What's the difference between snowmobiles, sledges and steel snowmobiles?

The differences between snowmobiles, sledges and steel snowmobiles are as follows.

The difference between snowmobiles and snowmobiles is sleigh. Steel-framed snowmobiles only have a base without a shell, and snowmobiles have a shell, which is more like a car. Sleds and steel snowmobiles have no steering and braking devices, while snowmobiles are equipped with steering and braking devices. Sled gets initial speed by swinging back and forth and raking ice, while snowmobile and steel snowmobile get initial speed by running to push the car body. Sled lying, snowmobile sitting, snowmobile lying.

In fact, these three projects have both similarities and their own characteristics.

First of all, all three projects are very fast, with the top speed exceeding 130 km/h, and secondly, all three projects are very dangerous and will "roll over" if they are not careful. Finally, they all require athletes to have the ability to obtain the maximum initial speed and the ability to flexibly control their limbs to maintain the balance of their bodies or instruments in order to adapt to the continuous improvement of speed. Therefore, in the choice of athletes, athletes who are "big and fast" are more popular.

The tracks of the three events are the same, all in the National Snowmobile Sled Center, and the destinations are the same. But the starting point is slightly different, in which snowmobiles and steel snowmobiles are the same, while men's snowmobiles have a higher starting point than snowmobiles and steel snowmobiles, but the starting distance is shorter, that is, the slope is steeper. Soon after the launch, snowmobiles, snowmobiles and steel snowmobiles used a track.
