Crawler, Cape Canaveral
Crawler seen from Launch Control Centre
The crawler carried the Saturn Five rockets of the Apollo program and the Space shuttles to the launch sites, keeping the load level as it climbed the hill up to the launch pad. Here is a view of a naked crawler (without the steel box that holds the rocket during launch) crawling towards the launch sites. We were told it was testing its new disc brakes. The view is from the launch control centre.
Crawler
It runs on a bed of rocks buried six feet in the ground.

You can see the new disk brakes at the end of the engines, with the callipers painted bright blue

I will post a few more pictures of the crawler when I have a minute.

My father, George Baron, helped design this. He was a mechanical engineer at Marion Power Shovel.
Well our company, American Warming & Ventilating, Toledo, Ohio – had the privilege of working on part of the crawlers cooling system for the atomic powerplant that ran the whole crawler from building the rocket (Saturn 5) to lunchpand. That was back in 1969-1969, I believe?
No atomic power plant in the crawlers – huge diesel engines driving generators
