Passengers on a roller coaster were left stranded in mid-air after an operator stopped the ride in southern China.

Video filmed in the city of Nanchang in Jiangxi Province on May 2 shows 18 passengers stranded on the ride which stopped more than 70 metres in the air.

In another clip, tourists were seen walking down the track slowly.

A tourist said they were stranded in the air for more than 10 minutes and his legs were weak after walking down from more than 70-metre-high track.

According to local reports, an operator spotted the panel of the equipment was abnormal and stopped it to ensure the tourists' safety.

After checking, it was the system protection caused by the voltage fluctuation of the equipment operation panel, which was an emergency protection action.

For safety reasons, the operation of the roller coaster has been suspended and it will be reopened after the subsequent system maintenance.

5月2日14时2分，南昌融创乐园“云霄飞车”设备运行时，突发故障报警，设备停止在提升段，共有18名游客滞留，现场无游客受伤。
据游客回应称，等到救援时候已经有十几分钟，自己从70多米高空走下来的时候腿已经软了。
据了解，经初步排查，本次设备突发停止，原因为设备在运行中，操作员发现设备面板异常，为了保障游客安全，第一时间执行应急处置。后经排查，系设备操作面板电压波动造成的系统保护，属于设备自身的应急保护动作。目前出于安全考虑，设备已暂停运营，待后续进行系统维护后再进行开放。（视频由江西台提供）
