In 1966, an exciting project started at the factories of the Bucyrus Erie Co. – the engineering and building of the components of what would be one of the world’s largest earthmoving machines ever built, “Big Muskie.” Central Ohio Coal Co. had chosen this immense machine because the mine property extended over 110,000 acres of hilly terrain and made the use of a dragline versus a shovel to be more profitable at the levels of earth the coal was located in. It also allowed the coal company to better carryout their reclamation plans.
The machine was so large it was necessary to ship the components to the coal mining customer in Ohio and erect the machine on site. It took 340 rail cars and 260 trucks to ship all of the components and 200,000 man hours to construct, but the machine finally went into production in 1969.
Weighing in at over 27,000,000 pounds, it stood nearly 22 stories high and had a 330-foot twin boom and a 220-cubic yard bucket the size of a 12-car garage.
In 1976, “Big Muskie” removed 8,000 yards of overburden for the coal company per operating hour. In its 22 years of service, it removed twice the amount of earth moved during the original construction of the Panama Canal.
Shut down in 1991, “Big Muskie” was finally dismantled for scrap in 1999. The only component saved was the bucket, which was later incorporated into a display about the machine and surface mining and reclamation in Miners Memorial Park in McConnelsville, Ohio.
It was electrically powered with 13,800 volts. [tractors]
The electricity cost tens of thousands of dollar an hour, and explains why the crew of five usually worked at night when power costs were cheaper.
[The video below says it stopped only for 30-min lunch breaks, maintenance, and Christmas Day.]
Giant draglines have long since been made obsolete, but dragline excavators are still very much in use. The largest available dragline on the market today is Joy Global’s P&H 9020XPC. The bucket has a capacity of (110yd³ to 160yd³.) Unlike the hydraulic engines and motors of years past, current draglines use digital AC controls.

moving the parts of BIG MUSKIE took a violent amount of brutal pulling and pushing power
David Lane In dragline terms, that is the 'tub', the base that the dragline sat and rotated on. The Muskie was the largest dragline ever built(if I remember correctly) Saw these pics many years ago on the old STRIPMINE.ORG. I grew up just northeast of her.

James Peeler Them 41-B Allis Chalmers were a brute of a machine!!
Eric S Manners I read when they rebuilt the tub, they used 30,000 lbs of welding rods!
Joseph Bonola 2 weeks work just greasing the roller path.

Visited this last spring in Ohio. Bucket from Big Musky.

James Butch Rainey Hard to imagine 220 cubic yards! Amazing every time I see it.
Mike Mccarley James Butch Rainey. I look back at my pictures of the Marion 8200's that I worked on in the 80's. And i thought an 85 yard bucket was big. Damn!

Here’s our car next to the bucket on Christmas Day of ‘98.

great bucket pic
This Facebook info is near the end of the notes so that hopefully the sidebar is empty and the "Original Size" images are readable.

6x D9 is pulling the bucket for big muskie.
Dennis Bertoncelj The bottom of that bucket gets hot.Matty Carey Dennis Bertoncelj try dragging it through rock with 12,000 horsepower 3 or 4 hundred thousand times.
They get a lot hotter. [The video below says it had up to 52,500hp.]Dennis Bertoncelj Matty Carey yeah ive burnsd my hand on a tooth or two.Dennis Bertoncelj Matty Carey the tub gets pretty hot on a long deadhead too

A "Big Muskie - 4250-W Bucyru-Erie" Album with 22 photos and the comment:
The Big Muskie was a model 4250-W Bucyrus-Erie dragline (the only one ever built). With a 220 cubic yards (170 m3) bucket, it was the largest single-bucket digging machine ever created and one of the world's largest mobile earth-moving machines alongside the Illinois-based Marion 6360 stripping shovel called The Captain and the German bucket wheel excavators of the Bagger 288 and Bagger 293 family. It cost $25 million in 1969, the equivalent of $157 million today adjusted for inflation. Its bucket could hold two Greyhound buses side by side. It took over 200,000 man hours to construct over a period of about two yearsA share of the Muskie album has some interesting comments including:
Robert Bann Machine was too big, too much down time, to much maintenance. COCC realized that 2 machines designed in the 120 yard range would have out preformed the Big Muskie.
David Kam Hudder Amazing engineering
