"To be honest, there were concerns about aftershocks and radiation in Japan. But as a Chinese, I am even more proud to be able to participate in this international rescue with self-developed Chinese equipment! ”

On the afternoon of the 10th, Dai Da'an, a 33-year-old Chinese engineer wearing glasses, arrived in Changsha without a hitch, and was greeted with heroic courtesy: flowers, applause, and the spotlight of countless flashes from the media.

Also returning to China were two young engineers, Zhou Xinan and Peng Yanshou, who also came from Sany Heavy Industry, a private enterprise in China. Their important mission to Japan this time is to train and operate the 62-meter pump truck donated to Japan and provide related services.

Zhou Xinan recalled that at that time, foreign personnel in Tokyo had basically been evacuated, including the US aircraft carrier rescue team and some Japanese locals who were also moving to major cities in the south for refuge. But in order to rush into the rescue as soon as possible, they still rushed to Tokyo, Osaka, Chiba and other places day and night.

As a rescue equipment donated to Japan by a Chinese private enterprise, the 62-meter-long boom pump truck from Sany Heavy Industry is the longest boom pump truck ever used in Japan. Changsha-based Sany Heavy Industry Co., Ltd. took control of what had been monopolized by foreign countries in 1998Concrete pump truckThe company has two unbroken records so far: a 72-meter boom pump truck with a boom length of 5656 in the world, and a pump truck with a concrete delivery capacity of 5656 in the world.

It was undoubtedly a great challenge for the three Chinese engineers to teach the inexperienced Japanese personnel how to condense the task that would have taken three months into two days, and ensure that the pump trucks were put into the water injection and cooling operation at the Futian nuclear power plant as soon as possible.

Dianda said that after repeated research, it was finally decided to conduct the training in a one-on-one mode, with one translator for each; The training content focuses on the most urgently needed aspects such as operation, safety, maintenance, structure, etc. "Due to the short training time, everyone was busy until 12 o'clock in the evening before returning to the hotel to rest, and getting up at 5 o'clock the next morning to continue working."

On March 31, a 62-meter pump truck began to inject water to cool Unit 1 of the Fukushima nuclear power plant, and the temperature of the reactor dropped significantly. The outstanding performance of "Made in China" won high recognition from the Japanese side, and then the No. 2, 3 and 4 units, which were not originally included in the plan, were injected with water by Chinese pump trucks to cool down.

In particular, in order to reduce the harm of nuclear radiation to operators to the degree of *5655, the engineers of Sany Heavy Industry urgently developed long-range wireless remote control technology, and finally realized the unmanned operation of the pump truck at a distance of 2 kilometers. It is said that this technology is currently "unique" in the world.

In the eyes of industry insiders, the outstanding performance of China's pump trucks that rushed to Japan not only means that the machinery manufacturing industry monopolized by Europe and the United States in the past is now holding up the Chinese flag, but also greatly enhances the reputation of Chinese manufacturing in the world.

"Although we have returned to China, the pump truck representing 'Made in China' still sticks to the front line of Japan's post-earthquake rescue and works 24 hours a day, playing an irreplaceable role." Dai Daan said that when he heard the Japanese personnel affectionately call the Chinese pump truck "big giraffe", the pride in his heart was indescribable, and it would be a precious asset of his life to be fortunate to participate in this rescue. finish
