The Ferris wheel from which ABUCO fabricated the columns and the main axle is currently being built up by Dutch Wheels B.V in Chicago. The building progress is going well. The expectation is that the ferris wheel will be ready for use around the end of May 2016. This ferris wheel is greater than the ferris wheel which it replaces. When the construction is completed, this ferris wheel will be 60 meters high.
Below are some pictures of the construction of the ferris wheel.
