I randomly stumbled on this video and decided to google the model . This thing is an absolute MONSTER !!!! It has a payload capacity of 17 tonnes !! powered by a turbocharged 15 litre 6 cylinder 440 hp deisel engine with some 1800 pound feet of torque( I wonder by the time it reaches the driving wheels how much it gets multiplied) !! Empty weight 50 tonnes!I wonder what kind of feeling is it working underground must be surreal must be a great feeling must be calm and lonely at times too perhaps?
