1928 Winter Olympics, the snowmobile project with steel frame became an official competition for the first time. The snowmobile project with steel frame once competed in the 1928 Olympic Games in St Moritz, Switzerland, and was divided into one competition for men and one for women. It was not until 20 years later that St. Moritz hosted the Winter Olympics again and included steel snowmobiles in the competition.

However, the steel snowmobile project was cancelled after the 1948 Winter Olympics because of the high risk, which interrupted the history of the Olympic Games. It was not until the Winter Olympics in Salt Lake City in 2002 that it became the Winter Olympics again. In the first two competitions, the women's team only joined the men's team and the Salt Lake City Winter Olympics.

Rules of steel frame snowmobile competition.

The track used in the steel snowmobile competition is the same as the sled, but the difference is the sled and sliding posture. Sleigh is a player lying on his back, with his feet in front and back, while steel snowmobiles are the opposite. The player leans back on the snowmobile with his head toward his front foot.

When starting, the contestants line up at the starting point and start in the starting order. After the starting signal light is on, the competitor must complete the starting action within 30 seconds. When starting, the skater must push the snowmobile forward, get on the snowmobile quickly after accelerating and finish the race. The starting action must be announced by the skater himself. It is stipulated that the snowmobile with steel frame can only be carried on the stomach, and it is allowed to slide the belly to stick to the snowmobile. It is allowed to put down the snowmobile halfway, but when crossing the finish line, the contestants must finish the race on the snowmobile.
