Cableway
Cable transport is a broad class of transport modes that have cables. They transport passengers and goods, often in vehicles called cable cars. The cable may be driven or passive, and items may be moved by pulling, sliding, sailing, or by drives within the object being moved on cableways. The use of pulleys and balancing of loads moving up and down are common elements of cable transport. They are often used in mountainous areas where cable haulage can overcome large differences in elevation. Common modes of cable transport Aerial transport Forms of cable transport in which one or more cables are strung between supports of various forms and cars are suspended from these cables. * Aerial tramway * Chairlift * Funitel * Gondola lift * Ski lift * Zip line Cable railways Forms of cable transport where cars on rails are hauled by cables. The rails are usually steeply inclined and usually at ground level. * Cable car * Funicular Other Other forms of cable-hauled tran ...

Military Cableways In The First World War
Military cableways (, ) were used in the First World War by Kingdom of Italy, Italy and Austria-Hungary to transport supplies up to their troops in mountain sectors of the front. Troops were often in high-altitude positions during the so-called “White War”, far removed from roads, mule tracks, pathways or existing cablecars. Moreover, where such infrastructure did exist, it generally followed the easiest routes and was therefore exposed to enemy fire. Providing the troops on the front line with a reliable supply of food and ammunition therefore often required the building of new infrastructure. Building the networks Military cableways had to be built where they were needed, regardless of how difficult the terrain might be. As well as overcoming steep, impassable slopes, the engineers who built them had to deal with rockfalls and avalanches and sometimes work under enemy fire. The technical demands of the new cableways were sometimes extreme. For example, Austrian cableways h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Tramway
An aerial tramway, aerial tram, sky tram, cable car or aerial cablecar, aerial cableway, ropeway, téléphérique (French), or Seilbahn (German) is a type of aerial lift which uses one or two stationary cables for support, with a third moving cable providing propulsion. With this form of lift, the grip of an aerial tramway cabin is fixed onto the propulsion cable and cannot be decoupled from it during operation. Aerial tramways usually provide lower line capacities and longer wait times than gondola lifts. Terminology ''Cable car'' is the usual term in British English, where ''tramway'' generally refers to a railed Tram system, street tramway. In American English, ''cable car'' may additionally refer to a cable-pulled street tramway with detachable vehicles (e.g., San Francisco cable car system, San Francisco's cable cars). Consequently careful phrasing is necessary to prevent confusion. It is also sometimes called a ''ropeway'' or even incorrectly referred to as a gondo ...

Funitel
A funitel is a type of cableway, generally used to transport skiers, although at least one is used to transport finished cars between different areas of a factory. It differs from a standard gondola lift through the use of two arms attached to two parallel overhead cables, providing more stability in high winds. The name ''funitel'' is a portmanteau of the French words '' funiculaire'' and '' telepherique''. When used to transport skiers, funitels are a fast way to get to a higher altitude. Skis or snowboards have to be taken off and held during the trip. Depending on the configuration, cabins may or may not contain seats. Without seats, funitels can sometimes be uncomfortable for long trips, in the same way other large cable cars can be. Funitels combine a short time between successive cabins with a capacity of around 20 to 30 people per cabin. Overview A funitel installation employs two cables (or a single cable arranged in two loops) strung between two terminals and supp ...

Aerial Lift
An aerial lift, also known as a cable car or ropeway, is a means of cable transport in which ''cabins'', ''cars'', ''Gondola lift, gondolas'', or Chairlift, open chairs are hauled above the ground by means of one or more Wire rope, cables. Aerial lift systems are frequently employed in a mountainous territory where roads are relatively difficult to build and use, and have seen extensive use in mining. Aerial lift systems are relatively easy to move and have been used to cross rivers and ravines. In more recent times, the cost-effectiveness and flexibility of aerial lifts have seen an increase of gondola lift being integrated into urban public transport systems. Types Aerial tramway An aerial tramway, aerial tram (American English) or a cable car (British English), uses one or two stationary ropes for support while a separate moving rope provides propulsion. The grip of an aerial tramway is permanently fixed onto the propulsion rope. Aerial trams used for urban transport incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondola Lift
A gondola lift is a means of cable transport and type of aerial lift which is supported and propelled by cables from above. It consists of a loop of steel wire rope that is strung between two stations, sometimes over intermediate supporting towers. The cable is driven by a bullwheel in a terminal, which is typically connected to an engine or electric motor. It is often considered a ''continuous system'' since it features a haul rope which continuously moves and circulates around two terminal stations. In contrast, an aerial tramway operates solely with fixed grips and simply shuttles back and forth between two end terminals. The capacity, cost, and functionality of a gondola lift will differ dramatically depending on the combination of cables used for support and haulage and the type of grip (detachable or fixed). Because of the proliferation of such systems in the Alps, the and are also used in English-language texts. The systems may also be referred to as cable car ...

Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe), or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (typically greater than about 60% iron) are known as natural ore or irect shipping ore and can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel — 98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Elemental iron is virtually absent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Rope
Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite ''rope'', in a pattern known as ''laid rope''. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as ''cable laid''. Manufactured using an industrial machine known as a strander, the wires are fed through a series of barrels and spun into their final composite orientation. In stricter senses, the term ''wire rope'' refers to a diameter larger than , with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peter Cooper
Peter Cooper (February 12, 1791April 4, 1883) was an American industrialist, inventor, philanthropist, and politician. He designed and built the first American steam locomotive, the ''Tom Thumb (locomotive), Tom Thumb'', founded the Cooper Union for the Advancement of Science and Art, served as its first president, and stood for election as the Greenback Party's candidate in the 1876 United States presidential election, 1876 presidential election. Cooper began tinkering at a young age while working in various positions in New York City. He purchased a glue factory in 1821 and used that factory's profits to found the Canton Iron Works, where he earned even larger profits by assembling the ''Tom Thumb''. Cooper's success as a businessman and inventor continued over the ensuing decades, and he became the first mill operator to successfully use anthracite coal to puddling (metallurgy), puddle iron. He also developed numerous patents for products such as gelatin and participated in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltimore
Baltimore is the most populous city in the U.S. state of Maryland. With a population of 585,708 at the 2020 census and estimated at 568,271 in 2024, it is the 30th-most populous U.S. city. The Baltimore metropolitan area is the 20th-largest metropolitan area in the country at 2.84 million residents. The city is also part of the Washington–Baltimore combined statistical area, which had a population of 9.97 million in 2020. Baltimore was designated as an independent city by the Constitution of Maryland in 1851. Though not located under the jurisdiction of any county in the state, it forms part of the central Maryland region together with the surrounding county that shares its name. The land that is present-day Baltimore was used as hunting ground by Paleo-Indians. In the early 1600s, the Susquehannock began to hunt there. People from the Province of Maryland established the Port of Baltimore in 1706 to support the tobacco trade with Europe and established the Town ...

Landfill
A landfill is a site for the disposal of waste materials. It is the oldest and most common form of waste disposal, although the systematic burial of waste with daily, intermediate and final covers only began in the 1940s. In the past, waste was simply left in piles or thrown into pits (known in Archaeology, archeology as middens). Landfills take up a lot of land and pose environmental risks. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be Landfill restoration, reclaimed for other uses. Both active and restored landfill sites can have significant environmental impacts which can persist for many years. These include the release of gases that contribute to ...

Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of (sometimes oxygen enriched) air is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverberatory furnaces) are naturally aspirated, usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
