On the morning of June 5, the Long March 2F Yao-14 carrier rocket carrying the Shenzhou 14 manned spacecraft was successfully launched from the Jiuquan Satellite Launch Center. It is worth mentioning that Weihua Group, located in Changyuan City, Xinxiang, once again relied on its world's first crane anti-sway technology to successfully provide high-precision hoisting and transfer protection for the rocket.
It is reported that the Chang 2F Yao 14 carrier rocket deployed this time has a total length of 58.4 meters and a diameter of 3.35 meters. It is bundled with 4 boosters and has a take-off weight of about 480 tons. It can send the 8-ton Shenzhou spacecraft into the low-Earth orbit of the Chinese Space Station. Assembling and transporting such a big thing to ensure that it can go to the launch tower smoothly is not an "easy task". This requires similarly large and strong "muscular" lifting equipment.
In this launch mission, multiple lifting equipment produced by Weihua Group undertook the key aspects of rocket transfer and hoisting. "A heavy weight is a light weight" and the rocket was transported, turned over, inspected and tested in the factory with high precision.
Although the crane's "hands and feet" are thick, their lifting accuracy has reached an astonishing 2 mm. The secret is that they have a sensitive "brain" that can thread needles and threads - equipped with Weihua's independently developed anti-sway technology, which can reduce the amplitude of swing by 95% and improve the stability and accuracy during rocket lifting.
It is reported that this technology is the first of its kind in the world and has filled the technical gap in this field. It has now successfully served the four major satellite launch bases in China, helping the Shenzhou series spacecraft, Tiangong series space laboratories, Chang'e series lunar probes, Long March series launch vehicles, Mozi, and Shijian-13 satellites to successfully fly into space.
Weihua Group is located in Changyuan City, the "Famous City of Hoisting Machinery in China". It is one of the first batch of national technological innovation demonstration enterprises in the country. It has 33 national and provincial R&D platforms, including nationally recognized enterprise technology centers and national and local joint engineering research centers, and has the largest scientific research team in the industry with more than 1,000 people.
The company’s annual expenditure on technological research and development accounts for about 4%-6% of total sales that year, and it will exceed 600 million yuan in 2021 alone. Weihua Group has obtained more than 1,000 authorized patents, ranking first in the domestic industry; it has presided over or participated in the formulation (revision) of 115 international, national, industry standards, and local standards.
Against the background of the impact of the COVID-19 epidemic and the sluggish manufacturing industry, Weihua Group has achieved "upturn against the trend" - the average annual sales revenue growth rate has remained above 30%, and it has continued to be the "Manufacturing Single Champion Demonstration Enterprise", becoming the largest industrial crane manufacturer in the country and the second largest industrial crane manufacturer in the world.
