Maailma suurim ja kuulsaim draglain - "Big Muskie":
Big Muskie was a coal mining Bucyrus-Erie dragline owned by the Central Ohio Coal Company (formerly a division of American Electric Power), weighing nearly 13,000 metric tons (13,000 long tons; 14,000 short tons) and standing nearly 22 stories tall. It operated in the U.S. state of Ohio from 1969 to 1991. Big Muskie was the world's largest dragline, and one of the world's largest mobile earth-moving machines after Marion Power Shovel built the 6360 stripping shovel called The Captain at the Captain mine in Illinois and the German bucket wheel excavators of the Bagger 288 and Bagger 293 family.
Big Muskie cost $25 million in 1969, the equivalent of $150 million today adjusted for inflation. Big Muskie removed more than 608,000,000 cubic yards (465,000,000 m3) of overburden, twice the amount of earth moved during the construction of thePanama Canal, uncovering over 20,000,000 metric tons (20,000,000 short tons) of coal. It was 151.5 feet wide, 222.5 feet tall, and 487.5 feet long (46.2 by 67.8 m by 148.6 m) with the boom down. Its bucket could hold two Greyhound buses side by side. It took over 200,000 man hours to construct over a period of about two years.
Big Muskie was powered by electricity supplied at 13,800 volts via a trailing cable, which had its own transporter/coiling units to move it. The electricity powered the main drives, eighteen 1,000 horsepower (750 kW) and ten 625 horsepower (466 kW) DCelectric motors. Some systems in Big Muskie were electro-hydraulic, but the main drives were all electric. Big Muskie used the equivalent of the power for 27,500 homes. The machine had a crew of 5, and worked around the clock.
Big Muskie was dismantled in 1999, despite calls that it be preserved as a museum. Its bucket was relocated to a newly constructed Miners Memorial Park in Morgan County at .
