Here is a good video showing haul trucks in copper mining in Atacama, Chile, South America. The first haul truck coming up the road is a smaller Caterpillar 793B. The last two haul trucks are heavier and are Liebherr T 282C at 600 tonnes of weight that is why two tractor trucks are needed to pull the weight to the copper mine place high up the subduction zone mountain ranges and arid deserts. youtube/watch?v=--12UOziMF0
