Abstract

Patente de Invenção: <B>"EXTRATOR DE GRAMPO HIDRáULICO COM GARRAS MóVEIS FRICCIONALMENTE RETARDADAS E PERFìS FRONTAIS DA GARRA DE BLOQUEIO"<D>. Um extrator de grampo hidráulico compreendendo uma armação com uma calha, uma seção de acionamento hidráulica conectadas a armação e uma seção de contactar o grampo conectada a seção de acionamento hidráulica e localizada movelmente na calha. O aperfeiçoamento compreende a seção de contato de grampo compreendendo duas garras pivotadamente conectadas entre si e um sistema de fricção estendendo-se das garras e contactando os lados inferiores opostos da calha. As garras cada qual tem uma seção de garra de conctacto que, quando as garras estão em uma posição aberta, tem uma superfície traseira adjacente ao lado interno da calha para bloquear uma área entre a calha e a superfície traseira. As seções de garra têm substancialmente faces de fundo não encurvadas que, quando as garras estão na posição aberta, pode empurrar um grampo para fora de uma calha. As seções de garra são configuradas para evitar um grampo de ser captado entre a calha e as superfícies posteriores das seções de garra.
