Big Muskie. Big Muskie was a legend among machines while in operation. Also called Muskie and Ol Musky, the machine was a model 4250W BucryusErie dragline. It was the only model ever built, and took two years and some 200,000 hours to construct. When Muskie was built in 1969, it cost 25 million dollars. That's approximately 171 million today!

In the early 1960s, increased production was needed to meet rising demand for coal by Muskingum River Power Plant. The increased mining capability was achieved with Big Muskie, a BucyrusErie 4250W dragline. Huge by any standards, the 4250W was the largest walking dragline ever built. It also was the biggest machine ever to move on land.

hello, I worked for Amax Coal Co as a Chief Electrician, with the BE 3270 at Delta Mine. It is/was truly an amazing machine! It was powered by a single 25KV, 3ph power cable, which powered two 25kv/6900v subs, one on each side of the machine. There were 6 motor/generator sets, each with a 3,000 hp sync motor at 6,900vac driving dc generators.
