actions，To provide customers with the most efficient protection and support。

“Visibility is extremely low throughout the space.，The light is weak，Oxygen content is low，The ground is dark and damp。”But when you go down to the working face,，The two service engineers were shocked by the harsh working conditions underground.。

In the face of a tight schedule、Heavy tasks and harsh downhole environment，Li Anjun、Guo Zhifei still maintains high morale and firm determination.，According to the established plan，Disassemble immediately、Delivery and installation work，For a smooth delivery，They worked underground for more than ten hours.，Eating and drinking are all done underground.。After several days and nights of continuous fighting.，They lived up to expectations，The installation task was completed ahead of schedule.。

At this point，3 Sunward Smart Excavators Succeeded“On duty”，It replaces the original manual operation.，The construction efficiency of the project has increased several times.，And the labor intensity of front-line workers is greatly reduced.。Coming up，Under the continuous guarantee of the after-sales service team，Sunward Intelligent Excavator Will Contribute to the Development of Yunnan's Infrastructure！
