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.<ref>{{Cite web |date=2018-10-28 |title=Gemeinde Schipkau - Schaufelradbagger |url=http://www.gemeinde-schipkau.de/verzeichnis/objekt.php?mandat=57007 |access-date=2023-04-19 |archive-date=2018-10-28 |archive-url=https://web.archive.org/web/20181028073742/http://www.gemeinde-schipkau.de/verzeichnis/objekt.php?mandat=57007 |url-status=dead }}</ref>

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.<ref>{{Cite web |date=2018-10-28 |title=Gemeinde Schipkau - Schaufelradbagger |url=http://www.gemeinde-schipkau.de/verzeichnis/objekt.php?mandat=57007 |access-date=2023-04-19 |archive-date=2018-10-28 |archive-url=https://web.archive.org/web/20181028073742/http://www.gemeinde-schipkau.de/verzeichnis/objekt.php?mandat=57007 |url-status=dead }}</ref>

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.

In January 2019 the municipalities that supported its move announced that the excavator was to be scrapped. Their decision was mainly due to the machine's dilapidation and damage.

In its operational life the excavator was used in the [[Tagebau Meuro mine]] from 1965 to 2002.


However, when the ''Brandenburg Landesamt für Denkmalpflege'' (State Office for the Preservation of Monuments) and state archaeological museum learned of the planned demolition from news reports, they issued a statement the excavator had acknowledged historical structure protection since 2002/2003. Although at that time, it was simply assumed that it was unnecessary to formally place it on the list of such structures. The fact that the structure was identified as historically significant was considered sufficient to declare it as protected. The Landesamt quickly made it official in February.
== Relocation ==
In 2003, the municipalities Senftenberg, Großräschen, and Schipkau decided on a joint action to preserve the opencast mining behemoth. Over the course of nearly three weeks, from 29 August to 15 September, Bagger 1473 was moved approximately {{convert|8.5|km|mi}} through the Meuro mine to a new location near the [[EuroSpeedway Lausitz]], where it was to serve as a monument to the lignite mining formerly conducted in the area. The route crossed industrial roads and rails owned by the LMBV, but public traffic was not affected.<ref>{{cite web |title= LMBV-Schaufelradbagger auf letzter Fahrt|language=de

Constructive discussions about the future of Bagger 1473 are ongoing with the local municipalities and communities.

This decision of the municipalities was mainly due to further dilapidation and vandalism. Only parts of the excavator, such as the wheel, were to be preserved.


The municipalities declared that saving the steel giant was financially impossible and that damage due to vandalism and theft was so extensive that the structure was no longer safe for people to climb onto it.

The Brandenburg Landesamt für Denkmalpflege (State Office for the Preservation of Monuments) and the state archeological museum learned of the planned detonation in the press and issued a statement that the eligibility of the excavator for protection as a historical structure had been acknowledged since 2002/2003. At that time, it was simply assumed that it was unnecessary to formally place it on the list of such structures. The fact that the structure was identified as historically significant was considered sufficient to declare it as protected. The Landesamt quickly made it official in February, due to the threat of destruction.

That did not mean, however, that the excavator had definitely been rescued. While constructive discussions about its future with the owning communities are possible, it was unclear how the structure can be preserved for the years to come and who will pay for it.<ref>{{cite news |title= Hörlitzer Schaufelradbagger ist jetzt ein Denkmal|language=de |trans-title=Hörlitz bucket-wheel excavator is now a monument|date=28 February 2019|access-date=28 May 2019|work=Lausitzer Woche|url=https://m.lausitzer-woche.de/wirtschaft/blaues-wunder-darf-bei-schipkau-nicht-gesprengt-werden_aid-37070981}}</ref>

Bagger 1473 (christened as The Blue Wonder[1][2]) is a Type SRs 1500-series bucket-wheel excavator prototype left abandoned in a field in the municipality of Schipkau in Germany.[2][3]

Technical data[edit]

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.[4]

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.[5]

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.

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. The machine was moved across industrial roads and railways owned by the LMBV but public traffic was not affected.[6]

When Bagger 1473 became popular with the urban explorers, it was misidentified as Bagger 258 because of markings found on its information plate.[7]

Scrapping[edit]

In January 2019 the municipalities that supported its move announced that the excavator was to be scrapped. Their decision was mainly due to the machine's dilapidation and damage. It was financially impossible to maintain and because vandalism and theft had become so extensive, the structure was no longer safe for people. Parts of the excavator would be preserved, such as its wheel.[8]

However, when the Brandenburg Landesamt für Denkmalpflege (State Office for the Preservation of Monuments) and state archaeological museum learned of the planned demolition from news reports, they issued a statement the excavator had acknowledged historical structure protection since 2002/2003. Although at that time, it was simply assumed that it was unnecessary to formally place it on the list of such structures. The fact that the structure was identified as historically significant was considered sufficient to declare it as protected. The Landesamt quickly made it official in February.

Constructive discussions about the future of Bagger 1473 are ongoing with the local municipalities and communities. Despite imminent demolition work being prevented, it remains unclear how the structure can be preserved and who will have financial responsibility.[9]
