Navajo Mine Railroad
The Navajo Mine is a surface coal mine owned and operated by Navajo Transitional Energy Company (NTEC), LLC in New Mexico, USA, within the Navajo Nation. It operates of track between the Four Corners Generating Station and Navajo Mine (formerly owned by BHP). History Navajo Mine's coal lease was granted in 1957. Then in 1963 Navajo Mine began operations for Utah International. The Navajo Mine is the sole supplier of coal to the adjacent Four Corners Power Plant (FCPP). In 1977 General Electric acquired Navajo Mine from Utah International. Seven years later in 1984 BHP acquired Navajo Mine, eventually merging with BHP Billiton. In 2013 the 22nd Navajo Nation Council created Navajo Transitional Energy Company (NTEC), LLC under legislation No. 0116-13 with a vote of 7-4. By the end of that year NTEC acquired Navajo Mine. NTEC received a lease extension through the Department of the Interior and the Office of Surface Mining Reclamation & Enforcement (OSMRE) for 25-year site lease e ...

Rail Freight Transport
Rail freight transport is the use of railroads and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled per unit of energy consumed, rail transport can be more efficient than other means of transportation. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. However, shipment by rail is not as flexible as by the highway, which has resulted in much freight being h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowboy (trailer)
A lowboy (low-loader in British English, low-bed in western Canada and South Africa or float in Australia and eastern Canada) is a semi-trailer with two drops in deck height: one right after the gooseneck and one right before the wheels. This allows the deck to be extremely low compared with other trailers. It offers the ability to carry legal loads up to tall, which other trailers cannot. Lowboys are used to haul heavy equipment such as bulldozers and large industrial equipment. History The first lowboy trailer was invented in the 1920s; it featured a riveted gooseneck and solid rubber tires. The first detachable gooseneck trailer, referred to as an RGN (Removable goose neck), was invented in 1958. Types The lowboy trailer comes in several types, for a wide range of tasks. Some types are: * Fixed gooseneck (FGN): allows a longer deck length and has the lightest weight. These are lower trailers than normal, with low-profile tires, usually with drop ramps in the rear to fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk & Western
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway to form today’s Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired between 1964 and 1965. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated of road on of track from North C ...

Ferrocarriles Nacionales De México
Ferrocarriles Nacionales de México (better known as N de M and especially in its final years as FNM) was Mexico's state owned railroad company from 1938 to 1998, and prior to 1938 (dating from the regime of Porfirio Díaz), a major railroad controlled by the government that linked Mexico City to the major cities of Ciudad Juárez, Nuevo Laredo and Matamoros on the U.S. border. The first trains to Nuevo Laredo from Mexico City began operating in 1903. History The beginnings of rail transport in Mexico date back to the concessions granted by Maximilian I of Mexico, mostly to foreign companies, and continued by Benito Juárez. In 1898, José Yves Limantour proposed a system of concessions of the railway companies on the future lines to be built from 1900. That same year the Secretariat of the Treasury promulgated the first General Railway Law. This law established a system whereby concessions would be granted to companies to lay railway lines only when they satisfied the eco ...

Loader (equipment)
A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car). There are many types of loader, which, depending on design and application, are variously called a bucket loader, front loader, front-end loader, payloader, high lift, scoop, shovel, skip loader, wheel loader, or skid-steer. Description A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground. A loader is commonly used to move a stockpiled material from ground level and deposit it into an awaiting dump truck or into an open trench excavation. The loader assembly may be a removable ...

Catenary
In physics and geometry, a catenary (, ) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. The curve appears in the design of certain types of arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette, MathWorld or, particularly in the materials sciences, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A hanging chain will assume a shape of least potential energy which is a catenary. Galil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
