Big Muskie A Brief Summary
The Big Muskie was a 4250W walking dragline manufactured by Bucyrus-Erie Company at their South Milwaukee plant at a cost of twenty-five million dollars. At twenty-two stories high and an extended boom that was almost 1.5 times the length of a football field, it was the world's largest mobile land machine. The dragline used more electrical power than a city of 100,000 people. It was capable of moving thirty-nine million pounds of earth and rock every hour.

The Big Muskie worked in the Ohio Power Company's Muskingum mine in eastern Ohio from 1969 to 1991. During that time, it removed 608,000,000 cubic yards of overburden -- twice the earth moved during the construction of the Panama Canal. This work uncovered over 20,000,000 tons of clean coal. It was parked on 01 March 1991 due to a depression in the market for coal. By the end of the decade environmental laws demanded the reclamation of the mining areas and the removal of all equipment. In 1999 it was dismantled and the bucket put on permanent display at Miners Memorial Park in Noble County, Ohio.
