Avanco Resources began this week, the copper concentrate shipment, page-123

A standard 6m shipping container can hold 30 m3. A flat bed truck as shown can carry approximately 22 tonnes. A shipping container even half full would be too much weight for the truck. There are two bobcats in the shed.

B-doubles are restricted to designated roads. The trucking company will most likely be paid by the tonne.
Provided the trucking company can deliver what quantity AVB needs and agreed price per tonne then it doesn't matter how the trucking company transports.
