In American English, the word "truck" hashistoricallybeen preceded bya word describing the type of vehicle, such as a "tanker truck". In British English, preference would lie with "tanker" or "petrol tanker".
The intention of a trailer coupler is to secure the trailer to the towing vehicle. It is an important piece, as the trailer couple attaches to the trailer ball. This then forms a ball and socket connection.It allows for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. The trailer ball shouldbe mountedto the rear bumper or to a drawbar, which may be removable. The drawbar secures to the trailer hitch by inserting it into the hitch receiver and pinning it.
The three most common types of couplers used are straight couplers, A-frame couplers, and adjustable couplers.Another option is bumper-pull hitches in which case draw bars can exert a large amount of leverage on the tow vehicle.This makes it harder to recover from a swerving situation (thus it may not be the safest choice depending on your trip).
In the United States, shipments larger than about 7,000 kg (15,432 lb)are classifiedas truckload freight (TL). It is more efficient and affordable for a large shipment to have exclusive use of one larger trailer. Thisis opposedto having to share space on a smaller Less than Truckload freight carrier.
The public idea of the trucking industry in the United States popular culture has gone through many transformations.However, images of the masculine side of trucking are a common theme throughout time.The 1940's first made truckers popular, with their songs and movies about truck drivers. Then in the 1950's theywere depictedas heroes of the road, living a life of freedom on the open road.Trucking culture peaked in the 1970's as theywere glorifiedas modern days cowboys, outlaws, and rebels. Since then the portrayal has come with a more negative connotation as we see in the 1990's.Unfortunately, the depiction of truck drivers went from such a positive depiction to that of troubled serial killers.
"Six Day on the Road" was a trucker hit released in 1963 by country music singer Dave Dudley. Bill Malone is an author as well as a music historian.He notes the song "effectivelycaptured both the boredom and the excitement, as well as the swaggering masculinity that often accompanied long distance trucking."
The basics of all trucks are not difficult, as they share common construction.They are generally made of chassis, a cab, an area for placing cargo or equipment, axles, suspension, road wheels, and engine and a drive train. Pneumatic, hydraulic, water, and electrical systems may also be present. Many also tow one or more trailers or semi-trailers, which also vary inmultipleways but are similar as well.
