Twenty theme park visitors had to be rescued after a roller coaster broke down 100ft off the ground.<br /><br />The "Gravity Max" ride at the Taichung Libao Paradise attraction had technical problems and stopped mid-ride on July 12.<br /><br />Terrified guests were left stranded and dangling precariously in the air while screaming ''it's stuck''. <br /><br />Park director Wang Yung-hao said the ride's safety sensors went haywire and accidentally turned off an electronic switch.<br /><br />He said: "As part of standard operating procedure, passengers are notified that the ride could come to a sudden stop if a safety mechanism is triggered, in which case it will be switched to manual mode and they will be escorted off the ride."<br /><br />Officials said the movable section of the ride - which claims to be the world's only tilt roller coaster - normally flips from horizontal to vertical when the carriage reaches the top then free falls straight down. <br /><br />However, this time the ride became stuck midway before completely switching to vertical mode.<br /><br />Staff switched to manual mode and placed the carriage into a horizontal position. All 20 rider passengers were safely removed via an emergency passage by park staff. There were no injuries reported from ride failure.<br /><br />Meanwhile, Taichung Urban Development Bureau said they regularly do inspection and spot checks of the rides in the park.<br /><br />It said: "The park has promised us that it would cooperate with the Tourism Bureau on an on-site inspection to evaluate the maintenance status of the equipment."
