The viaduct of Yunnan-Guizhou high-speed railway is located in the Yunnan-Guizhou mountainous area.“The natural moat becomes a thoroughfare”The epitome of。November 14, 2023，Sany Pump Truck Successfully Helps the Swivel Continuous Beam Swivel of Bajiacun Bridge across Shanghai-Kunming Railway in Kunming Section of Chongqing-Kunming High-speed Railway Project！Successful reappearance of infrastructure maniac“A bridge flies north and south.，The natural moat becomes a thoroughfare”A feat 。It is understood that，Throughout the project，Sany Heavy Industries sent 49 meters.、52 meters、56 meters、The trump card combination of the 62-meter fuel version pump truck，The overall project has pumped nearly 50,000 cubic meters of concrete.！

The swivel span of the whole line is the largest.、Swivel project of swivel continuous beam with the heaviest weight of single pier，Its construction has high requirements for the equipment involved.，It is not only necessary to ensure the reliability of continuous high-intensity operation，Have to respond to a variety of site emergencies at any time.。 

According to the project manager, Mr. Liu Xiong：In the process of swivel construction，On one occasion, nearly 500 cubic meters of concrete were required to be pumped at one time.，This kind of pumping operation, which requires a long period of uninterrupted time, makes the construction party particularly nervous.。Before project implementation，Including equipment、Maintenance、The mixing station and other parties have held several rounds of plan meetings.，The final decision was unanimous，Adopt Sanyi 49m、52 meters、56 meters、Implementation plan of 62-meter fuel pump truck to ensure construction at the same time。Sany also sent a resident service engineer to watch the work on the spot.，Be ready to solve unexpected situations at any time.。Under a strong safeguard system，The project finally went ahead as scheduled.。

It is understood that，The rotation of the bridge is carried out with two piers as the axis.，A pier girder weighs 1..10,000 tons，The other weighs 10,000 tons.，The pumping operation must be guaranteed to be very accurate，Otherwise, the consequences will be unthinkable。Under construction，All the people are very nervous.，Fortunately, the pump truck withstood the test.，Completed all the operation indicators smoothly and smoothly。

Whether it is the 10,000-ton continuous beam swivel，Or other operations on the entire high-speed rail project?，Sany Pump Truck's performance and excellent after-sales service have been highly recognized by China Railway Fourth Bureau.。Zhang Baozhu, a site manager of China Railway Fourth Bureau, spoke highly of it.“Sany's equipment product quality is stable.，Good after-sales service attitude，And that construction efficiency is improve.，The construction effect is good！”

When asked whether the project will continue to use Sany's products.，Not only did he give a positive answer,，At the same time, he also expressed his strong interest in Sany New Energy Pump Truck.。

The Yunnan-Guizhou section of the Chongqing-Kunming high-speed railway is accelerating the integration of the southwest region into the country.“The Belt and Road”Strategy、It is of great significance to promote high-quality economic and social development along the line.，Sany Heavy Industry will continue to provide high-quality concrete machinery and equipment services for Chongqing-Kunming High-speed Railway.。
