Ferris wheel installation comprising a guide structure for gondolas having sliding ball joints

A Ferris wheel installation comprising:

• a wheel rim structure which is rotatable about a horizontal axis of revolution, and at least one gondola which is connected to the wheel rim structure by a guide structure comprising a bearing which defines an axis of rotation of the bearing, the bearing comprising at least two opposing raceways which are guided, relative to one another, so as to rotate about the axis of rotation of the bearing, a first of the two raceways being rigidly connected to the gondola, and a second of the two raceways being rigidly connected to a support, wherein the support is connected to the wheel rim structure by two sliding ball joints, each of which provides three degrees of rotational freedom and one degree of translational freedom along a slide axis, the slide axes of the two sliding ball joints being parallel to one another and remote from one another.
