Semi-trailer
A semi-trailer is a trailer (vehicle), trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a ''semi-trailer truck'' (also known simply as a "semi-trailer", "tractor trailer", or "semi" in the United States). A large proportion of a semi-trailer's weight is supported by a tractor unit, or a detachable front-axle assembly known as a dolly (trailer), dolly, or the B-Train, tail of another trailer. The semi-trailer's weight is semi-supported (half-supported) by its own wheels, at the rear of the semi-trailer. A semi-trailer is normally equipped with landing gear (legs which can be lowered) to support it when it is uncoupled. Many semi-trailers have wheels that are capable of being totally dismounted and are also relocatable (repositionable) to better distribute load to bearing wheel weight factors. Semi-trailers are more popular for transport than Trailer (vehicle)#Full, full trailers, which have both front and rear axles. Ease of backing i ...

Semi-trailer Truck
A semi-trailer truck (also known by a wide variety of other terms – see below) is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a ''fifth wheel''. Other terms There are a wide variety of English-language terms for a semi-trailer truck, including: American English: *Semi-trailer *Semi-truck *Truck & trailer *Semi *Big rig *Tractor-trailer *Eighteen-wheeler British English: * Articulated lorry * Artic (short for articulated lorry) * Juggernaut *Heavy Goods Vehicle/HGV Canadian English: *Transport truck *Transfer truck Regional configurations Europe The main difference between tractor units in Europe and North America is that European models are cab over engine (COE, called "forward control" in the United Kingdom), while the majority of North American trucks are "conventional" (called "normal control" or "bonneted" in the UK). European trucks, whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trailer (vehicle)
A trailer is an unpowered vehicle Towing, towed by a powered vehicle. It is commonly used for the transport of goods and materials. There are two general categories of trailers: the full trailer and the semitrailer. A full trailer is a type of trailer whose entire weight is supported by its own wheels, with no weight transferred to the towing vehicle. In contrast, a semi-trailer is designed so that a portion of its weight is carried by its own wheels, while the remaining weight is borne by the towing vehicle. Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers. Trailers have been used for thousands of years, predating the invention of the automobile. Before the advent of the wheel, early humans employed the concept of trailering by using drag sleds to transport goods. While the two wheel war chariot is one of the ...

B-Train
A road train, also known as a land train or long combination vehicle (LCV) is a semi-trailer truck, semi-trailer used to move road freight more efficiently than single-trailer semi-trailers. It consists of one semi-trailer or more connected together with or without a tractor unit, prime-mover. It typically has to be at least three Semi-trailer, trailers and one Tractor unit, prime-mover. Road trains are often used in areas where other forms of heavy transport (freight train, cargo aircraft, container ship) are not feasible or practical. History Early road trains consisted of traction engines pulling multiple wagons. The first identified road trains operated into South Australia's Flinders Ranges from the Port Augusta area in the mid-19th century. They displaced bullock teams for the carriage of minerals to port and were, in turn, superseded by railways. During the Crimean War, a traction engine was used to pull multiple open trucks. By 1898 steam traction engine trains wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It was founded in 1918 in Detroit, after August Fruehauf created the semi-trailer and launched a new industry. The Fruehauf trailer company introduced revolutionary inventions to trucking and transportation with hydraulic dump trailers, bulk tanker trailers, and automatic fifth-wheel couplings among their more than one thousand patents, including the shipping container in 1956. Expanding across the country, Fruehauf had 16 plants and more than 80 distributorships for parts and service. Globally, the company expanded into Europe, South America, and Asia.

Tractor Truck
A tractor unit, also known as a truck unit, lorry unit, power unit, prime mover, ten-wheeler, semi-tractor, semi-truck, semi-lorry, tractor cab, truck cab, lorry cab, big rig tractor, big rig truck or big rig lorry or simply a tractor, truck, lorry, semi, big rig or rig, is a characteristically heavy-duty towing engine that provides motive power for hauling a towed or trailered load. The largest such vehicles are similar to locomotives. These fall into two categories: heavy- and medium-duty military and commercial rear-wheel-drive semi-tractors used for hauling semi-trailers, and very heavy-duty typically off-road-capable, often 6×6, military and commercial tractor units, including ballast tractors. It should not be confused with a tractor-trailer which is a combination of a tractor unit and semi-trailer, whereas a ''tractor unit'' describes only the tractor portion. Overview Tractor units typically have large-displacement diesel engines for power, durability, and econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolly (trailer)
A dolly is an unpowered vehicle designed for tow hitch, connection to a tractor unit, truck or prime mover vehicle with strong traction power. United States Classification by axle configuration There are several types of dolly Bogie#Articulated lorries (tractor-trailers), bogie: * Full trailer – 2 axles (4 wheels), with a Drawbar (haulage), draw bar which also controls the trailer's front axle steering. The draw bar does not take load of the full trailer. Heavy full trailer needs to have its own brakes remotely controlled by the prime mover vehicle. * Semi-trailer – 1 axle (2 wheels), without the front axle but have a landing gear. Large semi-trailer of truck size is designed for connection via the Fifth wheel coupling, fifth wheel on the tractor unit or the semi-trailer truck. Small semi-trailer such as travel trailer and boat trailer is designed for connection via a tow hitch of a passenger vehicle. Either the fifth wheel or the tow hitch takes up to half the load of ...
