Yes, Reedy Creek Emergency Services has a platform truck they use for Monorail evacuations. I would guess they can use it for the gondolas as well. I'd assume they set them to a similar height to the Monorail beam so they can use the same truck.
When it comes down to it, like the Monorail an evacuation like that would be EXTREMELY rare with most of the evacuations being performed by just emptying vehicles into the nearest station as quickly as possible.
