Bucket wheel excatavator
An end game excavator that work like the U4 Stacker (a base is placed then extension are placed to extand the range of the excavator), it can be used to build a stacker/reclaimer for ore storing or to dig a mountain.
The base have a built-in ore separator and multiple belt output to export different ressources.
The machine have an highter maintenance cost per item mined than regular Mega-excavator bu don't need Truck to transport ressources
(Maybe add an electric cost for each extention segment to adjust balance)
