When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. It took five years to design and manufacture and five years to assemble, with total cost reaching $100 million. In 1995, it was itself superseded by the slightly heavier Bagger 293 (14,200 tons). XCMG's XGC88000 Crawler Crane remains the largest self-propelled land vehicle in the world, since bucket-wheel excavators are powered by an external power source, and the Overburden Conveyor Bridge F60s hold the title of largest land vehicle of any type by physical dimensions.
