In the context of the foreign exchange market, traders liquidate their positions in various currencies to take up positions in safe-haven currencies, such as the US dollar. Sometimes, the choice of a safe haven currency is more of a choice based on prevailing sentiments rather than one of economic statistics.
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.
The maximum per truck load is 22 cubic yards of mulch, 15 cubic yards of topsoil, or 12 yards of stone per delivery. We do have semi-trucks which can haul more material per load, although these trucks are limited to operating only on larger commercial sites.
