Trailer (vehicle)
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials. 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. United States In the United States, the term is sometimes used interchangeably with travel trailer and mobile home, varieties of trailers and manufactured housing designed for human habitation. Their origins lay in utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are placed for habitation. In the United States trailers ranging in size from single-axle dollies to 6-axle, high, long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or "18-wheeler", carries a large percentage of the freight that travels over land in North America. Types ...

Semi-trailer Truck
A semi-trailer truck, also known as a semitruck, (or semi, eighteen-wheeler, big rig, tractor-trailer or, by synecdoche, a semitrailer) 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. Regional configurations Europe The noticeable difference between tractor units in Europe and North America is that almost all European models are cab over engine (called "forward control" in the UK), while the majority of North American trucks are "conventional" (called "normal control" or "bonneted" in the UK). European trucks, whether straight trucks or fully articulated, have a sheer face on the front. This allows shorter trucks with longer trailers (with larger freight capacity) within the legal maximum total length. Furthermore, it offers greater maneuverability in confined areas, a more balanced weight-distribution, and better overall view for the driver. The m ...

Teaser Campaign
A teaser (or more specifically teaser trailer) is a mini- trailer and a form of teaser campaign advertising that focuses on film and television programming. It is a videography pre-release move or television show advertisement. Short in length, teaser trailers contain little material from the advertised content to be released. Frequently, they contain hinted, cryptic, curiosity-inducing messages. Methods of this nature are designed to pique audience interest and anticipation, as well as increase the hype of the advertised content before release of its trailer. The length of a teaser trailer is usually only around 20–30 seconds. It is generally created during the shooting of the film or program and released before the completion of shooting. For films A teaser trailer is a short video segment related to an upcoming film, television program, video game, or similar, that is usually released long in advance of the product, so as to "tease" the audience; an early example of the tea ...

Trailer (promotion)
A trailer (also known as a preview, coming attraction or attraction video) is a commercial advertisement, originally for a feature film that is going to be exhibited in the future at a movie theater/cinema. It is a product of creative and technical work. Movie trailers have now become popular on DVDs and Blu-ray discs, as well as on the Internet and mobile devices. Of some 10 billion videos watched online annually, film trailers rank third, after news and user-created video. The trailer format has been adopted as a promotional tool for television shows, video games, books, and theatrical events/concerts. History The first trailer shown in an American film theater was in November 1913, when Nils Granlund, the advertising manager for the Marcus Loew theater chain, produced a short promotional film for the musical ''The Pleasure Seekers'', opening at the Winter Garden Theatre on Broadway. As reported in a wire service story carried by the Lincoln, Nebraska ''Daily Star'', t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailer (computing)
In information technology, a trailer or footer refers to supplemental data (metadata) placed at the end of a block of data being stored or transmitted, which may contain information for the handling of the data block, or simply mark the block's end. In data transmission, the data following the end of the header and preceding the start of the trailer is called the payload or body. It is vital that trailer composition follow a clear and unambiguous specification or format, to allow for parsing. If a trailer is not removed properly, or part of the payload is removed thinking it is a trailer, it can cause confusion. The trailer contains information concerning the destination of a packet being sent over a network so for instance in the case of emails the destination of the email is contained in the trailer Examples * In data transfer, the OSI model's data link layer The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking.

