Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288[2] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine.
When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons.[3] It took five years to design and manufacture and five years to assemble, with total cost reaching $100 million.[4] In 1995, it was itself superseded by the slightly heavier Bagger 293 (14,200 tons).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.
Like its siblings, the Bagger 288 require a disproportionately small number of people to operate, at just five total.[1] Whilst Bagger 288 is considered a "sibling vehicle" with Bagger 293, it is unclear if 288 receives the same moniker as 293's Type SRs 8000 by TAKRAF.[5]
