Fixed Ferris wheels are usually intended for permanent installation, as opposed to transportable wheels which are designed to be operated at multiple locations. Occasionally however, fixed wheels are also sometimes dismantled and relocated. Larger examples include the original Ferris Wheel, which operated at two sites in Chicago, Illinois, and a third in St. Louis, Missouri; &lt;a href="Technocosmos"&gt;Technocosmos/Technostar&lt;/a&gt;, which moved to Expoland, Osaka, after Expo '85, Tsukuba, Ibaraki, for which it was built, ended; and Cosmo Clock 21, which added onto its original height when erected for the second time at Minato Mirai 21, Yokohama, in 1999.
