[edit] Scope
Does this include the draglines used in strip-mining coal? If so, the largest buckets are much bigger than 4.5 m³; some of those are over 70 m³ (95 yd³). Gene Nygaard 18:22, 28 Dec 2004 (UTC)
A dragline doesnt 'scoop' like these machines. In a mine, they can be called Mass Excavators, or stripping shovels (or just a Shovel). more commonly you will find a shovel in a mine. The difference is that a shovel 'scoops' in a foward direction, so they can use the highwall as a material retainer, and the shovel bucket is heaped as it is elevated.
The largest masn-made machine was a Marion 6360 stripping shovel called "The captain". It worked from 1965 to the late 80's for the Southwestern Illinios Coal corp. It got its name from the "Captain Mine" it worked. It weighed 28 million pounds, and possessed a 180 cubic yard bucket.
Thie Marion 6360 was larger than the NASA transporter, Big Muskie, and any of the Bagger machines. It receives little credit and has been, almost, virtually forgotten.
[edit] Bucket
I work in as a supervisor with a construction company, we use a cat 375, and we have 2 12yd³ buckets and a 9yd³ one. This being different than what’s indicated on Caterpillars webpage, and is not in my Spec book. It’s a 3rd party bucket, but I know we are not the only contractor using larger buckets.

[edit] Size
On Caterpillars webpage for there 385C L http://www.cat.com/cda/layout?m=37840&x=7 they have the Operating Weight of 187360 lb / 84980 kg this being larger than what was indicated I updated it. Zath42 22:07, 8 May 2005 (UTC)

"Bucket wheel excavator", apparently - Omegatron July 5, 2005 00:00 (UTC)
- That would be machines that dig out relatively soft materials (often coal) from open mines. In one end it has a large wheel with buckets that do the digging, and as the wheel rotates, the buckets will empty themselves to a conveyor belt as they are turned upside down. The materials are then sorted and the unuseable (is that a correct word?) items are put on another belt to form a pile in the other end of the machine, while the useable parts are transported to a production/handling facility by trucks, trains or conveyor belts.

[edit] What is this tool called?
At the end of the machine a unit is mounted in order to hammer concrete to small pieces, but what is the english/american word for it? In Denmark it would probably be "betonhammer", which translates to "concrete hammer", but I assume that especially americans could nickname it a bit more exotic than that? G®iffen 16:19, 28 September 2006 (UTC)
We call that a Hydraulic Hammer or Breaker.

[edit] Rubber Duck
I've heard excavators described colloquially on construction sites in Ireland as "rubber ducks", but have no knowledge of why or how widespread this usage is. I'd add a link from Rubber duck (disambiguation), but I have no reference. Has anyone else any more information? jlang 14:38, 11 October 2007 (UTC)
"Rubber ducks" we call just wheeled excavators. Like Kamatsu PW160. Roso (unregistered) —Preceding unsigned comment added by 195.136.120.230 (talk) 19:30, 22 April 2008 (UTC)
[edit] vandals
I have removed some vandalisation but I would guess there is some text missing in the gallery at the bottom of the page. Anyone care to rescue? —Preceding unsigned comment added by Gregpalmerx (talk • contribs) 13:49, 12 January 2008 (UTC)
