What an awesome team of machines! Awesome video!! What a crazy, dangerous, bizarre, and utterly fascinating place that marble quarry is! -Those operators must be skilled, especially operating such large machines in such close proximity to each other! Bravo to them!  I used to run a komatsu wa700 in a quarry loading haul trucks. and to see a loader that size struggling to pick up that piece of marble you know that's a heavy sumbitch. I never understood why they cut them so unmanageable size other places cut them where they don't waste anything and are easy to manage . !  Go through all the time and expense of cutting this stone just to brake it into pieces.   I dont get it , spend massive amounts of time n money to cut such incredibly large pieces, just to tip them over to make crush n run
