Big Muskie was a coal mining Bucyrus-Erie dragline owned by the Central Ohio Coal Company (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 worlds largest Dragline and was the world's second largest mobile earth-moving machine after the Marion built 6360 stripping shovel called The Captain at the Captain mine in Illinois.

Big Muskie cost $25 million in 1969, which is $208 million today adjusted for inflation.[1] Big Muskie removed over 608,000,000 cubic yards (465,000,000 m3) of overburden, which is twice as much earth as was moved during the construction of the Panama Canal, uncovering over 20,000,000 tonnes (2.0×1010 kg) of coal. It was 151.5 feet (46.2 m) wide, 222.5 feet (67.8 m) in height, and 487.5 feet (148.6 m) in length with the boom down. Its bucket could carry 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 an electricity supplied at 13,800 volts via a trailing cable, which had its own transporter/coiling units to move it. The electric power was used to drive Eighteen 1,000 horsepower (750 kW) DC electric motors and ten 625 horsepower (466 kW) ones, instead of using a Diesel engine and hydraulic drive system that is more common today ( some systemes were electro hydraulic, but the main drives were all electric motor driven).[2] Big Muskie used the equivalent of the power for 27,500 homes. The machine took a crew of 5 to operate it (drive), and worked round the clock..

Big Muskie was dismantled in 1999, despite calls that it be preserved as a museum. Its bucket, however, remains at the site for educational purposes, and as a tourist attraction at 39.70 N, -81.73 W.

10,000 acres (16 sq mi; 40 km2) of the land stripped by Big Muskie were reclaimed and turned into a wildlife park called The Wilds, which opened in 1994. It is home to numerous species of African, Asian, and North American fauna.[1]
