Type SRs 8000 bucket-wheel excavator
Family of Bucket wheel excavators
From Wikipedia, the free encyclopedia
The Type SRs 8000 or less commonly known as the SRs 8000,[1] is a family of bucket-wheel excavators known for being one of the largest land vehicles in history, with Bagger 293 being the largest of the series.[2] SRs 8000 series bucket-wheel excavators are famously used in the Hambach surface mine.[3]
Specifications
All members of the Type SRs 8000 weigh over 7,000 tons at minimum. The smallest and oldest of the family, Bagger 281 (built in 1958[4][5]) weighs over 7,800 tons, although the average weight range is around 13,000 tons.[6] Likewise, all members reach lengths of over 200 meters and require a small crew of five.[7][2] Such a size would mean that these vehicles would have its own on-board toiletry and kitchenette rooms.[8]
As BWEs, the Type SRs 8000s are all externally powered by a nearby coal production plant with an internal 6,413 kW (8,600 hp) powered electric motor to keep the machine operating smoothly. On average, all Baggers require a total output 16.56 MW (22,207 hp) of power to function with all-systems running.[9][10] 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.[11][12]
Currently, all Type SRs 8000s are in-service. They are Bagger 281 (1958), Bagger 285 (1975), Bagger 287 (1976), Bagger 288 (1978), Bagger 291 (1993) and Bagger 293 (1995).[3]
