Just a few useless stats on a Cat 797F (the largest dump truck in the Cat range)
Payload is a lot, easy to imagine over 100 t? Maybe more, 200 t? That's heavy, more? Yep, 363 t max
$US47,500 will buy you new rubber. A set of 6 one may ask? No that's each tyre (2009 prices).
Tyres stand over 4 m tall and each weighs over 5 t. Goodness knows what a wheel and tyre weigh together. Imagine one of them on a rear swing-out...
How many horses? Needs a lot to shift a 363 t payload at 42 mph, maybe 2,000? More? 3,000 horses? That's a stampede! No, much more Gross, 4,000 hp (2,983 kW)
How many cylinders? 8, or 10, maybe 12. More? 16? No, it's a V20 electronic common rail injection quad turbo diesel.
Gross machine operating weight, 623 t no less.
Purchase price? A good couple of $US millions maybe? Well yes, and some... POA, but more like $US 5 millions.
