Bagger 1473
bucket-wheel excavator
Bagger 1473 (christened as The Blue Wonder) is a Type SRs 1500-series bucket-wheel excavator prototype left abandoned in a field in the municipality of Schipkau in Germany.
Technical data
The bucket wheel excavator had a power of 5555 kW during operation and was supplied with a 6 kV power cable.
Overall, the bucket wheel excavator is about 50 meters high and about 171.5 meters long. The six-section crawler undercarriage, with a maximum travel speed of 6 meters per minute, carries the total mass of 3850 tons.
With 10 buckets of 1.5 cubic meters each and 57 pours per minute (known as the pour rate), the excavator achieves a theoretical mining capacity of 5130 cubic meters per hour. The bucket wheel diameter is 12.5 meters and the cutting speed is 3.73 meters per second.
The design of the wheel boom, with a length of 67 meters, enables an excavation height of up to 35 meters and an excavation depth of up to 15 meters.
History
The excavator was used at the Tagebau Meuro mine from 1965 to 2002.
After it was withdrawn from service, the municipalities Senftenberg, Großräschen, and Schipkau decided on a joint action to preserve the opencast mining machine. Between 29 August to 15 September 2003, Bagger 1473 was moved approximately 8.5 kilometres (5.3 mi) from the Meuro mine to near the EuroSpeedway Lausitz, where it would serve as a monument to the area's former lignite mining.

Why this record matters
“Bagger 1473” is worth following because a concise public description often conceals a longer documentary argument. Here, Bagger, bucket-wheel and excavator provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 15, 2026. The linked authority identifier is Q60687981. The first chronological checks are 1473, 1500, 1965 and 2002.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
