Evolution
Premiering at Munich Oktoberfest in 1992, constructed by Nauta Bussink & Bailey of Holland, Evolution remains one of the largest rides ever to be transported. Weighing a massive 300+ tonnes, 33 metres (113ft) high and wheel diameter of 15 metres (45ft), it earned a Guinness World Record for the largest inverting carousel structure ever built.
Evolution (also known as Imperator) consists of a giant arm bearing a rotating wheel holding 16 four-person gondolas on one end, and a set of 10-tonne counterweights at the other. With riders facing outwards, Evolution’s movement involves the freely suspended gondolas move upwards and outwards as the wheel turns. With this happening, the arm slowly turns 180° exposing the riders to strong g-forces before both movements usually stop, suspending the riders in an upright, inward facing position 33 metres off the ground. After a few minutes, rotation of the wheel and arm recommences to complete one 360° circuit before the ride cycle finishes.
| Only 3 units were ever made by Bussink & Bailey | |
|---|---|
| USA, Excalibur at Six Flags St Louis (ex-portable from Europe) | |
| Germany, Imperator, travelling German fairs again after being in storage for some years | |
| Japan, ex-Kure Portopialand (park version) currently in storage after the park closed in 2005 |
With the arm alone weighing 160 tonnes, Evolution travels Europe on 16 trailers (most classed as heavy over-size loads).
More common is Fabbri’s Evolution, manufactured under license by Bussink’s design. At 21 metres (68ft) it’s considerably smaller, portable on two trailers and accommodates 40 riders in 10 cars. Unlike Bussink’s design, the gondolas are not suspended freely with 360° mounts but are controlled by pneumatic cylinders at the operator’s discretion.
There are at least 3 Fabbri units in USA and 6 in Europe, both portable and park design.

Cman, you are confusing the Evolution with maXair, which is a Huss Giant Frisbee (awesome ride, btw).
I rode the one at Six Flags St. Louis (Excalibur) this year and it was quite an interesting ride. It spun a little faster than I liked but the ride experience was great. Like the fact that you didn’t go upside down though I think I would have liked the arm to do two revolutions.
