The Big Muskie was the World’s Largest Dragline and one of the seven engineering wonders of the world! The machine has been featured on the History Channel. The Bucket weighs 460,000 pounds empty and when loaded carried an additional 640,000 pounds. It’s volume is equal to that of a 12 car garage.

The Big Muskie was a model 4250-W Bucyrus-Erie dragline (the only one ever built). With a 220 cubic yard bucket, she was the largest single-bucket digging machine ever created.

In her working lifetime, the Big Muskie removed over 608,000,000 cubic yards of overburden (twice the earth moved during the construction of the Panama Canal), uncovering over 20,000,000 tons of clean coal. She cost $25 million in 1969.
