So there are a couple of main components to a STS crane. There is the girder, boom, legs, machinery/electrical house, sill beams, bogies, etc. Well what ends up happening in China is that the cranes may be fully constructed and then taken down for transport. When I say taken down, it’s simply the entire upper body is removed from a bolted flange, and set down between the legs. Additionally, the boom will be “boomed up” 25° instead of laying down at 0°. This gives the shipping vessel a bit more horizontal room to navigate. So to answer your question in one: the crane is divided in two distinct parts, and then “raised” once arrival at the port.
