Scottfisher, can you add the geographical location of Manitowok in the photo caption? Thanks! Badagnani 00:55, 17 August 2005 (UTC)

Sure, Not a problem, I know the history of "Manny"; It came from the Nevada Test Site, then went to Lawrence Livermore National Laboratory in California, now at to Oakridge, Tennessee, ORNL. All are Department of Energy sites, in the USA. I think Manny is up for sale now. Regards, Scotty

[edit] Shovel vs Dragline

I believe Big Brutus is technically a "shovel", not a dragline (one lifts, the other drags). In the article, Big Brutus is referred to as a "dragline shovel". Is there such a thing?

The external link at the bottom of the article is a website that calls Big Brutus a "electric mining shovel", not a dragline.


There is no such thing as a "dragline shovel". Big Brutus is a rope shovel which is completely different from a dragline.

[edit] Caterpillar tracks versus feet

Regarding the statement:

In all but the smallest of draglines, movement is accomplished by "walking" using feet or pontoons, as caterpillar tracks place too much pressure on the ground

What kind of feet are these that they put less pressure on the ground than caterpillar tracks? Is it even true? That GEM thing linked near the bottom of the page is pictured on caterpillar tracks. --ToobMug 12:48, 12 December 2006 (UTC)
