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-class,[6] is a family of bucket-wheel excavators known for being one of the largest terrestrial vehicles ever made by man, with Bagger 293 its - "lead vessel" - being the largest ground vehicle in history.[7] The Type SRs 8000 classification was coined by TAKRAF to describe specifically, Bagger 293, although it is unclear if this extends to its other "sibling vehicles" within the same bulk.[8]
Bagger 293 is the largest of the Type SRs 8000s | |

Whilst the "Bagger" family may indicate a copy/series of the same vehicle type, it is more of a loose denominator to group any BWEs of similar bulk, length, height and size within the Hambach surface mine.[9][10] Indeed, some of the Baggers created aren't of the same size, construction period or even in the same built manufacturer. Bagger 293 and 288 for example, was constructed by TAKRAF and Krupp respectively.[11][12][13]
