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.

So cool to see the real future of energy in action. The coal mining videos are good to watch, but it's always bittersweet as you know that shit's going to poison the air.
