Talk:Bucket-wheel excavator

45k Ton Monster Saw

This article says that the Bogatyr Mine in Kazakhstan has a Monster Saw Bucket Wheel Excavator that weighs 45000 tons, which is significantly more than the 14,000 ton Baggers in Germany.

Yes, it certainly is big. --Mathew5000 (talk) 21:56, 23 July 2008 (UTC)

Guinness World Record

This wikipedia article says that Bagger #293 is recognised by Guinness World Records as the largest land vehicle. However the German wikipedia article said #288 was the largest. These claims seem contradictory. Ceinturion (talk) 18:46, 29 September 2008 (UTC)

The German article has been revised. #288 was not the biggest, it was the first of the series of big excavators. Another detail: Guinness World Records seemed to have dropped the record in the books 2007 and 2008, but it is back in the book 2009. In summary the article now says that the record is recognised by the Guinness World Records 2001–2009. Ceinturion (talk) 15:30, 20 June 2009 (UTC)

SRs 8000 confusion

RB293 is the name of one excavator of the type SRs 8000. They are not two different excavators. Therefore I removed the confusing statement that SRs 8000 is now the biggest excavator instead of RB293.

The confusion may have been caused by the English version of the TAKRAF website. The German version is clearer:

• 'The biggest machine built, the Tenova TAKRAF SRs 8000, has a weight of 14.200 t and moves 240,000 m³ of overburden per day.' [1] versus
• 'Der größte Schaufelradbagger ist der Tenova TAKRAF SRs 8000 (RB 293). Bei einem Gewicht von 14.200 t bewegt er 240.000 m³ Abraum pro Tag.' [2]

Number of excavators at Hambach

I see a dozen excavators at http://maps.google.com/maps?ll=50.908987,6.514549&spn=0.050874,0.154324 - about one per track. Plus a few more farther north, though that image is very clearly stitched from two passes, so it's harder to guess how many. Article says "five". Are some of these excavators not bucket wheel excavators? I notice we have no article for "Bucket Chain Excavator", which are a possibility, I guess: only about five of the excavators in the southern mine leave the curved scar that I'd expect from a bucket wheel. —Preceding unsigned comment added by DewiMorgan (talk • contribs) 15:00, 23 October 2009 (UTC)

Use in the U.S.

I was looking at the article and it says that bucket-wheeled excavators are used mostly in Europe. I was wondering if anyone knows how many mining operations use them in the U.S.? When I did a quick google search I was only able to find some companies that repair or manufacture them, not necessarily where they are used. Thanks. —Preceding unsigned comment added by Franko547 (talk • contribs) 22:08, 8 April 2010 (UTC)

Units

Apparently bucket wheel excavators built by ThyssenKrupp move 100 to 12,500 fm3/hr. What is fm3, here? The only explanation I can find is cubic fermis or cubic femtometers, but those are clearly not right. 174.51.22.23 (talk) 22:56, 9 March 2013 (UTC)

File:Garzweiler Tagebau-1230.jpg to appear as POTD soon

Hello! This is a note to let the editors of this article know that File:Garzweiler Tagebau-1230.jpg will be appearing as picture of the day on July 14, 2015. You can view and edit the POTD blurb at Template:POTD/2015-07-14. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks!

Picture of the day

Bucket-wheel excavators (BWEs) are heavy equipment used in surface mining. The primary function of a BWE is to act as a continuous digging machine in large-scale open pit mining operations. These BWEs were photographed at the Garzweiler surface mine in Germany.Photograph: Raimond Spekking
