Abstract:
A free-fall tower for a roller coaster, the tower having an approximately vertical axis and comprising:a lower tower section and an upper tower section arranged for approximately vertical movement of a passenger unit from the lower tower section to the upper tower section and then from the upper tower section to the lower tower section, the lower tower section including at least two rail sections, and the upper tower section being configured to receive the passenger unit from one of the two rail sections of the lower tower section for movement to an elevated position, and then to direct the passenger unit for free-fall from the elevated position to the other one of the two rail sections of the lower tower section; wherein the upper tower section has at least one rail section for guided movement of the passenger unit to the elevated position, and the upper tower section is rotatable about the approximately vertical axis of the tower between at least two relatively rotated positions respectively aligning the rail section of the upper tower section with the two rail sections of the lower tower section, whereby the passenger unit can move from one of the two rail sections of the lower tower section to the rail section of the upper tower section when the upper tower section is in one of the two relatively rotated positions, and then the upper tower section can be rotated with passenger unit on the rail section thereof to the other one of the two relatively rotated positions for descending movement of the passenger unit to the other of the two rail sections of the lower tower section.
