The crawler-transporter is an immense vehicle, adapted from earth-moving machinery, which carries the Space Shuttle, and previously the Saturn V, on a crawlerway from the Vertical Assembly Building to one or
other of launch pads 39A and 39B at Cape Canaveral.
The crawler-transporter is 40 meters long and 35 m wide, weighs 2,721 tons,
and contains two diesel generators that provide 5,600 hp for the electric
drive motor system. It moves on four double-tracked crawlers, with hydraulic
jacking pads on 27-m centers. Traveling at a mere 1.5 km/hr, it guzzles
fuel at the rate of one liter every 1.6 m (one gallon every 20 feet).
