Passengers have been trapped on the Melbourne Star Observation Wheel at Docklands for over an hour on Saturday night.

The wheel was halted at 6pm on Saturday after one of the motors stopped working, with some passengers forced to use emergency urinals supplied in packs on board the ride.

Guests were able to access other provisions such as bottled water and jellybeans while suspended in the air, some at a height of 120 metres.

There were 95 people on board at the time and all exited the ride safely just after 7pm.

Joe Salvati told The Age he was on the ride with four kids, aged one to seven, and three other adults when it stopped.
