At 9:30 a.m. on August 3, a steel beam was hoisted into place at the back of Shanghai Tower*, realizing the capping of the 580-meter main structure, and China's *5656 high-rise building was born. It is understood that during the construction of Shanghai Tower, up to now, a total of 23 Sany pumping equipment have participated in the operation, pouring 60,000 square meters of floor plate and pouring more than 90,000 square meters of main structure. Among them, the "China Pump King" once again created a new height of single-pump vertical pumping, reaching 580 meters.

The 580-meter China Pump King has set a new height for single-pump vertical pumping

"I've been in this business for more than 20 years, and I used to use foreign brands. But the emergence of Trinity has changed this situation. Shanghai Construction Engineering began to use Sany Pump in 2003, Sany Pump has done a lot of big projects with us, 70-80% of the landmark projects in Shanghai are completed by us, such as the 492-meter Shanghai World Financial Center next to it, Sany products are really good, and the service is good. ”

Xue Zhengming is an equipment supervisor at Shanghai Construction Engineering and was involved in the construction of the Shanghai Tower. At the construction site, he pointed to the Shanghai World Financial Center near the Shanghai Tower and said: "I have been involved in the construction of most of the high-rise buildings in Shanghai, and the pumps we used in the past were all foreign, and their products were good at that time. But we found that if the material is coarse, they will not work, and they will not be able to hit. In comparison, I still think Sany's pump is good. ”

Speaking of Sany Trailer Pump, Xue Zhengming told a story to reporters. At that time, the person in charge of Shanghai Construction Engineering was unsure of how high the Sany tractor could play. "We're going to pick up a trailer pump 400 meters from the building and put it up." The person in charge revealed this idea to Sanyi Yi, and the person in charge of the Sany Research Institute patted his chest to ensure that the Sany tow pump must be able to "pump to the end", and there is no need to take another tow pump halfway.

Out of trust in Sany, the person in charge of Shanghai Construction Engineering chose the W* brand product developed by Sany at that time - HBT90CH2150D ultra-high pressure concrete pump. The outlet pressure of the ultra-high pressure pump is as high as 50MPa, and the power of the whole machine is (273×2) kW, which can achieve double guarantee in the output pressure and the power of the whole machine in the process of pumping construction of ultra-high-rise buildings, and the theoretical pumping height is more than 800 meters.

"After more than 1,700 days and nights, the quality of Sany Trailer Pump is stable and the pumping capacity is strong, which makes us very worry-free." As a loyal fan of Sany products, Xue Zhengming is amazed by the HBT90CH2150D ultra-high pressure concrete pump. "Especially in the high-temperature environment, the Sany tow pump does not burst or block the pipe."

In addition, the capping of the main structure of the Shanghai Tower also means that the vertical pumping capacity of a single pump of the "China Pump King" has reached 580 meters, creating a new height.

　　150,000 square meters and 23 sets of Sany equipment poured into Shanghai Tower

Completed in 2014, the Shanghai Tower is located in Shanghai's Lujiazui financial center district, covering an area of more than 30,000 square meters, and is a comprehensive building integrating offices, hotels and tourism. After completion, it will form a "product" shaped super high-rise building complex with Jin Mao Tower and Shanghai World Financial Center.

The Shanghai Tower, which is topped out by the main structure, is built on a two-storey floor with an area equivalent to 1.6 standard football fields. The amount of concrete poured from this floor slab is equivalent to the first quarter of the world's financial center, which is the largest volume of the world's civil building floor volume.

At the end of March 2010, 18 sets of Sany equipment were under construction here. After more than 60 hours of day and night fighting, 12 pump trucks, 4 trailer pumps, and 2 unitsOn-board pumpsSuccessfully completed the task of pouring 60,000 square meters of concrete.

"In more than 60 hours, more than 60,000 square meters of ultra-high-strength concrete were pumped uninterruptedly, which is a great test for the pumping equipment in terms of construction scale and pumping difficulty." In the eyes of industry users, "the uninterrupted pumping of 60,000 cubic meters of ultra-high-strength concrete, which was unthinkable in China before." Even in the world, it is rare. ”

In April of that year, after the pouring of the bottom plate was completed, 3 Sany trailer pumps and 2 distribution rods began to transport high-rise concrete. As of August 6 this year, the concrete pouring of the core tube of the 123rd floor and the outer wall of the 110th floor of the Shanghai Tower has been completed, pouring more than 90,000 cubic meters of concrete.

It is understood that the strength grade of the concrete pumped this time is C60, but after the concrete is added with admixtures, the actual pumping concrete strength grade reaches C100. "If pumping ordinary concrete is like pumping tap water, then pumping ultra-high-strength concrete like C100 is pumping asphalt." Users in the industry told reporters that high-strength concrete has very high requirements for pumping equipment.

With such a large national key project and such a difficult project, the contractor, Shanghai Construction Engineering, chose all 23 pumping equipment from the Sany brand. The person in charge of Shanghai Construction Engineering said: "If it were not for the full trust in the quality of Sany for many years, we would definitely not dare to do this." ”

　9 super high-rise buildings in China 80% are pumped by Sany equipment

According to statistics, so far, the country has built and is building high-rise buildings distributed in Shanghai, Guangdong, Hong Kong, Taiwan, Liaoning and other places, Sany pumping equipment participated in the construction of 9 of the buildings, accounting for nearly 80% of the country's ultra-high-rise buildings. The skyscrapers above 500 meters in China are all built by Sany Equipment. As a result, Sany Heavy Industry has established a relatively leading position in the field of super high-rise pumping in China and even in the world.

As far as the eye can see, the Shanghai World Financial Center, adjacent to the construction site of the Shanghai Tower, is still eye-catching. The 492-meter-tall building*5656 in today's China was also built using Sany equipment and set a world record for single-pump vertical concrete pumping at the time. Yi Xiaogang, chief engineer of Sany Heavy Industry, once proudly said: "How high the building design, how high the Sany equipment can pump." Today, Sany Pump has once again set a new high of *5656 in China.

Hu Jianhua, deputy general manager of Shanghai Construction Engineering *5656 Construction Co., Ltd., said, "In terms of actual results, it is indeed like Sany's commitment, Sany's equipment is the best in China in terms of service, cost performance and process maturity, and we hope to work together with Sany to continue to complete the Shanghai Tower project." ”

Hu Jianhua told reporters that in addition to the concrete equipment to participate in the construction of Shanghai Tower, Sany has also set up a special service team to enter the construction site to provide "user-level" services around the clock. While Sany equipment is continuously constructed day and night, the service personnel also guard the construction site and fight continuously, not letting go of the slightest equipment abnormality to ensure that the construction is foolproof.

According to Lin Zixi, a special service engineer at the "squatting" construction site, up to now, Sany equipment has not had any major failures except for the normal replacement of wearing parts. "The entire construction project may be completed before the end of this year, and after the main structure is capped, Sany Equipment will also be responsible for the concrete pumping task of the perimeter wall."
