(Winter Olympics asks "Ji") Was it cancelled due to excessive danger? The "return road" of the steel frame snowmobile
China News Service, Shijiazhuang, December 24. The long sleigh used by North American Indians to carry goods in winter is the prototype of a steel-framed snowmobile.
In 1892, the British Child Child used a sled mainly made of metal materials. This sled was officially named a steel framed snowmobile.
The steel frame snowmobile is also called the sledge.
Athletes need to bend down flat on the sled and slide in a prone position, with a maximum speed of 130-140 km/h.
The power of sled sliding comes from the thrust and gravity of the athlete, and the athlete relies on the movement of the body to control the direction.
The steel framed snowmobile has no steering gear and brake device, and the bottom is composed of a skeleton weighted by a lead block and two fixed tubular steel blades.
Due to the extremely fast speed and the head down, the danger is extremely high, and the steel-framed snowmobile has disappeared several times in the Winter Olympics.
After the International Sled and Snowmobile Federation was formally established in 1923, it was recommended to include the steel-framed snowmobile and snowmobile in the 1924 First Winter Olympics competition. However, due to the dangers, only the snowmobile project was finally accepted for inclusion. .
At the 2nd Winter Olympics in 1928, the steel-framed snowmobile was officially included in the competition, which was divided into one event for men and one for women.
Since then, the project was cancelled. It was not until the 5th Winter Olympics in 1948 20 years later that the men's steel-framed snowmobile project was again included in the competition, but it was cancelled at the subsequent Winter Olympics.
It wasn't until the 19th Winter Olympics in 2002 that the event reappeared, and women's events were added at the same time.
