  • Bagger 288 Wikipedia

    The Bagger 288 was built for the job of removing overburden before coal mining at the Hambach surface mine in Germany. It can excavate 240,000 tons of coal or 240,000 cubic metres of overburden daily the equivalent of a soccer field dug to 30 m (98 ft) deep. The coal produced in one day fills 2400 coal wagons. The excavator is up to 220 m (721 ft) long (slightly shorter than Baggers 287 and 293) and approximately 96 m (315 feet) high. The Bagger's operation requires 16.56 megawatts of externally supplied electricity
