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.
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.
This giant machine is close to seven stories high and can move over 250,000 pounds of earth across 200 yards in less than 60 seconds. This simple and efficient dragline is perfect for coal mining. 4.) T 282B. The T 282B is one of the largestcapacity dump truck in the world offering a payload capacity of roughly 400 tons ...
The story: This 6400 carries a 16cubicyard bucket on a 160foot boom, and is seen at work uncovering anthracite in Pennsylvania. Having achieved great success with its sevenyard 4600 excavator, and listening to demands from its American coalstripping customers, introduced the 6400 dragline in 1977.
A coal mining company in Center commissioned a 31 million dragline Monday and is about six weeks from putting the massive coal miner to use. BNI Coal hosted the ceremony at its Center Mine. The machine that was previously operated by Mississippi Power Co. for six years is the world's newest 757 Page dragline.
Remember, this is the BE 1450 Dragline that was built at Ken Mine in 1964. It was a huge machine in that time frame. This dragline was operated at the mine for over twenty years. In 1985 this enormous Dragline was shut down at Ken Mine, loaded on a barge and shipped down river to Peabody Coal Company's, Gibraltar Mine.
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.
Armstrong Coal Company Page 752LR Walking Dragline #37 "Computer Room" ^^^This is a custom built room inside the Machine House of the dragline and it's the "Brains" of the machine. Everything is monitored from in here. Everything. Armstrong Coal Company Page 752 Walking Dragline The second dragline is just slightly smaller than the 752LR.
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 ...
To achieve the objectives, realtime studies were done in a large mechanized open cast coal mine of India, deploying large capacity draglines for the removal of overburden. ... Kumar A (2013) Analysis of resistive force formation against the bucket action of a dragline machine. In: Proceedings of the national seminar on Dragline Mining ...
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 ...
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 ...
Horizontal Tandem Operation. In the horizontal tandem operation (Fig. 1), both the draglines are deployed on the same bench for a fast rate of advance and coal exposure [13, 14].The cut width taken by the draglines will be wider depending upon the operating radius of the draglines [].The leading dragline is deployed on the highwall side and provides a key cut toward the highwall, and after ...
The immense dragline machine was churning along at full production until 1991, when power demands and other factors convinced the owners to shut down," the Roadside America says. ... "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.

India produces about 90% of Coal from opencast mining. Opencast mines deploy large number of state of the art Heavy Earth Moving Machines like Draglines, Bucket Wheel Excavators and Shovels and ...
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.
There were three of the giant machines at issue: The Tiger, The Mountaineer, and The GEM of three were then in the service of the Hanna Coal Company, which by 1970, had been strip mining in Ohio for decades and was then a division of the much larger Pittsburgh Consolidation Coal Company, later known as "Consol," itself then owned by Continental Oil.
The Big Muskie, a Model 4250W, was constructed by the BucyrusErie Company in 196669 for Central Ohio Coal after two years of design work. 1 3 The company chose the dragline excavator over a traditional shovel because it could strip 8,000 yards of overburden per hour to allow for the uncovering of highsulfur brown Ohio coal 185feet below ...
This 1,200ton machine walked, backward, at up to a blazing maximum speed of miles per hour. While most dragline excavators are dismantled after being retired, this one was saved by the ...
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.
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.
