Cable Grip
A cable grip is a device for propelling a vehicle by attaching to a wire rope (called a haul rope) running at a (relatively) constant speed. The vehicle may be suspended from the cable, as in the case of aerial lifts such as a gondola lift (''télécabine''), may be guided by rails, as in a cable traction railway, or may be self-guiding, as in a button lift. Typically, multiple vehicles will use the same cable; where just one or two vehicles are in use they will tend to be attached to the cable permanently such as in funiculars. While the cable grips used in the original cable railways were manually operated, requiring considerable skill and strength, modern cable grips tend to be automatic. Given that the cable runs at a relatively constant speed, accelerating the vehicle to match the speed of the cable presents a technical difficulty; possible methods are to apply the grip gradually, to accelerate the vehicle (e.g. by guiding wheels) prior to applying the grip, or to use a ...

William Eppelsheimer
William Eppelsheimer (January 26, 1842 – June 9, 1920) was a tramway engineer known for his work on cable car systems. He was born in Alzey in Germany and studied engineering at the Polytechnikum Karlsruhe. In 1868 he left Germany by ship from Bremerhaven for the United States. Arriving in New York he changed his German first name ''Wilhelm'' to ''William.'' Eppelsheimer designed the Clay Street Hill Railroad in San Francisco. This was the first practical cable car line in the world and the first line in what was to become the San Francisco cable car system, although that line is more often attributed to its promoter, Andrew Smith Hallidie. He later designed the Eppelsheimer bottom grip for the Geary Street, Park & Ocean Railway, another San Francisco line, and this is still used by that city's surviving cable cars. Eppelsheimer went on to design the Chicago City Railway, at one time the world's largest and most profitable cable car system, and London London is ...

Cable Railways
A cable railway is a railway that uses a cable, rope or chain to haul trains. It is a specific type of cable transportation. The most common use for a cable railway is to move vehicles on a steeply graded line that is too steep for conventional locomotives to operate on – this form of cable railway is often called an incline or inclined plane, or, in New Zealand, a jigline, or jig line. One common form of incline is the funicular – an isolated passenger railway where the cars are permanently attached to the cable.Walter Hefti: ''Schienenseilbahnen in aller Welt. Schiefe Seilebenen, Standseilbahnen, Kabelbahnen.'' Birkhäuser, Basel 1975, (in German) In other forms, the cars attach and detach to the cable at the ends of the cable railway. Some cable railways are not steeply graded - these are often used in quarries to move large numbers of wagons between the quarry to the processing plant. History The oldest extant cable railway is probably the Reisszug, a private line pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Button Lift
A button is a fastener that joins two pieces of fabric together by slipping through a loop or by sliding through a buttonhole. In modern clothing and fashion design, buttons are commonly made of plastic but also may be made of metal, wood, or seashell. Buttons can also be used on containers such as wallets and bags. Buttons may be sewn onto garments and similar items exclusively for purposes of ornamentation. In the applied arts and craft, a button can be an example of folk art, studio craft, or even a miniature work of art. In archaeology, a button can be a significant artifact. History Buttons and button-like objects used as ornaments or seals rather than fasteners have been discovered in the Indus Valley civilization during its Kot Diji phase (c. 2800–2600 BC). Buttons as apparel have been found at sites of the Catacomb culture, Russia (2500-1950 BC), at the Tomb of the Eagles, Scotland (2200–1800 BC), and at Bronze Age sites in China (c. 2000–1500 BC) and Ancie ...

People Mover
A people mover or automated people mover (APM) is a type of small-scale automated guideway transit system. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks. The term was originally applied to three different systems, developed roughly at the same time. One was Skybus, an automated mass transit system prototyped by the Westinghouse Electric Corporation beginning in 1964. The second, alternately called the People Mover and Minirail, opened in Montreal at Expo 67. Finally the last, called PeopleMover or WEDway PeopleMover, was an attraction that was originally presented by Goodyear Tire and Rubber Company and that opened at Disneyland in 1967. The term "people mover" currently describes technologies such as monorail, rail tracks and maglev. Propulsion may involve conventional on-board electric motors, linear motors or cable traction. Generally speaking, larger APMs are referred to by oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detachable Chairlift
A detachable chairlift or high-speed chairlift is a type of passenger aerial lift, which, like a fixed-grip chairlift, consists of numerous chairs attached to a constantly moving wire rope (called a ''haul rope'') that is strung between two (or more) terminals over intermediate towers. In contrast to the fixed-grip version, the chairs of a detachable chair lift detach from the haul rope for loading and unloading. The significance of ''detachable'' chairlift technology is primarily the speed and capacity. Detachable chairlifts move far faster than their fixed-grip brethren, averaging 1,000 feet per minute (11.3 mph, 18 km/h, 5.08 m/s) versus a typical fixed-grip speed of 500 ft/min (5.6 mph, 9 km/h, 2.54 m/s). Because the cable moves faster than most passengers could safely disembark and load, each chair is connected to the cable by a powerful spring-loaded cable grip which detaches at terminals, allowing the chair to slow considerably for ...

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 ...

Andrew Smith Hallidie
Andrew Smith Hallidie (March 16, 1836 – April 24, 1900) was an American entrepreneur who was the promoter of the Clay Street Hill Railroad in San Francisco. This was the world's first practical cable car system, and Hallidie is often therefore regarded as the inventor of the cable car and father of the present day San Francisco cable car system, although both claims are open to dispute. He also introduced the manufacture of wire rope to California, and at an early age was a prolific builder of bridges in the Californian interior. Early life Andrew Smith Hallidie was born Andrew Smith, later adopting the name Hallidie in honor of his uncle, Sir Andrew Hallidie. His birthplace is variously quoted as London in the United Kingdom. His mother, Julia Johnstone Smith, was from Lockerbie, Dumfriesshire and his father, Andrew Smith (a prolific inventor in his own right, responsible for inventing the first box door spring, a floor cramp and had an early patent for wire rope) was born ...

Field-replaceable Unit
A field-replaceable unit (FRU) is a printed circuit board, part, or assembly that can be quickly and easily removed from a computer or other piece of electronic equipment, and replaced by the user or a technician without having to send the entire product or system to a repair facility. FRUs allow a technician lacking in-depth product knowledge to isolate faults and replace faulty components. The granularity of FRUs in a system impacts total cost of ownership and support, including the costs of stocking spare parts, where spares are deployed to meet repair time goals, how diagnostic tools are designed and implemented, levels of training for field personnel, whether end-users can do their own FRU replacement, etc. Other equipment FRUs are not strictly confined to computers but are also part of many high-end, lower-volume consumer and commercial products. For example, in military aviation, electronic components of line-replaceable units, typically known as shop-replaceable units (SR ...
