In recent years, there are many tall buildings in the world, and China accounts for half of the world's top ten skyscrapers. How can the concrete be transported when the tall buildings are built so high? This requires China's 101 meter long boom pump truck, which has 120 patented technologies. The 101 meter long boom pump truck can reach the 30th floor with one hand, China's manufacturing technology has been creating new records, and the equipment made in China will always be so powerful.

Especially the innovation of infrastructure equipment, we take the concrete pump truck as an example. Eight or nine years ago, China developed the longest boom pump truck, with an arm length of 101 meters, breaking the Guinness world record. On September 28, 2012, this pump truck was successfully offline in Hunan. What is the concept of 101 meters? You can reach 30 floors if you reach for a building below 30 floors, Concrete pump truck can be used for pouring construction, which completely rewrites the inefficient need to repeatedly change the way of concrete pouring in 30 storey buildings, and 95% of high-rise buildings are within reach.

The completion of Wuhan Huoshen mountain Leishen Mountain hospital is the use of Zoomlion pump truck and sany's 56 meter concrete pump truck. These concrete pump trucks have helped a lot, so why is it a concrete pump truck. It is used to transport concrete and accurately transport concrete to the specified position through the boom system, which can not only ensure the quality but also improve the speed.

In the late 1960s, Germany developed a 16 meter long boom pump truck, which caused a sensation all over the world. After more than 20 years, Germany developed a 62 meter long boom pump truck. It can be seen that European enterprises have established a deep technical foundation and formed a complete industrial chain in this regard,

Since the 1950s, China has been developing and imitating concrete pump truck for 30 years, and it was not successful until 1982. This was only successful after cooperating with Japanese companies. The towed concrete pump truck developed in cooperation with Japan was successfully developed and put on the market. Overtaking on curves is our strength. With the development of high-rise buildings in the world, The demand for long boom pump truck in the construction market is becoming increasingly prominent.

China has also lived up to expectations. In September 2011, Zoomlion produced the world's longest 80m carbon fiber boom pump truck. In a short year later, Zoomlion once again announced the birth of 101m long boom pump truck, which is another miracle in the history of pump truck design.

The off-line of this boom pump truck caused an earthquake in the industry. At that time, industry experts predicted that this record would exceed 101 meters in at least five years. This pump truck used 120 patented technologies and carbon fiber technology. The total weight of the pump truck is reduced by more than 15%, with high strength and long service life, which greatly reduces the maintenance difficulty of the pump truck. This is also the first time in human history that carbon fiber is used in the field of construction machinery.

At that time, the technology of the United States, Germany and other industrial powers was still stagnant in the 1980s. China's advanced development in this regard showed our strength in infrastructure construction. The concrete pump truck was installed on the heavy truck, and the pumping system, hydraulic system, electrical control system and boom system were installed on the top to transport the concrete to a certain height or distance, The function of the arm support system is to complete the transportation of concrete. The crane supporting it needs to ensure that the concrete can be transported safely.

The main component of the system is the turret of the distributing rod. The pumping system is the actuator of the concrete pump truck, which is responsible for transporting the concrete to the pouring place through the pipeline. The site is mainly composed of hoppers with pumping structure and lubricating structure. The electric control system uses power to transmit the operation instructions to the machine. Each component is mainly composed of remote controller and sensor. The hydraulic system changes the pressure, To realize energy conversion, the booster is mainly composed of oil pump, oil tank and boom pump. It is known that tower crane is needed to build high-rise buildings, but concrete materials are indeed transported by boom pump truck.

First of all, the boom pump truck puts the concrete into the hopper of the pump truck, then sends it to the transmission pipeline by the pumping system, and finally discharges it through the hose. This is a modern technology. It is precisely because of the convenience provided by various modern equipment that it can have the speed of China's infrastructure. Will such a long boom be very heavy and not as easy to use as the short boom.

In fact, the lighter the pump truck is, the better. The heavier the boom is, the greater the load it will bear, which is more likely to cause fatigue and deformation of the boom material itself, so as to shorten the service life. In terms of energy conservation and emission reduction, the heavier the boom is, the greater the pressure of the boom oil pump when the boom is deployed, so the power consumption of the pump truck engine will also increase.

Relevant data show that the weight of the boom is reduced by 1% and the fuel consumption of the engine can be reduced by about 0.8% ~ 1.1%. The 101 meter long boom designed by Chinese engineers is light and made of carbon fiber, although it is very long.

Since the 101m long boom truck was launched in China in 2012, no machine can surpass it. At present, China's long boom crane occupies the top four in the international ranking. The fourth is XCMG's 75m long concrete boom pump truck. Hb75k pump truck is XCMG's strongest concrete boom pump truck. The pump truck has passed the experimental inspection and poured 550 cubic meters of concrete, It is also the best performance of long boom pump truck in practical application.

The third place is the 80 meter long CF concrete boom pump truck. At first, it was the largest concrete machinery manufacturer in Italy. In 2008, investors such as Zoomlion Heavy Industry invested 270 million euros and completed the acquisition of 100% equity of CF.

Therefore, CF is currently a foreign sub brand of Zoomlion in the world concrete machinery market. It has patented carbon fiber boom pump truck and 80m pump truck. The last arm is made of carbon fiber material, with lighter weight and higher strength. It ranked first among the global concrete machinery brands at that time, and its own technology research and development ability is very strong.

The second is the 86m concrete frame wall pump truck, which was launched by Sany Heavy Industry in 2011. At that time, it had obtained the Guinness world record certification. It was the strongest boom pump in the world at that time. It was composed of seven boom sections, and it was also the pump truck with the largest number of boom sections at that time.

In 2011, there was a nuclear leakage accident in Fukushima, Japan. Japan hoped that Chinese enterprises could provide emergency help. A concrete boom pump truck was used for high-altitude water delivery and cooling to Fukushima nuclear power plant. Why did they go to China for help? At that time, Japan could only produce pump trucks with boom length less than 50m, But they need a pump truck with a boom length of at least 56 meters to supply water to the nuclear power plant.

At that time, only Chinese companies in the world could produce the longest 72m long arm pump truck, which was more reliable. The pump truck can be operated by wireless remote control 2 kilometers away, which ensures the safety of operators. Sany Heavy Industry delivered the crane to Japan, together with two consultants and enough accessories. The pump truck played a very important role in Fukushima rescue.

Of course, the first one is the 101.18m boom length of Zoomlion. In terms of boom crane, Zoomlion has CFO's carbon fiber boom technology. Therefore, the boom length of the pump truck has increased by leaps and bounds, which is 15 meters longer than the longest concrete boom pump truck of Sany Heavy Industry. The three end section adopts carbon fiber technology and is lighter. In addition, the vehicle uses Scania general truck chassis.

In everyone's impression, a big guy like the long arm pump truck should be a heavy machine, but it is actually a very precise equipment. The frame wall is a key component, which should not only reach the height of tens of meters or even hundreds of meters, but also bear the huge pressure when pumping concrete. Therefore, the steel plate strength of the frame arm exceeds 600 MPa, which is equivalent to an elephant on the fingernail, Now we know his value.

In addition, it is equipped with a precision automation system, which can accurately transport the concrete to the specified position and control the direction and speed. The key is safety. There is no shaking during transportation. The concrete pump truck can accurately transport the concrete in both horizontal and vertical positions, whether in a wide space or a narrow environment, not only in construction engineering, but also in construction engineering, The protection of workers has played an important role. Now the construction of buildings we build is higher and higher, and the construction speed is faster and faster.

Concrete pump truck plays an irreplaceable role, so the scientists who developed concrete pump truck are very amazing.
