Fairground ride, safety system, method for operating a fairground ride, and method for recovering a car in a fairground ride

Abstract

An illustrated track section 2 of an inventive fairground ride 1 has a primary transport system 4 (lift) with a first conveyor chain 5, first chain wheels 6, and a first drive 7 for driving the first conveyor chain 5. The car 3 is transported by means of a first dog 8, which engages with the conveyor chain 5. In addition to the primary transport system 4, the fairground ride 1 has a secondary transport system 9. The secondary transport system 9 is arranged parallel to the primary transport system 4 and has redundant elements, namely a second conveyor chain 10 , second chain wheels 11, a second drive 12, and a dog 13 attached to the second car. Should the first transport system 4 fail, the second dog 13 can take on the full load of the car 3 and transport the car 3 further.
