Everything about this is just pure precision and excellence. The control from the CAT operator, how he crawls forward to tip the remaining material out, the mutual understanding between tipper drivers and CAT operator and just overall cooperation. Also the fact that the tipper drivers are trusting that the (approx) 25 tonnes of material doesn’t end up on top of them, is just brilliant.What amazes me about these machines is they are so powerful and seem indestructible but a tiny O-ring going out can stop them in their tracks.
