History The Crawler-Transporter is a tracked vehicle used to transport the Saturn V rocket, and now the Space Shuttle, from NASA's Vehicle Assembly Building to the launchpad on a Mobile Launcher Platform. The Crawler-Transporter, built by the Marion Power Shovel Co. at a cost of $14 million, was once the largest tracked vehicle in the world; it has since been surpassed by the Bagger 288 German excavator. It has eight tracks, two on each corner; each track has 57 shoes, and each shoe weighs approximately 900 kg (about one short ton). It measures 131 ft by 114 ft (40 m by 35 m); the height from ground level to the platform is adjustable from 20 to 26 ft (6 to 8 m). The transporter weighs 6 million pounds (2,700 t).
