I'm guessing they use a man lift like construction companies have. All they need to do is have one near by. The can be driven just about anywhere and the basket can lift up high. I saw some at job sites that can go up nearly 100ft! They would just have to take two people down at a time since the maximum weight is about 500lbs. I beleve I saw one at Mind Eraser at SFNE this year under the lift.
