Hunan Daily full-page report! "The King of Pumps in the World" is on the top of the tall building



Sany Heavy Industry's ultra-high pressure trailer pump can pump concrete to the top of a kilometer-high building, setting and still holds the world record for vertical pumping of a single pump. From pumping concrete to more than 300 meters in the air to "becoming famous" in Shenzhen, to being crowned "China's Pump King" at 406 meters in Hong Kong's International Financial Center, and then to winning the "World Pump King" crown at 620 meters in Shanghai Tower, the height of continuous refreshment interprets the strength and self-confidence of Hunan manufacturing: "How high the architectural design is, how high it can be pumped".

In early summer, in the center of Xiangjiang New Area in Changsha, the Jin Mao Tower, which is designed to be 318 meters high, "grows out of joints".The concrete pumping equipment that boosts the "growth and height" of the building is "Sanyi Red".As early as 2015, Sany Heavy Industry's ultra-high pressure trailer pump successfully pumped concrete to an altitude of 621 meters above the ground, setting a Guinness World Record for vertical pumping of a single concrete pump.

At present, 70% of the high-rise buildings above 300 meters in China are pumped by Sany pumping equipment; High-rise buildings of more than 500 meters are all pumped by Sany pumping equipment.

"One Pump King"Sany set a new record for single-pump vertical pumping

When choosing the concrete pumping equipment of Jin Mao Building, the construction party did not hesitate to choose Sany Heavy Industry."The experience and successful cases of super high-rise building construction, Sany deserves the first share, we can rest assured!" The person in charge of the construction of the Jin Mao Tower project said.

How to transport the concrete used to build the building itself to a height of several hundred meters?In the past, there was no Chinese brand of pumping equipment used in the construction of high-rise buildings, and even small trailer pumps had to be imported."The price of foreign equipment is expensive, and the service can't keep up, so it's hard to invite an engineer to the scene, and I'm proud of it." Sany engineer Yang Xinhua recalled.

With the dream of serving the country through industry. In 1994, Sany entered Changsha from Lianyuan, entered the field of construction machinery from the field of welding materials, and the first product developed was the tow pump.

After several years of painstaking research and improvement, in 1997, the 60C-1416 model trailer pump of the Sanxia line was the first in China in terms of displacement and pressure. The product was applied to the Capital International Airport for the first time, and the concrete pumping task was completed with high efficiency and high quality, and the industry has been impressed by the domestic pumping brand since then.

On September 21, 2002, the Hong Kong International Financial Center was completed, and the "rookie" Sany, which had only been in the concrete machinery for 8 years, was capped.

This construction opportunity did not come easily. Sany proposes to provide double guarantee during construction, that is, on the basis of the 4 pieces of equipment required on site, an additional 4 machines will be prepared next to it, and if the project cannot be successfully completed, the designated equipment will be purchased for the construction party free of charge around the world.

Seeing Sany's determination and confidence, the construction party decided to give it a try.

In the first battle, the division was unfavorable. When pumping to a height of more than 300 meters, the concrete stagnated. Yi Xiaogang, the chief engineer stationed at the site, hurriedly led the technicians to carefully inspect and finally found the reason: the sealing of the feeding pipe was not enough, the water overflowed, the concrete was in a quasi-solidified state at high altitude, and the pumping was not smooth.

Soon, the problem was solved. Sany finally set a world record for 406 meters of single-pump vertical pumping in the International Finance Center of Hong Kong.

This is the first time that the single-pump vertical pumping record belongs to a Chinese enterprise, and the "King of Chinese Pumps" has fallen to Sany. CCTV promoted Sany's ultra-high pressure concrete pumping technology as a national innovation achievement.

In June 2014, Sany ultra-high pressure trailer pump pumped high-strength concrete to 620 meters in Shanghai Tower, helping it to successfully cap the top, and at the same time pushing the world record of vertical pumping of a single pump to 620 meters, and Sany won the crown of "World Pump King".

Since then, the East Tower of Guangzhou, the Abeno Center Building, the tallest building in Japan, and the Tianjin 117 Building, have ...... These world-iconic buildings clearly depict Sany's journey of constantly challenging new heights, and also witness the completion of China's construction machinery brand from following to running and then to leading.

"One Pump to the Top"Stand on the commanding heights of technology and brand

In 2016, the American Discovery Channel launched the documentary "Magical China", one of which showed the construction process of Sany Pumping Equipment for the Beijing CITIC Building.

In order to complete the pumping task of 528 meters, Sany first conducted a test, and the pipeline alone connected 20 rows with a length of 1,590 meters.At the beginning of the experiment, clean water was first fed into the pipeline as a lubricant, followed by slurry, mortar, and concrete. After 30 minutes of nervous waiting, the first wave of concrete poured out of the pipe outlet.In order to solve the problems that may occur in high-rise pumping, such as slurry leakage, pipe blockage, pipe bursting, pipeline disassembly, assembly and cleaning, etc., Santong will work together to upgrade the pumping capacity of the equipment and solve the technical problems such as pipeline sealing, wear resistance and explosion resistance, and washing of the remaining concrete.

To help build Hong Kong as an international financial center, the reason why Sany dares to fight against the odds is because of the newly developed dual-power merging technology.

