Oops...







If an excavator can load a 50m3 truck in 5 minutes, 12 trucks are required, to keep the digger @ 100% use plus hauling time, which would presumably be a 3 hour return trip per truck so that is a fleet of 36 trucks (I think...)...


so, doing it 24/7 carrying 50m3 each arriving at port every 5 minutes? Delivering @ 50m3 per truck every 5 minutes?
50m3x12 Trucks per hour =600 Tonne per hour, per digger.




Thats 10 tonnes a minute..$40000


Per Digger.


Anyway...off 'sploring.
