摘要

The roller coaster has a carriage (4) and a track (2) which describes a curve along a section (18) and has a first end point (25), top point (24) and second end point (26) in the vertical plane. A drive unit moves the carriage along the track and the track is axis symmetrical and has a parabolic section. At the beginning of the end point of the curves section of the track an entrance acceleration occurs so that the rider feels no effects of gravity. A cabin (6) protects the rider and prevents sight with the outside world, and the rider can move freely in the cabin.