This technology solves the problem of undiminished "horsepower" sent from concrete to high places. "It is not simply to superimpose two sets of power and oil pump systems together, but to achieve complementarity, synergy, cooperation, etc." He Zhiwei, director of the vehicle pump institute of Sany Heavy Industry Pumping Research Institute, recalled that during the trial production, the power and pressure of the two systems should be "run-in" over and over again. Pump a height, record a parameter; The height is not up to standard, the parameters are readjusted, and over and over again, sometimes stuck at one height, and there is no progress for several weeks.

"Didn't think about giving up. Looking at the world, no one can do it, we must take it! He Zhiwei said.

In 2014, the Shanghai Tower was capped, and the person in charge of the construction site was worried about the Sany trailer pump hitting 620 meters high, and was ready to pick up a trailer pump 400 meters away from the building.

Sany patted his chest and promised: "It will definitely be able to 'pump to the top'." ”

Prior to this, Sany Heavy Industry set up a R&D team of nearly 100 people to systematically tackle key problems in the super high-rise concrete pumping construction technology of Shanghai Tower.

For example, breaking the traditional "pipeline air washing technology" and creating "ultra-high pressure water washing technology", all the remaining concrete in the pipeline is pumped to the pouring point, and each pipe washing can save an average of 6 cubic meters of concrete, and the whole project can save more than 2,000 cubic meters of concrete.

In the process of technological breakthrough, Sany has stood on the commanding heights of pumping equipment technology and brand faster by digesting and absorbing international advanced technology.

Chen Jing, senior deputy general manager of Sany Group and general manager of construction vehicle marketing company, introduced that Sany has rapidly grown into the world's first brand in the field of concrete machinery, not only replacing imports in China, but also occupying 45% of the global market share, leading China's construction machinery enterprises to rank among the first echelon in the world.

In the global construction sites, such as the tallest building in Ethiopia, the largest thermal power station in South Africa, and almost all major projects in Africa, Sany pumping equipment has participated; In the world's major construction machinery exhibitions, the Hunan construction machinery brand represented by Sany has become a bright business card of China's high-end manufacturing.

"High-profile crossover"Expand from building construction to multiple fields

With the development of super high-rise, large-span and special-shaped structure buildings, the current industry has put forward higher requirements for the strength and durability of concrete materials.

On December 7, 2021, Sany ultra-high pressure trailer pump completed the 380-meter ultra-high pumping construction of machine-made sand C130 ultra-high strength concrete in a key project in Guizhou Province.C130 ultra-high-strength concrete is the strongest concrete at present. If pumping ordinary concrete is "pumping tap water", then pumping C130 grade concrete is transporting "glutinous rice dumplings".

"We not only have to ensure that the 'glutinous rice dumplings' can be delivered, but also to improve efficiency and reduce fuel consumption as much as possible." Chen Jing said that there are no technical barriers to pumping height, and it is a test of equipment intelligence, informatization, energy conservation and environmental protection.

In the No. 18 plant of Sany, the whole process of intelligent production is from the cutting of a steel plate to the completion of the whole vehicle of the pumping equipment. "Sany is currently implementing digital intelligence, electrification, and internationalization transformation, which will create more and more value for customers and society." Chen Jing is determined.

To create more value for the society, Sany has extended its focus to the field of emergency rescue.In 2011, an explosion and leakage occurred at the Fukushima Daiichi Nuclear Power Plant in Japan. Sany refurbished its pump truck to be the only device on site to be equipped with cameras and radiation sensors, and to overcome obstacles to effectively inject water above the top of the nuclear reactor tower.It was this rescue that Trinity got involved in fire rescue.

In 2016, Sany officially crossed over into the field of fire protection. Within 3 years, it has completed the development of 6 types and 20 products such as "super high-rise" and "unmanned intelligence", and the series of products have been distributed to more than 100 fire brigades across the country.

Previously, fire rescue could theoretically reach a height of 100 meters, but in practice, it could not reach 100 meters due to various factors. Sany entered the game, so that the 100-meter fire rescue has a greater possibility of realization.

"Drawing on Sany's ultra-high pressure pumping technology, Sany firefighting equipment sprinkles water to extinguish fires, which can reach any high-rise building." Liao Xianhua, director of the marketing department of Sany emergency equipment, said that the most important thing is that compared with the conventional telescopic boom high-spray fire truck, which can only "cool down" on the exterior wall of high-rise buildings, the Sany large-span high-spray fire truck not only has a long arm span, but also is very flexible.

The reporter saw in the exhibition hall that the 62-meter, 65-meter long-span high-spray fire trucks produced by Sany can be adjusted at will with a folding boom, and the attitude can be adjusted at will, and the high-rise building, the window, and even the indoor obstacles can be crossed, "pointing where to fight", and efficient fire extinguishing; A camera is installed at the end of the boom, which can transmit the fire scene in real time; It is also equipped with a special remote control, which can operate unmanned fire extinguishing by remote control when necessary to ensure the personal safety of firefighters.

"The World Pump King" runs forward unremittingly, acting as a "city builder" in the field of construction machinery, showing the posture of the king; Crossing over to the field of emergency rescue, it has become a "city guardian", aiming to push the social emergency rescue force to a new height and level.
