"Retired space shuttles are being readied for museums, but there's one piece of equipment at the Kennedy Space Center that dates back to before the moon landing and it's not going anywhere. NASA's giant crawler transporter is the only machine with enough muscle to move Apollo rockets and space shuttles out to the launch pad, and after nearly 50 years on the job the agency's decided there's still no better way to transport heavy loads. It's about as wide as a six lane highway, higher than a two story building, with huge caterpillar treads at each of its four corners. ... Crawler two is being upgraded from its current lifting capacity of 12 million pounds — the combined weight of the shuttle and mobile launcher — to 18 million pounds, for NASA’s new heavy lift rocket."
