Modern sports competition is not only a contest on the sports field of athletes, but also a high level of sports science and technology equipment with athletes, which is a competition of national science and technology level.
When people around the world turn their attention to the Beijing Winter Olympics, China's domestic brand ice and snow equipment has also been focused and concerned by the world. The domestic snow rollers, snow wax cars and other ice and snow sports equipment that debuted on the field integrated multiple elements such as intelligence, data analysis, green and low carbon, and became the highlight of the Games.
The Chinese team members had their own snow wax car
Technology empowers sports. When inspecting the preparations for the 2022 Winter Olympic and Paralympic Winter Games in Beijing, General Secretary Xi Jinping stressed that in today's world, the role of science and technology in competitive sports is becoming more and more prominent. To build a sports power, we must achieve a high level of sports science and technology self-reliance and self-reliance. It is necessary to integrate the strength of multidisciplinary and interdisciplinary disciplines, comprehensively promote technology research and development and technological transformation, and provide strong support for China's competitive sports to achieve greater breakthroughs. From bidding to preparation, "science and technology" has become a major background for the Beijing Winter Olympics. A series of new technologies and applications are being tested in the various testing work of the Winter Olympic Games, and the "Winter Olympics of Science and Technology" has entered reality from a vision.
Ice and snow sports have the characteristics of large range, fast speed, complex equipment, and multiple outdoor competitions, which put forward higher requirements for scientific and technological innovation. At the Winter Olympics, a number of products have achieved a breakthrough of zero.
In the past, China's ice and snow sports teams participated in competitions, and could only rent foreign vehicles or container-type board houses, and snow wax vehicles were blank in domestic equipment. The Beijing Winter Olympics Of China National Heavy Duty Truck Yellow River hydrogen fuel cell snow wax car, is China's first intelligent snow wax car with completely independent intellectual property rights, China National Heavy Duty Truck with science and technology to help the Winter Olympics, created a new height of "China's first, world-class, completely domestic production", to fill the gap of domestic snow wax car, from "do not know the snow wax car" to create "China's first snow wax car", it took less than a year.
Snow wax cart
It is understood that this snow wax car is more than 20 meters long, red and white van body snow wax car, which can be used by 6 waxers to wax the snowboard at the same time. Above the waxing table are inclined suction openings and lighting fixtures, and on the table are placed a variety of waxing tools used by waxers - snow wax, heating irons, scrapers, etc. In addition, in terms of power, it is also equipped with Weichai's 162kW hydrogen fuel cell system.
The first domestic snow wax vehicle involves new energy power, photovoltaic power generation, 5G communications, event live broadcasting, bionic light source and other fields of professional technology, with green environmental protection, high degree of intelligence, large body space and other characteristics, is the epitome of China's new breakthrough in winter sports equipment, is China's "intelligent manufacturing" of the new achievements.
Snow groomers came into being to break through technical barriers
Snow grooming is a large equipment necessary for the construction and maintenance of snow tracks, in the past, the world's production of snow grooming enterprises concentrated in Germany, Italy and other countries, almost monopolized the global high-end market.
In order to break down technical barriers, Hebei Xuanhua Construction Machinery Co., Ltd. (hereinafter referred to as Xuangong) has been committed to the research and development and application of domestic high-end snow groomers for many years, and successfully rolled off the line of the self-developed SG400 snow groomer in January 2018, breaking the monopoly of foreign technology and price in the field of snow groomers and filling the gap of similar domestic products.
Xuangong snow roller
On the slopes of Chongli Snow Field in Zhangjiakou, Hebei Province, you can see the figure of Xuangong snow roller working intensely. Among them, a bright blue body with a prominent "SG400" logo of the snow groomer passed, the slopes are uniform and seamless, very flat. "Its excellent performance makes us proud, because it is an SG400 high-end high-horsepower snow roller independently developed and produced by Hebei Xuangong, and before, there was no mature manufacturer in China to produce this type of machinery." Wen Xiaoxuan, the designer of the SG400 snow groomer, introduced that he and the R&D team look forward to the amazing performance of the snow groomer during the Winter Olympics.
It is understood that Hebei Xuangong has continued to optimize and upgrade the SG400 snow groomer, recently completed 109 improvement designs of 19 components, 16 key projects of technical research, and continued to make breakthroughs in optimizing the design and development of all components of the SG400 snow grooming vehicle. The project has achieved key technological breakthroughs, built relevant technical standards and evaluation and application specifications, accelerated the upgrading of snow grooming vehicles, and completely changed the status quo that China's large and medium-sized snow grooming vehicles are completely dependent on foreign imports.
