Wow!
that thing is huge! I didn't know you worked in the steel industry Craig, looks like operating that beast would be a blast!
I just started a rebuild of a pot hauler about two weeks ago as a matter of fact. It's also based on a 621E scraper but is one of only 3 ever built in a partnership with CAT. The cab is built by Cat for Kress amongst a few other components.
This is a big project for me. First time seeing and working on one. We have a 425K budget and has to be back at the steel plant for June 15th!
Needless to say I'm gonna be busy the next few months!
I'll make sure I get some pics as the build goes and post.
