Stanchion
A stanchion () is a sturdy upright fixture that provides support for some other object. It can be a permanent fixture. Types In architecture stanchions are the upright iron bars in windows that pass through the eyes of the saddle bars or horizontal irons to steady the leadlight. The French call the latter ''traverses'', the stanchions ''montants'', and the whole arrangement ''armature''. Stanchions frequently finish with ornamental heads forged out of the iron. Stanchions are also the metal supporting members of lighting mounted from a lower elevation. This includes the metal inclined member for mounting a streetlight to a telephone or power pole, and the dedicated metal vertical support of a self-supporting or bottom-fed streetlight. In this case, the stanchion pole may double as the Electrical conduit, raceway for the electrical feed to the lighting. In industrial installations, walkway lighting may be mounted with a stanchion that is secured to a hand-rail. Stanchion lights ...

Flat Wagon
Flat wagons (sometimes flat beds, flats or rail flats, US: flatcars), as classified by the International Union of Railways (UIC), are railway goods wagons that have a flat, usually full-length, deck (or 2 decks on car transporters) and little or no superstructure. By contrast, open wagons have high side and end walls and covered goods wagons have a fixed roof and sides. Flat wagons are often designed for the transportation of goods that are not weather-sensitive. Some flat wagons are able to be covered completely by tarpaulins or hoods and are therefore suitable for the transport of weather-sensitive goods. Unlike a "goods wagon with opening roof", the loading area of a flat is entirely open and accessible once the cover is removed. Flats form a large proportion of goods wagons; for example in 1998 they comprised 40% of the total goods fleet owned by the German carrier, DB, the overwhelming majority of which were flat wagons with bogies. Typical goods transported by these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goalpost
In sport, a goal may refer to either an instance of scoring, or to the physical structure or area where an attacking team must send the ball or puck in order to score points. The structure of a goal varies from sport to sport, and one is placed at or near each end of the playing field for each team to defend. For many sports, each goal structure usually consists of two vertical posts, called ''goal posts'', supporting a horizontal ''crossbar''. A ''goal line'' marked on the playing surface between the goal posts demarcates the goal area. Thus, the objective is to send the ball or puck between the goal posts, under or over the crossbar (depending on the sport), and across the goal line. Other sports may have other types of structures or areas where the ball or puck must pass through, such as the basketball hoop. Sports which feature goal scoring are also commonly known as invasion games. In several sports, sending the ball or puck into the opponent's goal structure or area is ...

Dairy Farming
Dairy farming is a class of agriculture for long-term production of milk, which is processed (either on the farm or at a dairy plant, either of which may be called a dairy A dairy is a business enterprise established for the harvesting or processing (or both) of animal milk – mostly from cows or buffaloes, but also from goats, sheep, horses, or camels – for human consumption. A dairy is typically located on ...) for eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including Rotary milking parlor, rotary parlors, the milking pipeline, and Automatic milking, automatic milking systems that were commercially developed in the early 1990s. Milk preservation methods have improved starti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standing Passenger
In urban public transport, provision is made for standing passengers, often called straphangers or standees, to rationalize operation and to provide extra capacity during rush hour. Occurrence On crowded rapid transit urban lines, while most travelers may be seated during off-peak services, only a limited proportion will be seated during the peak services. The longer the journey, the less willing passengers are to stand. On intercity rail or coach services, the willingness among passengers to stand is often low, or it may even be prohibited, with reserved seating to ensure that all passengers can be seated. In aviation, safety measures require all passengers and crew to be seated during take-off and landing, so airlines do not allow passengers to travel without a seat. However, in 2010, Ryanair, a low-cost airline proposed a "vertical seat" design for use by standing passengers on its aircraft.The Telegraph (London)"Ryanair to sell £5 tickets for standing-room only flights" La ...

Bicycle Fork
A bicycle fork is the part of a bicycle that holds the front wheel. A fork typically consists of two ''blades'' which are joined at the top by a fork ''crown.'' The crown is often at the front. Most suspension forks have an arch connecting the two side of the lowers (the part connected to the axle.) It is often in front of the stanchions (shaft the lowers slide on) but not always. Above the crown, a ''steerer tube'' attaches the fork to the bicycle and the handlebars (via a stem) allowing the rider to steer the bicycle. The steerer tube of the fork interfaces with the frame via bearings called a headset mounted in the head tube. At the bottom of the fork, ''fork ends'' hold the wheel. Usually, either the axle is bolted to the fork, or a ''quick release skewer'' passes through a hollow axle, clamping the axle to the fork. The term ''fork'' is sometimes also used to describe the part of a bicycle that holds the rear wheel, which on 19th century ''ordinary'' or ''penny-farthin ...

Streetlight
A street light, light pole, lamp pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led. Many lamps have light-sensitive photocells that activate the lamp automatically when needed, at times when there is little-to-no ambient light, such as at dusk, dawn, or at the onset of dark weather conditions. This function in older lighting systems could be performed with the aid of a solar dial. Many street light systems are being connected underground instead of wiring from one utility post to another. Street lights are an important source of public security lighting intended to reduce crime. History Preindustrial era Early lamps were used by Greek and Roman civilizations, where light primarily served the purpose of ...

Flatbed Truck
A flatbed truck (or flatbed lorry in British English) is a type of truck which can be either articulated or rigid. As the name suggests, its bodywork is just an entirely flat, level 'bed' with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require more space than is available on a closed body. Road trucks A flatbed has a solid bed, usually of wooden planks. There is no roof and no fixed sides. To retain the load there are often low sides which may be hinged down for loading, as a 'drop-side' truck. A 'stake truck' has no sides but has steel upright pillars, which may be removable, again used to retain the load. Loads are retained by being manually tied down with ropes. The bed of a flatbed truck has tie-down hooks around its edge and techniques such as a trucker's hitch are used to tighten them. Weather protection is optiona ...

Semi-trailer
A semi-trailer is a trailer without a front axle. In the United States, the term is also used to refer to the combination of a truck and a semi-trailer; a tractor-trailer. 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, or the tail of another trailer. The other portion of the semi-trailer's weight is semi-supported (half-supported) by its own wheels, which only support 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 full trailers, which have both front and rear axles. Ease of backing is cited as one of the semi's chief advantages. A road tractor coupled to a semi-trailer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Aircraft
A cargo aircraft (also known as freight aircraft, freighter, airlifter or cargo jet) is a fixed-wing aircraft that is designed or converted for the carriage of air cargo, cargo rather than passenger aircraft, passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries. Aircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, numerous wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft. By 2015, dedicated freighters represent 43% of the 700 billion ATK (available tonne-kilometer) capacity, while 57% is carried in Airliner#Baggage ...

Bollard
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. It now also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures, whether intentional from ram-raids and vehicle-ramming attacks, or unintentional losses of control. Etymology The term is probably related to bole, meaning a tree trunk. The earliest citation given by the ''Oxford English Dictionary'' (referring to a maritime bollard) dates from 1844, although a reference in the ''Caledonian Mercury'' in 1817 describes bollards as huge posts. History Wooden posts were used for basic traffic management from at least the beginning of the 18th century. An early well-documented case is that of the "two oak-posts" set up next to the medieval Eleanor cross at Waltham Cross, Hertfordshire, in 1721, at the expense of the Society of Antiqua ...
