Impact Attenuator
An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle Traffic collision, collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy. They may also be designed to redirect the vehicle away from the hazard or away from roadway machinery and workers. Impact attenuators are usually placed in front of fixed structures near highways, such as Gore (road), gore points, Traffic barrier, crash barrier introductions, or overpass supports. Temporary versions may be used for road construction projects. Operation Impact attenuators are designed to absorb the colliding vehicle's kinetic energy to bring it to a stop safely. If no impact attenuator is present, a vehicle which strikes a rigid roadside object will suddenly stop. A person inside will promptly collide with the interior of the vehicle, and that person's inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snow Plow
A snowplow (also snow plow, snowplough or snow plough) is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes. Although this term is often used to refer to vehicles mounting such devices, more accurately they are known as winter service vehicles, especially in areas that regularly receive large amounts of snow every year, or in specific environments such as airfields. In other cases, pickup trucks and front end loaders are outfitted with attachments to fulfill this purpose. Some regions that do not frequently see snow may use graders to remove compacted snow and ice off the streets. Snowplows can also be mounted on rail cars or locomotives to clear railway tracks. Usage A snowplow works by using a blade to push snow to the side to clear it from a surface. Modern plows may include technology to make it easier to perform the work and stay on the road. These include Global Positioning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buffer (rail Transport)
A buffer is a part of the buffers and chain coupler system used on the railway systems of many countries, among them most of those in Europe, for attaching railway vehicles together (in North America, rolling stock instead has draft gear built into the couplers). Description Fitted at the ends of the vehicle frames on the buffer beam, one at each corner, the buffers are projecting, shock-absorbing pads which, when vehicles are coupled, are brought into contact with those on the next vehicle. The buffer itself comprises the buffer plates which take the impact. The draw chain used between each pair of vehicles includes a screw which is tightened after coupling to shorten the chain and keep the buffers pressed together. Such is known as a 'screw coupling'. Historically, coupling chains were no more than that, a short length of heavy chain (typically three links long) with no adjustment. These would result in a 'loose-coupled train' in which the buffers of adjacent vehicles wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Salt Lake Tribune
''The Salt Lake Tribune'' is a newspaper published in the city of Salt Lake City, Utah. The ''Tribune'' is owned by The Salt Lake Tribune, Inc., a non-profit corporation. The newspaper's motto is "Utah's Independent Voice Since 1871." History 19th century A successor to ''Utah Magazine'' (1868), ''The Salt Lake Tribune'' was founded as the ''Mormon Tribune'' by a group of businessmen led by former members of the Church of Jesus Christ of Latter-day Saints (LDS Church) William Godbe, Elias L.T. Harrison and Edward Tullidge, who disagreed with the church's economic and political positions. After a year, the publishers changed the name to the ''Salt Lake Daily Tribune and Utah Mining Gazette'', but soon after that, they shortened it to ''The Salt Lake Tribune''. Three Kansas businessmen, Frederic Lockley, George F. Prescott and A.M. Hamilton, purchased the company in 1873 and turned it into an independent newspaper which consistently backed the local Liberal Party. Sometimes v ...

Guard Rail
Guard rails, guardrails, railings or protective guarding, in general, are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or Motif (visual arts), motifs particularly on and beside gates. High security railings (particularly if in flat metal then a type of palisade) may instead feature jagged points and most metals are well-suited to anti-climb paint. A handrail is less restrictive on its own than a guard rail and provides support. Public safety Many public spaces are fitted with guard rails as a means of protection against accidental falls. Any abrupt change in elevation where the higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strafing
Strafing is the military practice of attacking ground targets from low-flying aircraft using aircraft-mounted automatic weapons. Less commonly, the term is used by extension to describe high-speed firing runs by any land or naval craft such as fast boats, using smaller-caliber weapons and targeting stationary or slowly-moving targets. Etymology The word is an adaptation of German ''strafen'' (), to punish, specifically from the humorous adaptation of the German anti-British slogan '' Gott strafe England'' (May God punish England), dating back to World War I. Description Guns used in strafing range in caliber from machine guns, to autocannon or rotary cannon. Although ground attack using automatic weapons fire is very often accompanied with bombing or rocket fire, the term "strafing" does not specifically include the last two. The term "strafing" can cover either fixed guns, or aimable (flexible) guns. Fixed guns firing directly ahead tend to be more predominant on ...
