The most common type of heavy load truck is the tractor trailer. This truck has a single forward axle with two wheels, and three axles with four to six wheels on each axle. This is where the truck garners the name 18-wheeler, because it has a total of 18 wheels. It will haul a variety of different trailers including flatbed trailers (consisting of a single flat bed), enclosed trailers and tanks. These trucks are used for long distance hauling of dry products, produce, furniture, fuel and liquids.
