peer agreement (net): +1contact head Explanation: Veja os textos abaixo "Originalmente, os pantógrafos eram apenas isto, um "pantógrafo" (instrumento de ampliação/redução de desenhos) em forma de losango com a canoa no topo, e a canoa possui duas faces de contato. Os sistemas mais modernos utilizam pantógrafos de apenas um braço – metade do formato original – um design mais limpo (Figura 12). " "Originally, pantographs were just that, a diamond-shaped "pantograph" with the contact head at the top. Two contact faces are normally provided. More modern systems use a single arm pantograph - really just half of the original shape - a neater looking design (photo above)."

arm Explanation: I'm fairly sure this refers to the articulated levers that hold the shoe (sapato) against the catenary wire. Old pantographs usually had dual arms (a diamond-shaped arrangement) but modern ones (as on the TGV in France) have single arms which less heavy and more responsive to changes in the height of the catenary. http://en.wikipedia.org/wiki/Pantograph_(rail) -------------------------------------------------- Note added at 3 hrs (2008-07-11 01:22:18 GMT) -------------------------------------------------- Re asker's note below: Of course it's not the arm that contacts the catenary. But your text does not suggest that 'canoa' refers to the part of the pantograph that contacts the catenary, does it? The text refers to 'canoa e sapata' - and it's the sapato/a that touches the catenary. Maybe 'canoa' refers to the (steel) top bar of the (single-arm) pantograph structure to which the (copper, graphite or other highly conductive material) 'sapata' is fixed. |

blade pantograph / single-arm pantograph Explanation: Sug. Creio que a canoa seja a parte, em forma de lâmina curva, que de fato entra em contato com a rede elétrica. - A pantograph is a device that collects electric current from overhead lines for electric trains or trams. The term stems from the resemblance to pantograph ... en.wikipedia.org/wiki/Pantograph_(rail) - 30k - utilização de 2 pantógrafos diminuindo o número de lâminas dos pantógrafos e a força de. contato da canoa na rede. Em testes verificaram que não ocorreram ... www.cbtu.gov.br/estudos/gpaa/14gpaa/sintese14reuniao.pdf -------------------------------------------------- Note added at 10 hrs (2008-07-11 08:39:39 GMT) -------------------------------------------------- Há um outro elemento, chamado de "bow collector" utilizado para fazer a transferência da energia dos fios para o trem. Busque no Google por esta expressão ou por " bow pantograph" |

collector head Explanation: I thought that 'contact head' was correct because of the reference given by Marlene but there is only that one reference. 'collector head' appears more frequently. Example sentence(s):
