Hello; The biggest piece I've operated was a was a 65k lbs CASE excavator, I can only imagine the power of these monsters. Liebherr is finally a Swiss company and the mining excavator are build in France, Colmar. Beside that, there are many missing and you are wrong with a Kobelco or whatever. They are far away in the top ten. After watching 2 of your videos I have come to realise you have never seen any of these machines or worked in the industries they are used in. You actually have no clue on how excavators are measured in size and half of your top “10” wouldn’t even make it into the top 100 biggest excavators. Not to mention your number 1 isn’t the largest hydraulic excavator produce, that’s held by CAT 6120 excavator.
