computer glitch dropped the transmission from sixth gear back to first whilst doing 60 km/h with a full load of 230 tons.
Below is what remains of a Caterpillar C175-16 – the 85L capacity V16 engine from Caterpillar’s second biggest dump truck, the 793, which has a gross power output of 1976 kW (2650 hp).
Flat out it revs at around 2500 rpm. As big as they are, engines of this size don't like to over-rev at all; 100-200 rpm over will start to do damage. There was no compression lock up, just BANG!
A new engine costs around $250k.
