Lets grossly overload then wonder why the truck breaks. That excavator sitting up ther like that is very likely to have the 'island' it is sitting on collapse.The dump truck was full of dirt and then it was pressed with an excavator.I drive a dump truck for a living, aint no way id let my truck get overloaded like that!!!Those poor pit trucks. Most are missing a couple of axles to be hauling heavy loads like that. There's no scales in a pit. This is where big trucks go to die!! While the excavator operator smiles from the good digging.
