Claim:
An overhead installation for transporting people, comprising two overhead carrying cables spaced apart from one another, extending in parallel manner on the same level, being stretched taut between two pillars to form a curved running track presenting a deformable sag, and a positively guided, servo-controlled vehicle comprising a passenger compartment, four rollers arranged in the form of a rectangle, with two rollers longitudinally spaced apart from one another running on one of the cables, and two rollers longitudinally spaced apart from one another running on the other cable, to support and guide the passenger compartment of the vehicle running on the curved track, and a connecting device without a hanger arm between the rollers and the passenger compartment to position the passenger compartment longitudinally and transversely, wherein the four rollers follow the height variations of the cable in space independently, during movement of the vehicle, said connecting device comprising an individual positive height-adjustable jack for each roller, and the vehicle comprising a central unit which controls the different individual jacks so as to compensate the height variations of the different rollers, imposed by the cables, during movement on the curved track.
