A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Dragline fall into two board categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site. Most crawlers cranes, with an added winch drum on the front, can act as a dragline.
The Krupp Bucket Wheel Excavator was built in 1962 at a cost of $6,000,000. It was 156 feet tall and 468 feet long. It operated at the Northern Coal Mine near Braidwood, Illinois until 1972, then it was dismantled and sent to the River King Mine near Linzburg, Illinois.
Feb 28, 2009· Dragline excavation systems are heavy equipment used in civil engineering and surface mining.In civil engineering the smaller types are used for road and port construction. The larger types are used in strip-mining operations to move overburden above coal, and for tar-sand mining.Draglines are amongst the largest mobile equipment (not water-borne), and weigh in the vicinity of 2000 metric ...
shovels replaced draglines as the primary strip mine excavator. But in the 1960's, draglines with increased size and power were again recognized as major' excavating tools. In 1963, a Bucyrus-Erie 1450-W dragline vas obtained by the Peabody Coal Company for strip mining at the Paradise Mine. This drag'line had a 250-foot boom
Jun 28, 2021· For large mining operations a bigger, heavier dragline excavator is needed. This type of equipment must be built onsite. It would cost too much to transport. These huge dragline excavators are meant to stay in place – and in service – for decades. Onsite dragline excavators are typically used in coal and oil sands strip mining.

In an Indian study for a large dragline operated surface coal mine, a 40% gain in OE in terms of mining rate (m3/hr) resulted in a gain in EE with an annual reduction of GHG, TSP, and PM10 ...
Dec 03, 2018· In an open cut mine, bulk dozer push can be one of the most cost-effective methods of moving overburden. Under the right application, the unit cost of dozer push sits somewhere between a dragline and truck/shovel excavation. So, if geotechnical conditions are favourable and the dozer fleet is sufficient, dozer push should be considered to replace some of the truck/shovel prime.
Draglines are the most expensive piece of excavating equipment at the mine site and it is important that they are operated safely, efficiently and economically. Draglines are versatile and provide a low cost mining method. In order to achieve high

Draglines in Mining. A large dragline system used in the open pit mining industry costs approximately US$50–100 million. A typical bucket has a volume ranging from 40 to 80 cubic yards (30 to 60 cubic metres), though extremely large buckets have ranged up to 168 cubic metres (5,900 cu ft).
Contour mining is reserved almost exclusively for removing the thin coal beds of the Appalachian region. In area mining, removal of overburden is accomplished with large draglines, stripping shovels, or bucket wheel excavators (BWEs). These machines excavate and deposit material in one continuous operation. The same function can be accomplished,

Open-pit mining. Some 53% of South Africa's coal is produced from surface mining, via open-cast or open-pit mines. This is because the coal is less than 60 metres below the surface. Open-pit mines use draglines, as well as truck and shovel operations to extract coal. A dragline excavator uses a dragline to pull a bucket by a wire cable.
Nov 30, 2016· Despite their limitations, and their extremely high capital cost, draglines remain popular with many mines, due to their reliability, and extremely low waste removal cost.
