Avanco Resources began this week, the copper concentrate shipment, page-119

Specially designed haulage trucks travel across a dirt road to a railway. That's a lot different to meandering down state roads. The biggest GVM truck you can put on Brazil roads is 74 tonne. That thing probably weighs 167 tonne GVM. If you loaded a turnpike double with 2 30 tonne containers that will only leave 13 tonne for tractor and trailers which is not enough. They would not be able to max out the load in the container.
