Build an Excavator from Scratch

[pufferfish]

At the beginning of my research for an excavator i've found a flyer from liebherr. There was the model 966 noticed as a perfect fit for 30 tons dumpers. My dumper is a 30 tons one. Thereby the 966 became my model for principal sizes.
Later I was surprised too that you need a monstrous excavator to load a small dumper