For the first time, steel frame snowmobiles have been localized
In 2021, at the "China FAW Strategic Cooperation Signing Ceremony and Snowmobile Equipment Delivery Ceremony", China FAW and China Aerospace Science and Technology Group jointly delivered the domestic snowmobile - Hongqi Snowmobile to the Winter Sports Center of the General Administration of Sport. This delivery has achieved a breakthrough of "zero" for domestic snowmobiles, and also announced the end of the long history of Monopoly of Snowmobile Equipment in China by foreign brands.
China's snowmobile sports started late, the research and development foundation is weak, and the manufacture of snowmobile equipment has been monopolized by foreign countries due to its high technical content and complex manufacturing process. The advent of this domestic snowmobile has truly made the entire "lifeline" of the snowmobile, a high-tech sports equipment, firmly grasped in China's hands.
Steel frame snowmobile
Snowmobiles have been included in the competition since the first Winter Olympics. So far, the bobsleigh body is made of steel and high-tech materials such as fiberglass or carbon fiber, designed as an aerodynamic body complex with an average speed of around 100 km/h and a maximum of 160 km/h. The snowmobile is equipped with handles and two independent sets of glide steel blades at the bottom, and the helmsman drives the snowmobile through a pulley system controlled by two handles inside the snowmobile. The brakes are mounted at the rear of the snowmobile.
The domestic snowmobile condenses the top wisdom of China FAW and Aerospace Science and Technology, and the research and development process overcomes the key technologies of carbon fiber shell, chassis, brake, steering and other systems and vehicle design and manufacturing, and breaks through five problems such as welding durability analysis, fastener selection, structural strength optimization, carbon fiber optimization, and CAE analysis working conditions. Domestic snowmobiles have two types of snowmobiles, 2-person snowmobiles and 4-person snowmobiles, which will appear at the 2022 Beijing Winter Olympics and become the driving cars of the Chinese snowmobile national team, helping Chinese Winter Olympic athletes to ride the ice and snow and point to the champion.
Domestically produced specially developed all-terrain vehicles were unveiled
Ordnance Equipment Group actively serves the Beijing Winter Olympic Games and the Winter Paralympic Games, and resolutely provides high-quality vehicle and personnel support for the event with a strong sense of responsibility.

Install the tracks
The Winter Olympics and its surrounding areas are covered with deep snow, and when the vehicle transports the personnel and materials of the event, it is not only necessary to drive on the slippery road, but also to frequently face steep slopes and deep potholes, which puts forward very high requirements for the performance of the vehicle. From the company's test field to the Winter Olympic Games, after several trials and demonstrations, the "wheel and track combination" technology was finally successful.
High-quality equipment to create a green Winter Olympics
Adhering to the Winter Olympic concept of "green, open, shared and clean", the Beijing Winter Olympics will become the first Olympic event to truly achieve carbon neutrality. On January 13, the State Council's new office held a conference on green winter Olympics and sustainable development for the Beijing Winter Olympics and Paralympic Games, and Li Sen, director of the overall planning department of the Beijing Winter Olympic Organizing Committee, said that the Beijing Winter Olympics strictly implement low-carbon management and will fully achieve carbon neutrality through a series of measures. Among them, the construction of a low-carbon transportation system, energy-saving and clean energy vehicles accounted for more than 80% of the event vehicles.
Hydrogen fuel cell vehicles as a highlight of this Winter Olympics. As the backbone enterprises of the domestic commercial vehicle industry and the hydrogen fuel cell system industry, Yutong Group and SDIC Hydrogen Energy Company have carried out close communication since 2020, and the 100 hydrogen fuel cell buses jointly developed by the two sides will be used to serve Yanqing District and help the Beijing Winter Olympics.
Hydrogen fuel cell buses
As the backing of hydrogen energy vehicles, CIMC Hydrogen Energy Technology Co., Ltd. provided more than 30 hydrogen tube bundle containers and more than 10 50MPa hydrogen storage cylinder groups for the Beijing Winter Olympic and Paralympic Games, and recently delivered 70 megapascals of skid-mounted fully integrated hydrogen refueling station equipment, with a full range of multi-variety hydrogen energy boutique equipment to fully assist the Beijing Winter Olympics carbon neutrality commitment.
On this basis, PetroChina, state grid and Three Gorges Group have also sponsored carbon neutral products for the Beijing Winter Olympics, through which the Beijing Winter Olympics will be fully carbon neutral.
The ice and snow industry is constantly iteratively upgrading
The holding of the Beijing Winter Olympic Games and the Winter Paralympic Games will further heat up the ice and snow sports, and also promote the development and technological upgrading of china's ice and snow equipment localization.
