New Hainan Client, Nanhai Network , Nanguo Metropolis Daily , October 28 (Reporter Wu Yuewen, Correspondent Zhang Tongming, Xu Binru, Zhu Wenzhe, Text and Picture) On October 25, the combination of Mengtian Experimental Cabin and Long March 5 B Yao-4 launch vehicle was transported to the launch area. On the day of transportation, the blue door of the rocket vertical assembly and testing plant of Wenchang Aerospace Launch Site slowly opened, and the "Long March 5 B", the rocket with the strongest low-orbit carrying capacity in my country, made its domineering debut. This is its third time to be responsible for the capsule launch mission of the space station.

Time went back to more than a month ago, the Changwu B rocket arrived at Wenchang by sea. At that time, this great power's heavy weapon was still an arrow body packaged in multiple containers. How to assemble heavy equipment from a great country? Who completed this critical process? On October 28, the reporter interviewed the "arrow casting division" in the construction and launch testing team of the Wenchang Aerospace Launch Site - the rocket hoisting team.

After the rocket segmented arrow body arrives at the launch site, it is first necessary to go through the "horizontal reprint and unload the truck" procedure before it is considered "settling". The commander of the rocket hoisting team and 12 trumpeters lift the arrow body by connecting the spreader and controlling the crane, and move it horizontally to the bracket car. During the movement, the trumpeters will control the ropes at their respective points to prevent the arrow body from shaking greatly to avoid bumps, until all the arrow body modules are reproduced in the level test hall.
"After the control system, power system, and measurement system prepare the horizontal state of the arrow body module, the task process enters the 'highlight' of vertical assembly." said Cui Zishun, a crane operator in the rocket factory.

vertical assembly is the most critical step in the entire lifting work. Gao Peng, commander of the rocket lifting system, introduced: "The research and development of the Long March 5 B rocket has achieved a breakthrough in my country's low-orbit carrying capacity of 25 tons, but we must also see its huge size, with a boost diameter of 3.35 meters and a rocket core stage diameter of 5 meters. The huge size of the arrow body puts higher requirements for the lifting work."

Multiple segments of arrow bodies are assembled step by step in a limited space, requiring the lifting team to have extremely high tacit understanding and skillful and precise operation. Commander Gao Peng has a unique understanding of this. He said that the Rockets need to be taken seriously and seriously. Once the arrow body is lifted and suspended, the force points of each key point must be stable. At the same time, the commander and the telcoder must report back and forth, grasp the spatial position of the inside of the factory and the arrow body, and make advance predictions and positioning and debugging.
The number one hand was regularly separated around the arrow body. Accompanied by the commander's clear and loud command, the huge arrow body slowly rose with the hook , and everyone present observed the position of the arrow body intently. Time and space seem to freeze at this moment, and only the trumpeters who adjust their positions from time to time remind that important work is being carried out here.

dare to "cast arrows" on the platform, and you must be willing to "sharpen your sword" off the stage. The characteristics of rocket lifting work determine that each lifting training starts for two hours. During the training, the commander and every twitter must be in the position throughout the whole process and devote themselves to it.
walked into the training site of the hoisting team. The twelve twelfth players kept running, connecting, freeing, flipping and landing under the command of the commander. Trumpeter Shi Yangbo said: "We must not only be very clear about the process, but also focus on ensuring the safety of rocket products." Training is boring, but in order to ensure the safety of lifting work, none of the team members complained about being tired because they all have the same goal: to lift the Mengtian Experimental Cabin to successfully evacuate and complete the last "puzzle" of the China Space Station construction task with .

"Hear a huge arrow without distraction, and the force is tremendous." This is the work motto that everyone in the hoisting team remembers in their hearts, and it is also a true portrayal of their work. It is such a group of young men with an average age of less than 25 years old who shoulder the noble mission of "casting arrows" for the country. The task of the
space station construction phase is about to be completed, but they are always ready to welcome the next task with a progressive attitude and a perfect attitude.
