Basically, it was a PR stunt like the following photo.

They need to park a pickup truck or something next to one of those crawler tracks for scale. But judging from the cab and handrails, those tracks are huge. Specifically, I don't think one will fit on a flatbed trailer. I wonder how they disassemble the base base unit for transport to a new work site.
