The biggest dragline to ever work in Pennsylvania, the one and only Marion 8700! Built in 1965, this ole girl swings an 85 yard drag bucket on the end of a 300' boom and weighs just over 4,600 Tons! I spotted two more draglines in this pit. And four draglines in this pit. Lucibello Heavy Equipment Photography posted five photos as part of a ...
The Walking Mechanism on a preserved BucyrusErie 1150 dragline in the UK. The coal mining dragline known as Big Muskie, owned by the Central Ohio Coal Company (a division of American Electric Power), was the world's largest mobile earthmoving machine, weighing nearly 13,000 tonnes and standing nearly 22 stories tall.
Ursa Major in 2009. The Ursa Major (lit. Great Bear) at Black Thunder Coal Mine, Wyoming, is the largest dragline excavator currently in use in North America and the third largest ever built.

Although an old dragline can be an essential part of mining operations, the equipment is not without fault or maintenance needs. Bottom line is, draglines don't last forever. They are among miningclass machines with booms that reach hundreds of feet into the sky. The cost of dragline machines is somewhere between 50M and 100M. Some even ...
surface coal mining from shovel mining to dragline mining. Coal India Limited (CIL), now has standardized the draglines in two sizes, namely 10/70 and 24/96 for their mines. Most mines depend on the dragline 24 hours/day, 7 ... which the machine is named a Dragline. Thus greater skill is required to control the bucket.
Peabody is utilizing a single Bucyrus Erie 2570W Walking Dragline (Lot #1) named "Big Kate" to get to the coal at this surface mine. "Big Kate" is BIG, sporting a 100 cubic yard bucket and a 310 ft. boom. She's one of three BE 2570's in Indiana. The other two are up further north close to the new Bear Run Mine.
They were supposed to restore the land to its "approximate original contour." This mine was started in 1974 using the "shoot [explosions] and shove" technique. The dragline was introduced in 1984. The last coal shipments were in 2016. The dragline had been helping with mine reclamation.
Much of the credit went to Peabody's giant shovel, which could strip away 200 cubic yards of overburden in a single bite. "This shovel weighs as much as a Navy cruiser, stands 20 stories high, and ...

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!
Draglines remove dirt to expose coal and other minerals underneath. Some of the biggest machines can lift several hundred tons in a single scoop, and the bucket alone is about the size of a twocar garage. The machine house is 100 x 118 ft. with a 350 ft. boom and currently uses a 100 CY bucket. The PH 9020 has only been in operation since ...
Kim Fundingsland/MDN The massive dragline that removes earth above veins of lignite coal at the Falkirk Mine near Underwood operates 24 hours a day, seven days a week. It began operation in 1980.
A generation ago, now maybe two, the rolling hills of western Kentucky reverberated with the rumbles of many great mining machines. Similar to mechanical dinosaurs, these towering machines, some among the largest ever constructed, were emblematic of the scale and import of the area's healthy coal industry. From the mid1960s through the late ...
A coal mining car at Lackawanna Coal Mine in Scranton, Pennsylvania Coal miners exiting a winder cage at a mine near Richlands, Virginia in 1974 Surface coal mining in Wyoming, A coal mine in Frameries, Belgium. Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity.
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 Rich History of Big Brutus. Constructed in 1962 by the Bucyrus Erie company for the Pittsburg Midway Coal Mining Company, Big Brutus served as a testament to human ingenuity and hard work. This colossal machine operated for over a decade, dramatically increasing the efficiency of coal mining in the region before retiring in 1974.
Formed in 1992, HCRHP's focus is to provide a comfortable rest home for The Silver Spade, a BucyrusErie 1950B that was commissioned in 1965. Weighing 14 million pounds and standing 220 ft. tall while swinging a 105 cu. yd. bucket, it's the largest electric stripping shovel still doing the job it was designed to perform.
The "Big Muskie" was once the world's largest earth moving machine. Built in 1969 and dismantled in 1991, the Big Muskie could move 39 million pounds of earth and rock every hour, reaching coal seams 100150 feet down. Weighing nearly 12,000 tons, this dragline was 22 stories tall with a boom length of 310 feet.
Cat® draglines offer the lowest material removal cost per ton, consume less power and emit fewer greenhouse gases than other methods of overburden removal, making them the most productive and environmentally friendly excavators in the industry. The Cat® 8750 is our flagship model. It's the first dragline of any kind to be successfully equipped with AC IGBT drive systems — a superior ...
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.

The cost of overburden removal per cubic yard is lower with a shovel than with a dragline but the difference is ...
The Big Muskie, a model built by BucyrusErie of Milwaukee, went to work uncovering coal in May 1969, and this is the 50th anniversary of its startup. The 14,000ton machine with a 220 cubic yard bucket was retired in 1991. For those of us who grew up in East Central Ohio, large strip mining machines were not uncommon.
By Donna Schmidt, Field Editor. A recently restored Page 757 dragline sits on the assembly area at NA Coal's Cabot Marshall mine in Texas. After making the move from Wyoming and being fully restored with many upgrades, the new dragline, Carmen, began production in January. It is not every day that a dragline changes hands and moves from one ...

Draglines typically can offer a low cost waste removal mining method but are less flexible and have a higher capital cost. Truck/shovel fleets on the other hand are far more flexible with lower capital but generally higher unit costs. "The deployment of draglines and truck/shovel fleets can be varied so that competitiveness (lower costs) can ...
So that a wide area may be is mined in a succession of strips. Usually large tonnage reserves (especially coal) are mined in a continuous progression across the mining area with gradual changes in overburden thickness. The trend is to larger stripping machines and a walking dragline with a 170 m (220 yd.) bucket has been in service for ten years.
No one was injured at the Falkirk Mine, and the two employees aboard dragline 102, also known as Chief Ironsides, were able to exit it safely, according to David Straley, director of government and public affairs for North American Coal Corporation. Straley said the company expects to have the machine up and running within three to 10 days.
