The Big Muskie was a model 4250-W dragline and was the only one ever built by the Bucyrus-Erie company. [1] With a 220-cubic-yard (170 m 3) 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 ...
From 1985 onwards, all new machines carried the 'RB' name instead of 'Ruston-Bucyrus', and in 1987, a new mechanical/hydraulic powered 51–60 model developed from the 38-RB was offered for use as a crane or dragline excavator [1] In 1990, RB bought from its rival Priestman, the design and manufacturing rights to Priestman's Variable ...
Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288 [2] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. [3]
On average, all Baggers require a total output 16.56 MW (22,207 hp) of power to function with all-systems running. [5] [4] Their primary goal as BWEs, is in excavating lignite coal in Germany for processing to be turned into energy or 240,000 cubic metres of overburden daily. [16] [17] Currently, all Type SRs 8000s are in-service.
Their power consumption on order of several megawatts is so great [quantify] that they have a direct connection to the high-voltage grid at voltages of between 6.6 and 22 kV. A typical [ further explanation needed ] dragline weighing 4000 to 6000 tons, with a 55-cubic-metre bucket, can use up to 6 megawatts during normal digging operations.
Marion 6360, known as "the Captain", was a giant power shovel built by the Marion Power Shovel company. Completed and commissioned on October 15 1965, [1] it was one of the largest land vehicles ever built, [2] exceeded only by some dragline and bucket-wheel excavators.
A power shovel, also known as a motor shovel, stripping shovel, front shovel, mining shovel or rope shovel, [2] is a bucket-equipped machine usually powered by steam, diesel fuel, gasoline or electricity and used for digging and loading earth or fragmented rock and for mineral extraction.
