Took this little video of the Hong Kong Port yesterday. About $250 Billion worth of China's exports go through here, or over 12%. Probably about half of your consumer products come through here.
You can see the cranes that haul the containers. They can lift up to a couple thousand tons. There are 9 terminals(different areas around HK), and together have 92 cranes. I think this is terminal 9 which is the biggest.
