Security inspection can take 5-10 minutes as a lot of people don't familiar with the procedures.
And please add at least another 20 mins or so to clear immigration after that when travelling during peak periods. Then take escalator down and you can see the buggies. If its there, you can just hop on for HK$60. If not and you have to wait, its probably easier to take the trains.
