This is presented in a format that is (I think) aimed at kids but it still makes a pretty interesting article. http://www.minepro.com/dragline_erection/estevan.html It details the buidling, on site, of a walking dragline used in the strip mining industry. And this is a bit of an interesting site if you're into the REAL heavy equipment. http://www.stripmine.org/
Thanks Alan! That was an interesting read!
