You might think the crawler-transporter is the whole thing carrying the shuttle, but it isn't. There's the Mobile Launch Platform (MLP) that the CT picks up, and then the shuttle stack lies on top of the MLP.
The 2nd image shows just the CT, w ppl for scale.

Just a neat pic where you can see indentations in the dirt from the crawler-transporter's treads. Those vehicles (there are two of them) are hefty, weighing 2,721 metric tons each.
