Abstract
GARRA DE TESOURAS OPERADA POR QUATRO CABOS. Uma garra de tesouras operada por quatro cabos, compreendendo um par de alavancas de tesoura que são conectadas através de uma junção pivô para pivotar em torno de um eixo pivô, cada uma das alavancas de tesoura a qual inclui um casco de garra e uma conexão de cabo de içamento situada em um primeiro lado da alavanca com relação à junção pivô, e uma conexão de cabo de fechamento situada em um segundo lado da alavanca que é oposto com relação à junção pivô, de forma que em uso um cabo de içamento dedicado é fixado a cada alavanca no primeiro lado da alavanca, e um cabo de fechamento dedicado é fixado a cada alavanca no segundo lado da alavanca. Cada uma das alavancas de tesoura inclui uma roldana no segundo lado da alavanca, e cada uma das ditas roldanas arranjada como uma primeira roldana de fechamento e roldana de fechamento final, de forma que em uso cada um dos dois cabos de fechamento se estende em um único passe a partir de uma conexão de cabo de fechamento no segundo lado de uma alavanca através da roldana de fechamento no segundo lado da outra alavanca para partir a partir da garra e continuar para cima para um guindaste que porta a garra.
