Made in Ningbo: Key Base Components of the Beijing 2022 Winter Olympics Cauldron
Beijing 2022 Winter Olympics Cauldron, Xinhua
One highly anticipated part of the Beijing Winter Olympic Games opening ceremony – lighting of the Olympic flame – was unveiled as the two torchbearers placed the hand-held torch inside a giant snowflake-shaped cauldron. Rather than an inferno, there was only “micro-fire” unprecedentedly coming from a single torch.
“This time the last two torchbearers didn’t light up any new larger flames and the torch was directly set within the cauldron. Over the following month, it will burn in a low fire, conveying the low-carbon and environment-friendly concept."
“Like it or not, our design of the Olympic cauldron delivers a distinct idea: the cauldron represents the whole world, the cauldron ignition addresses an eco-friendly Olympics. This will become an iconic moment in the over 100-year history of the Olympic Games.”
“Almost all the previous designs of the Olympic cauldron only symbolized the cultures and identities of the host countries themselves. This snowflake-shaped cauldron however comprises smaller snowflakes bearing participating countries’ names. It has never been thought of in the past century.” The chief director Zhang Yimou introduced.
It is noted that the core ground base system of this Winter Olympics cauldron was designed and made by a Ningbo manufacturer, Zhejiang Dafeng Industry Co., Ltd.
而本届冬奥会主火炬地面核心装置系统，正是由来自宁波的浙江大丰实业股份有限公司设计打造的。
The system is composed of three major parts: the LED baseplate, auxiliary flipping lifts for the cauldron, and stair lifts.
主火炬地面装置系统由三部分构成：LED底盘、主火炬辅助翻转提升装置和台阶踏步升降装置。
The design of the Olympic cauldron pursued the theme of green and sustainable development. Clean hydrogen energy is used to support the flame, withstanding extremely cold weather and force-10 winds. Also, the core ground base system is made with eco-friendly materials and processes. The sub-system of flipping lifts include four sets of huge and sophisticated rack structures. With Dafeng's unique control system, the 9-meter-long racks can be lifted/lowered at different heights and rotated at different angles to complete complex curvilinear movements. Accordingly, the Olympic cauldron is intelligently raised 8 meters high and further sent into the sky. It is an unprecedented initiative.
The stair lifts are designed with an ingenious flipping compensator, so that the 24 steps (symbolizing the Chinese 24 solar terms) can always automatically keep at the same level vertically and horizontally. Even if the stairs are in motion, the torchbearers can ascend steadily.
The floor of the Bird’s Nest (aka. National Stadium) is made up of large LED screens and is unable to bear large and heavy objects, while the core ground base system must be installed in the steel frame of the lifting platform at the center of the Stadium, posing a major challenge.
Dafeng innovatively used a 260-ton crane with a hoisting span of over 60 meters in diameter. Its creative construction plan of hoisting a single piece of core ground equipment into the central lifting platform for splicing and installation at the Bird's Nest’s channel finally earned credit from the Organizing Committee, the supervision teams and experts.
At the Games, Dafeng has also been responsible for supplying 75% of the spectator seats in the venues. In terms of cold resistance and flame retardancy, raw materials of these durable seats have reached an international advanced level. Moreover, the seats are recyclable and pollution-free after being crushed.
