Dafang ダブルガーダー天井クレーンが Zhuque-2 の打ち上げ成功を支援

At 9:00 a.m. Beijing time on July 12, 2023, the Zhuque-2 was launched from the Jiuquan Satellite Launch Center in China, completing its mission in accordance with the established procedures, and the launch mission was a complete success. It was officially announced to the world that the world’s first liquid-oxygen-methane rocket had “flown to the sky” and successfully entered orbit.

今回の打ち上げミッションでは、打ち上げ現場では大方重機が開発・製造した中国製の新型ダブルガーダークレーンが数台使用され、ロケットの移送と吊り上げの要となるとともに、工場内でのロケットのハンドリング、移送、旋回、検査、試験、燃料補給を高精度で完了した。

Zhuque-2 liquid oxygen methane carrier rocket is a two-stage configuration, with a diameter of 3.35 meters, a height of 49.5 meters, a takeoff weight of 219 tons, and a takeoff thrust of 268 tons, making it the world’s first liquid oxygen methane rocket to successfully enter orbit.

A tiny lapse can lead to a huge mistake, any process of rocket launching has extremely high requirements for precision, and a slight mistake in each link will lead to launch failure, therefore, it has very high requirements for the crane’s precision, angle and micro-motion in the process of rocket lifting.

The new Chinese double girder crane provided by our company is equipped with self-developed electrical anti-sway, automatic positioning and micro-motion operation control system, which can reduce the amplitude of the sway by 95%, with a control precision of 2 millimeters, and a precision of 1 millimeter of the control micro-motion, which greatly improves the stability and precision in the process of the rocket lifting, and provides “Made in DaFang” equipment support for the flight of Zhuque-2.

Electrical anti-swaying, automatic positioning, micro-motion operation control technology, through the simulation of the laws of motion, the design of mathematical models, etc., the use of computers to control the operation of key components, so that the crane lifting the heavy loads “steady as Mt Tai”, and accurately achieve the operational intent.
At present, Dafang has established good cooperation with the four major satellite launch centers in China, and has successively helped Shenzhou series spacecrafts, Tiangong series space labs, Chang’e series lunar probes, and Long March series carrier rockets to fly successfully in the sky.

国の航空宇宙産業のために我々の役割を果たすことができることは、我々一人一人にとって非常に誇りであり、誇らしいことです。我々の揚力装置がロケットと同じフレームで撮影されることは、我々一人一人にとってこの上ない栄誉です。

Space exploration is never-ending, and the journey of dreaming is a long way to go. As a firm supporter of the national space industry, in the future, Dafang Heavy Machinery will continue to uphold the original spirit of industrial service to the country, highlight the power of China’s manufacturing in the new era, and contribute to the realization of the great dream of building a strong spacefaring nation, so that the Chinese people’s footsteps to explore the space are more stable and farther away.
