The machine that carried the Space Shuttle to the launching pad moved at a snail-paced 3km/h (2 mph).

The Space Shuttle Crawler’s 2 mph top speed was only attainable when it was unloaded.  When loaded it can only travel at 1 mph.  At a weight of 2,721 tons, it is also the world’s largest self-powered land vehicle.