Construction Trailer
Construction trailers are mobile structures (trailers) used to accommodate temporary offices, dining facilities and storage of building materials during construction projects. Hook-ups Typically, trailers need to be equipped with telephone lines and electrical power. Lavatories are usually provided for separately. They are often skid-mounted, on trailers, or put on piles. Construction trailers are often manufactured using traditional stick-frame construction. Intermodal containers are also being converted into construction trailers. Use in different countries United States Municipalities can require the use of construction trailers to be subject to permit proceedings. The City of Fremont, California, for example, publishes its permit requirements on its municipal website. Enclosed Cargo Trailers are a very popular tool used by many in the construction industry. Keeping equipment and materials clean and dry are a high priority to anyone in the construction industry. These trail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Classroom
A portable classroom (also known as a demountable or relocatable classroom, portables, bungalows), is a type of portable building installed at a school to temporarily and quickly provide additional classroom space where there is a shortage of capacity. They are designed so they may be removed once the capacity situation abates, whether by a permanent addition to the school, another school being opened in the area, or a reduction in student population. Such buildings would be installed much like a mobile home, with utilities often being attached to a main building to provide light and heat for the room. Portable classrooms may also be used if permanent classrooms are uninhabitable, such as after a fire or during a major refurbishment. Sometimes, the portable classrooms are meant to be long-lasting and are built as "portapacks". A portapack combines a series of portables and connects them with a hallway. Portapacks are usually separated from the main building but can connect to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Home
A mobile home (also known as a house trailer, park home, trailer, or trailer home) is a prefabricated structure, built in a factory on a permanently attached chassis before being transported to site (either by being towed or on a trailer). Used as permanent homes, or for holiday or temporary accommodation, they are often left permanently or semi-permanently in one place, but can be moved, and may be required to move from time to time for legal reasons. Mobile homes share the same historic origins as travel trailers, but today the two are very different, with travel trailers being used primarily as temporary or vacation homes. Behind the cosmetic work fitted at installation to hide the base, mobile homes have strong trailer frames, axles, wheels, and tow-hitches. History In the United States, this form of housing goes back to the early years of cars and motorized highway travel. It was derived from the travel trailer (often referred to during the early years as "house traile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatbed Trolley
A flatbed trolley a common form of freight transport in distribution environments, for moving bulk loads. Trolleys can aid in reducing effort required to move a load by allowing the user to pull or push instead of lift and carry. A very simple design offers a basic flat platform with four casters and a fixed handle which is used to either push or pull the platform with the load on the platform. Without a flat surface it becomes an open frame trolley and without a handle it is a bogie or dolly. A flatbed trolley is also sometimes called a dray, but the term dray is also used to refer to a truck with no sides. Materials The frame is usually fabricated steel. The primary flatbed surface can be constructed from wooden boards, plastic, steel or mesh. Flatbed casters can vary dramatically, made of solid rubber, air filled pneumatic or cast iron. The caster is generally the component on the flatbed trolley that limits the safe working capacity. Types There are many types of speciali ...

Bicycle Trailer
A bicycle trailer is a motorless wheeled frame with a hitch system for transporting cargo by bicycle. It can greatly increase a bike's cargo capacity, allowing point-to-point haulage of objects up to 4 cubic yards (3 cubic metres) in volume that weigh as much as half a ton. Types Different types of trailer are designed for various purposes, cargo requirements and riding conditions: By number of wheels * Single-wheel: a single rear-mounted wheel. Though of limited towing capacity, this design tends to be more stable (when moving) than trailers with two or more wheels. The single wheel can tilt from side to side when cornering (as the bicycle itself does,) allowing for coordinated turns at relatively high speed. The connection to the bicycle is simpler than a two-wheeled trailer since only two degrees of freedom are required- the trailer tilts with the towing bicycle. * Two-wheel: A two-wheel design makes possible much greater load carrying capacity and a wider cargo bed. ...

Boat Trailer
A boat trailer is designed to launch, retrieve, carry and sometimes store boats. Commercial boat trailers Commercial hydraulic boat trailers are used by marinas, boat yards, boat haulers, boat dealers and boat builders. Generally this type of trailer is not used for storage of the boat. Self-propelled Self-propelled boat movers are not strictly trailers, but hydraulically operated boat movers, with their own tractor unit. They share all of the features of hydraulic boat trailers. Non-commercial boat trailers This type of trailer is usually used by the boat owner/operator. The trailer is also used for storage. * Roll-on, also known as a "Roller style trailer", uses rubber and/or polyurethane rollers for ease of launching and loading a boat. * Glide-path, also known as a "Float-on style trailer", allows the boat to float onto the trailer; after the trailer has been partially submerged (usually of the trailer).
