Vehicle was carrying canned Guinness. The front tyre failed and the driver lost control before going up the embankment and overturning alongside a crash barrier. The grab lorry was used to clear the load. The tractor unit was taken off the trailer and righted in the air before being placed alongside the rotator. Both rotators were then able to lift the trailer and right it, again in the air, before placing it away from the load and allowing a final clean up. At one time, there was a river of Guinness flowing beneath the rotator.
