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 thes 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.

Military Cableways In The First World War
Military cableways ( it, teleferiche militari, german: Militär-Seilbahnen) 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aerial Tramway
An aerial tramway, sky tram, cable car, ropeway, aerial tram, telepherique, or seilbahn is a type of aerial lift which uses one or two stationary ropes for support while a third moving rope provides propulsion. With this form of lift, the grip of an aerial tramway cabin is fixed onto the propulsion rope and cannot be decoupled from it during operations. In comparison to gondola lifts, aerial tramways generally provide lower line capacities and higher wait times. Terminology Because of the proliferation of such systems in the Alpine regions of Europe, the French and German names, ''téléphérique'' and ''Seilbahn'', respectively, are often also used in an English language context. ''Cable car'' is the usual term in British English, as in British English the word ''tramway'' generally refers to a railed street tramway while in American English, ''cable car'' may additionally refer to a cable-pulled street tramway with detachable vehicles; e.g., San Francisco's cable cars. ...

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 snowboard 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 consists of one or two loops of cable strung between two terminals over intermediate towers. In order to maximize th ...

Aerial Lift
An aerial lift, also known as a cable car or ropeway, is a means of cable transport in which ''cabins'', ''cars'', ''gondolas'', or open chairs are hauled above the ground by means of one or more 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 Cable Car A cable car (British English) or an aerial tramway, aerial tram (American 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 include the Roosevelt Island Tramway ( New Yor ...

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 it, Cabinovia and french: Télécabine are also used in English-language texts. The systems m ...

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 (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they 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".

Wire Rope
Steel wire rope (right hand lang lay) Wire rope is several strands of metal wire twisted into a helix forming 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''. 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, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run. Wire ropes were developed starting with min ... [...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'', 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 presidential election. Cooper was 85 years old at the time, making him the oldest person to ever be nominated for president. 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 puddle iron. He also developed numerous patents for products such as gelatin and part ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Landfill
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. 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 reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

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 "forced" or 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 air (sometimes with oxygen enrichment) 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 waste gases (flue gas) exiting from the top of the furnace. 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 reverbera ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
