sliding bow Explanation: link http://www.ansaldoenergia.com/PDF/GRMERCI.pdf page 3 archetto (del pantografo) sliding bow lo trovi anche in altre kudoz -------------------------------------------------- Note added at 13 ore (2012-06-24 08:01:24 GMT) -------------------------------------------------- qui trovi spiegazioni: http://en.wikipedia.org/wiki/Trolley_pole However, on most railway vehicles using overhead wire, the trolley pole has given way to the **bow collector** or, later, the **pantograph**, a folding metal device that presses a wide contact pan against the overhead wire. While more complex than the trolley pole, the pantograph has the advantage of being almost free from dewiring, being more stable at high speed, and being easier to raise and lower automatically. Also, on double-ended trams, they eliminate the need to manually turn the trolley pole when changing direction. The use of pantographs (or bow collectors) exclusively also eliminates the need for wire frogs (switches in the overhead wiring) to make sure the pole goes in the correct direction at junctions. http://en.wikipedia.org/wiki/Bow_collector Advantages and Modern Usage The bow collector has fewer moving parts than the trolley pole, but is heavier and sometimes more complicated to construct. The construction of overhead wires for bow collectors is simpler than trolley pole wiring. As bow collectors do not have revolving mountings, the collector cannot jump off the wire or follow the wrong one at intersections, as trolley poles sometimes do. Thus overhead 'frogs' and guides for trolley poles are not necessary with bow collectors. Bow collectors are, however, much noisier than trolley poles. The overhead wires for bow collectors are stretched tighter than for trolley poles, and straight sections are 'staggered', that is, the wire does not run completely straight down the centreline of the track, but rather zig-zags slightly across a small distance. This distributes wear across the bow collector's collector plate, and extends the collector's life. In addition to some vintage tramways, bow collectors are still used in some tram systems in the former Soviet Union, e. g., in Kazan, Minsk, and Dzerzhinsk. They are also used by the Snaefell Mountain Railway on the Isle of Man. may be bow collector fits your context better.

Buenos dias y bueno trabajo. |
