Big Muskie, Walking dragline excavator in Morgan County, Ohio, United States.
The Big Muskie machine measured 22 stories tall and operated with a 220-cubic-yard bucket capable of holding two full-size buses side by side.
From 1969 to 1991, this Bucyrus-Erie model 4250-W dragline removed over 608 million cubic yards of earth, surpassing twice the volume of the Panama Canal construction.
The remaining bucket now stands at Miners' Memorial Park in Ohio, serving as a testament to the industrial heritage of coal mining in the southeastern region.
The excavator required electrical power equivalent to 27,500 homes and moved at a speed of 0.1 miles per hour using hydraulic walking feet.
Construction of this single-model dragline demanded 200,000 work hours over two years and cost 25 million dollars in 1969.
