Amazing excavators at work, trucks-dumpers,wheel loaders, bulldozers in action,heavy transportations, cat - caterpillar, Komatsu, Liebherr, Volvo,hitachi,crushers and attachments working and digging in mud and mines for coal and quarries.  Wow! No tyre slip. No excessive turning! Low rev! Steady pase that look slow but is really efficient. Good operator!  Here's an operator who knows how its done! Ease, steady and articulate with every move. Neatly keeps cleaned up as he goes, and his timing is impeccable!!! Respects his machine ..  This machine is massive. Just one scoop amd the trucks are on their way. Awesome.  I have often wondered what they use the conveyor belt system for. I really enjoy watching the excavators and trucks and wheel loaders it brings back a l[t of good memories.  Looks like they welded additional plates of steel on the bucket to increase the volume of material it can scoop! Badass idea.  But for the loaded trucks its pure stress, normaly it should take about 3passes to fill a truck. Its kind a ok if the material does not consist of heavy falling parts, but nevertheless it stresses the material more than necessary.  It's like having the body off a Volvo A60 where the shovel should be. Those are ambitious extensions / greedy boards on the shovel. Nice to see an operator not crucifying the tyres (tires) or the transmission every time he goes into the pile, yet still manages to fill the shovel.  I'm engineer at copper mine butt I'm so interested in those machinery...I drive loader in these days!! amazing experience ❤️  It looks like he has a joystick control for the steering. Imagine what these things will look like 100 years from now. They will make this thing look like a toy.
