Tank Transporter
A tank transporter is a combination of a heavy tractor unit or a ballast tractor and a mating Trailer (vehicle)#Full trailer, full trailer, hydraulic modular trailer or semi-trailer (typically of the Lowboy (trailer), "lowboy" type), used for transporting tanks and other armoured fighting vehicles. Some also function as tank recovery vehicles, the tractors of which may be armoured for protection in combat conditions. Used on roads, tank transporters reduce the wear and tear on Continuous track, tracks and the other components of the powertrains of tracked vehicles. They also Fuel efficiency, conserve fuel, are less damaging of road surfaces, and reduce tank crew fatigue. Overall, they are more efficient at moving tanks at higher speeds and longer distances than the tanks themselves. Chassis designs Three chassis designs have been used, generally in this order over time as loads became heavier, although there are exceptions. Rigid chassis The lighter tanks of World War I and ...

''The'' is a grammatical Article (grammar), article in English language, English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the Most common words in English, most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a con ...

Meknès - Défilé Des Blindés
Meknes (, ) is one of the four Imperial cities of Morocco, located in northern central Morocco and the sixth largest city by population in the kingdom. Founded in the 11th century by the Almoravids as a military settlement, Meknes became the capital of Morocco during the reign of Sultan Ismail Ibn Sharif (1672–1727), son of the founder of the Alaouite dynasty. Sultan Ismail created a massive imperial palace complex and endowed the city with extensive fortifications and monumental gates. The city recorded a population of 632,079 in the 2014 Moroccan census. It is the seat of Meknès Prefecture and an important economic hub in the region of Fès-Meknès. Etymology Meknes is named after an Amazigh (Berber) tribe historically known as the Miknasa ( in Amazigh languages). History Early history (8th–16th centuries) Volubilis, a major Roman-era settlement in Morocco and one of its early urban centres, is located near the site of the current city of Meknes. The current city and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingpin (automotive Part)
The kingpin (also king-pin, king pin and k pin) is the main wiktionary:pivot, pivot in the steering mechanism of a automobile, car or other vehicle. The term is also used to refer to part of a fifth wheel coupling apparatus for a Semi truck, semi and its Trailer (vehicle), trailer or other load. History Originally, with the 'turntable' steering of horse-drawn wagons, this was a single pin on which the moveable axle was pivoted beneath the wagon's frame. This located the axle from side to side, but the weight of the wagon was carried on a circular wooden ring turntable surrounding this. Similar centre pivot steering was used by steam traction engines, the kingpin being mounted on the 'perch bracket' beneath the boiler. Some early cars also used centre pivot steering, although it became apparent that it was unsuitable for their increasing speeds. Ackermann steering separates the steering movement into two pivots, one near the hub of each front wheel. The beam axle between them re ...

Ackermann Steering Geometry
The Ackermann steering geometry (also called Ackermann's steering trapezium) is a geometric arrangement of linkages in the steering of a car or other vehicle A vehicle () is a machine designed for self-propulsion, usually to transport people, cargo, or both. The term "vehicle" typically refers to land vehicles such as human-powered land vehicle, human-powered vehicles (e.g. bicycles, tricycles, velo ... designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. It was invented by the German carriage builder Georg Lankensperger in Munich in 1816, then patented by his agent in England, Rudolph Ackermann (1764–1834) in 1818 for horse-drawn carriages. Erasmus Darwin may have a prior claim as the inventor dating from 1758. He devised his steering system because he was injured when a carriage tipped over. Advantages The intention of Ackermann geometry is to avoid the need for tyres to slip sideways when foll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre Of Gravity
In physics, the center of mass of a distribution of mass in space (sometimes referred to as the barycenter or balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. For a rigid body containing its center of mass, this is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion. In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortoise (tank)
The Tortoise heavy assault tank (A39) was a British heavy assault gun tank design developed during the Second World War, but never put into mass production. It was developed for the task of clearing heavily fortified areas such as the Siegfried Line and as a result favoured armour protection over mobility. Although heavy, at 78 tons, and not readily transported, it was considered reliable and a good gun platform. Only a few prototypes of the Tortoise had been produced by the end of the war. After testing was complete, one was retained for preservation and the others disposed of. Development In the early part of 1943, the Allied forces anticipated considerable resistance in the projected future invasion of Europe, with the enemy fighting from heavily fortified positions such as the Siegfried Line. As a result, a new class of vehicles emerged, in the shape of assault tanks, which placed maximum armour protection at a higher priority than mobility. Initially, work was concent ...

Tank Recovery Unit T3 Including Dart Truck Tractor T13 And Trailer T28
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, and ...

Double Heading
In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-heading involves the use of multiple locomotives and so on. Double heading is most common with steam locomotives, but is also practised with diesel locomotives. It is not strictly the same practice as two or more diesel or electric locomotives working ' in multiple' (or 'multiple-working'), where both (or all) locomotives are controlled by a single driver in the cab of the leading locomotive. Advantages Double heading is practised for a number of reasons: * In the UK it was usually to gain traction on steep inclines, twice the amount of driven wheels – twice the amount of grip. * The need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, or a combination of the tw ...

Drawbar (haulage)
A drawbar is a solid coupling between a hauling vehicle and its hauled load. Drawbars are in common use with rail transport; road trailers, both large and small, industrial and recreational; and agricultural equipment. Agriculture and horse-drawn vehicles Agricultural equipment is hauled by a tractor-mounted drawbar. Specialist agricultural tools such as ploughs are attached to specialist drawbars which have functions in addition to transmitting tractive force. This was partly made redundant with Ferguson's development of the three-point linkage in his famous TE20. A wooden drawbar extends from the front of a wagon, cart, chariot or other horse-drawn vehicles to between the horses. A steel drawbar attaches a three-point hitch or other farm implement to a tractor. Road A drawbar is a towing or pushing connection between a tractive vehicle and its load. Light vehicles On light vehicles, the most common coupling is an A-frame drawbar coupled to a 1 7/8 inch or 50 mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortoise Tank On Tow BAOR 1948
Tortoises ( ) are reptiles of the family Testudinidae of the order Testudines (Latin for "tortoise"). Like other turtles, tortoises have a shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodira, they retract their necks and heads directly backward into the shell to protect them. Tortoises can vary in size with some species, such as the Galápagos giant tortoise, growing to more than in length, whereas others like the Speckled cape tortoise have shells that measure only long. Several lineages of tortoises have independently evolved very large body sizes in excess of , including the Galapagos giant tortoise and the Aldabra giant tortoise. They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. Tortoises are the longest-living land animals in the world, although the longest-living species of tortoise is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
