Whats the largest man made object that moves on dry land?

Answers:
Unless you're counting trains as one vehicle each, it appears that the largest land vehicle is the Bagger 288 excavator, weighing 13500 tons, FIVE TIMES the size of the NASA crawler-transporter (which was previously the largest tracked vehicle in the world).
