Unterburg Trolleybus Turntable
The Unterburg trolleybus turntable (german: Drehscheibe Unterburg) is a disused turntable for trolleybuses in the Solingen district Burg an der Wupper. The facility was regularly used by trolleybus line 683, operated by the Stadtwerke Solingen (SWS), until 15 November 2009, but is preserved in working condition. The turntable is the last of only four turntables of this type in the world. Two more were located in Great Britain: the Christchurch trolleybus turntable (1936 to 1969) and the Longwood trolleybus turntable at Huddersfield (1939 to 1940). The fourth trolleybus turntable, in Guadalajara, Mexico, was in use from 1982 to 1983 and from 1985 to 1988. Description The turning process lasts 45 seconds and is always carried out without passengers on board. The turntable is remotely operated by the driver from an adjoining control house. The trolley poles are lowered manually before starting the rotation and are reattached to the trolley wires afterwards, with the aid of so-c ...

Wupper
The Wupper is a right tributary of the Rhine in the state of North Rhine-Westphalia, Germany. Rising near Marienheide in western Sauerland it runs through the mountainous region of the Bergisches Land in Berg County and enters the Rhine at Leverkusen, south of Düsseldorf. Its upper course is called the Wipper. Both names are related to "weave", and refer to the twisting course. On its course of about , the Wupper passes through the city of Wuppertal where the suspension railway runs for above the river. It is crossed by the highest railway bridge in Germany near Müngsten, between Remscheid and Solingen. A few kilometers further down, Burg Castle is located on a hill overlooking the river. Hydropower From the 15th century, the Wupper and its numerous streams gave birth to hundreds of workshops, mills and factories on their banks. Originally water was used for dying, bleaching and washing canvas and cloth, later it was used to power machines or transport waste. The Wupper t ...

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 ...

Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, World War 1, Supermarine Nighthawk, an anti-Zeppelin night fighter.Andrews and Morgan 1987, p. 21.

Carrosserie Hess
Carrosserie HESS AG is a bus, trolleybus and commercial vehicle manufacturer based in Bellach, Switzerland. Their products can be found operating in several countries, including the United States and Canada. History The company was founded in 1882, when Heinrich Hess set up business in Solothurn to build customised car bodies. The company first began building buses in 1919, and production reverted to aluminium products in 1933. It produced its first trolleybuses in 1940 for the Swiss cities of Basel and Biel/Bienne. In 1961, it commenced building of articulated vehicles, some of which were supplied to operators in the United States and Canada in 1975. The company soon began to expand, and businesses were set up in Portugal and Australia in 1957 and 1978 respectively. The U.S. business was set up in 1996. The company began production of low-floor buses and trolleybuses in 1991, and in 2003 built its first double-articulated trolleybuses. Products Buses *N UB 2-2: A low-floor, tw ...

Rigid Bus
A rigid bus (either a motor bus or trolleybus) is a vehicle used in public transportation services with a single, rigid chassis. A bus of this type is to be contrasted with an articulated or bi-articulated bus, which will have two or more rigid sections linked by a pivoting joint, also with a trailer bus, which is formed out of a bus bodied semi-trailer pulled by a conventional tractor unit. The term "rigid bus" is used mainly in British English and Australian English and usually only when distinguishing such buses from articulated buses, such as describing a fleet that includes both types. In the case of two-axle buses, which must be single-chassis, rigid vehicles, British English often refers to such vehicles as "two-axle" buses, only using the term "rigid" when referring to vehicles with three or more axles, which can be either rigid or articulated. The term "rigid bus" is not used in American English, where the distinction is commonly made using the term "non-articulated" ...

MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg-Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hüttengewerks ...

Articulated Bus
An articulated bus, also referred to as a banana bus, bendy bus, tandem bus, vestibule bus, wiggle wagon, stretch bus, or an accordion bus, (either a motor bus or trolleybus) is an articulated vehicle used in public transportation. It is usually a single-decker, and comprises two or more rigid sections linked by a pivoting joint (articulation) enclosed by protective bellows inside and outside and a cover plate on the floor. This allows a longer legal length than rigid-bodied buses, and hence a higher passenger capacity (94–120), while still allowing the bus to maneuver adequately. Due to their high passenger capacity, articulated buses are often used as part of bus rapid transit schemes, and can include mechanical guidance. Articulated buses are typically long, in contrast to standard rigid buses at long. The common arrangement of an articulated bus is to have a forward section with two axles leading a rear section with a single axle, with the driving axle mounted on e ...

Hand Crank
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning Wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starting Han ...

Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the is often defined to be the smallest such distance. Both quantities can be calculated efficiently using rotating calipers. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all ...

Circle
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius. Usually, the radius is required to be a positive number. A circle with r=0 (a single point) is a degenerate case. This article is about circles in Euclidean geometry, and, in particular, the Euclidean plane, except where otherwise noted. Specifically, a circle is a simple closed curve that divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a '' disc''. A circle may also be defined as a special ki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
