The Big Muskie was a model 4250-W dragline and was the only one ever built by the Bucyrus-Erie. This Mammoth Dragline became the largest dragline in the World! (A record that still stands). This massive machine weighs in at a whooping 27 MILLION pounds! It spent 22 years in Ohio removing overburden from the vast coalfields. it removed over 608,000,000 cubic yards of dirt which twice the amount of dirt removed to build the Panama Canal!
