How many tons can an standard dump truck carry?

Typical commercial US dump trucks are double-axle dually setups carrying about 10 cubic yards of material, which is about 10 short tons for typical materials like gravel or soil.

A big, heavy-duty triple-axle model might reach 15 tons. A single-axle model based on a passenger truck might only hold 3 tons. A side-dump semi trailer might hold 30 tons. Non-street legal ore transfer trucks hold up to 400 tons!
