Since Schwing produced the world’s first concrete pump truck, it has occupied an important position in global construction machinery and has become a piece of indispensable heavy machinery in various engineering constructions.

The main function of the pump truck is of course to pump concrete. It solves the problem of continuous concrete pouring in large-scale engineering construction, reduces labor, and greatly improves construction efficiency. However, as a special machine, modern pump trucks have already achieved more uses, such as fire fighting and disaster relief.
In fact, Americans began to modify pump trucks a long time ago for firefighting purposes. You only need to add a pressurizing joint at the end of the boom. Since the boom of the pump truck uses wireless remote control, the operator can stand at a safe distance, control the boom of the pump truck, and spray high-pressure water from the end, or Other fire extinguishing materials. Compared with traditional fire trucks, the structure of the boom of the pump truck is more flexible, and the length of the boom can also be longer.

In fact, there are similar attempts in China. In 2018, on a construction site in Aksu, Xinjiang, local firefighters successfully converted a concrete pump truck into a “high jet fire pump truck”. And compete with a traditional high-jet fire truck at the scene to see who has the stronger fire-fighting ability. In the end, the advantages of the concrete pump truck are obvious.

More importantly, it takes at least 1 million to purchase a regular high-spray fire truck. If it is modified directly by the pump truck, a large amount of cost can be saved. Because the number of pump trucks in each place is relatively large, and the domestic pump trucks are mainly 47-meter, 52-meter, and 56-meter long-boom pump trucks. When a big fire occurs, these social Participated in the rescue work, the concrete pump truck is also a very important rescue force.

The advantage of the concrete pump truck is that the boom can be bent and folded, and the boom can be directly injected into the center of the fire source to spray high-pressure water. And there is no need to lift the firefighter up and put out the fire manually like a traditional high-jet fire truck. If a second danger occurs, it is not conducive to the escape of the firefighter. Therefore, the advantages of turning a pump truck into a fire truck are still obvious.

The Germans also studied the case of turning a pump truck into a fire truck a long time ago. For example, the Schwing pump truck with the Mercedes-Benz chassis above has a pressurized connector at the end of the pump tube, which can make the sprayed water more pressure.
This high-jet fire pump truck developed by Sany has a horizontal span 1.6-1.9 times that of a conventional telescopic boom high-jet fire truck, realizing a longer range of fire fighting. And it also uses remote control operation, the spray head is equipped with a visual camera, and the real situation of the fire scene can be clearly seen through the wireless transmission of video signals. This kind of high jet consumption pump truck can prevent firefighters from entering the fire scene, but can also control the fire in time, which is indeed safer and more reliable.

In addition to fire fighting, concrete pump trucks also have good applications in disaster relief. For example, on March 11, 2011, due to the Fukushima Nuclear Power Plant crisis induced by the Great East Japan Earthquake, Sany Heavy Industries donated a 62-meter concrete pump truck to participate in the cooling water pouring work of the nuclear reactor.
However, currently Sany Heavy Industry has developed a new large-span elevating jet fire truck based on the characteristics of fire trucks. This time it is not a simple modification, but a high jet fire pump truck tailored to meet the needs of daily fire fighting.
Sany has its own patented technology for long-boom pump trucks. Although Japan’s heavy industry is very developed, in the field of long-boom pump trucks, Japanese local products seem to be unable to find the length of the boom needed to cope with the crisis. Therefore, the Japanese government turned to the Chinese brand for help, and Sany appointed a 62-meter concrete pump truck to participate in the rescue mission.
It seems that it is simply pouring water onto the nuclear reactor, but in fact, the performance requirements for the pump truck are very high. Because this process needs to be carried out continuously and uninterrupted, it tests the overall pumping performance of the pump truck, and it is also a big challenge to the durability of the hydraulic system. However, Sany’s pump truck completed the task very well. Since then, the Japanese government has also purchased a batch of pump trucks from Sany. One expresses its gratitude, and secondly, it also affirms the quality of domestically-made pump trucks.
Sany is not the first brand to send pump trucks to participate in the rescue of nuclear power plant leaks. Prior to this, Putzmeister’s pump trucks had also participated in the rescue work of the Chernobyl nuclear power plant. The advantages of the long-boom pump truck in this field are still very obvious. At least nuclear radiation has no side effects on the pump truck, and the operator can remotely control the boom, which is simple and convenient.

Many times we are talking about technological innovation and product extension. The conversion of a concrete pump truck to a fire pump truck is actually a good start. Every time we hear reports in the news that our young firefighters have lost their lives because of fires, we always feel sad that we need this kind of equipment that can better ensure the safety of firefighters. If it were you, would you be willing to transform your pump truck into a fire rescue truck in an emergency?
