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.
A six wheel dump truck can haul about 10 ton. A 10 wheeler can haul about 16 ton. A tri axle can haull about 18 ton. Most dump trucks have 20', 22.5 or 24.5 tires in many different sizes.
