Abstract

Grúa del tipo de montaje rápido, que comporta un mástil exterior articulado, por su base, sobre una plataforma giratoria y en el interior del cual es susceptible de deslizar un mástil interior que soporta, en su cabeza, un flecha distribuidora, siendo la estructura en celosía (integrada por los citados mástiles, interior y exterior) y la flecha, del tipo abatible, caracterizada porque el citada grúa comprende, en combinación, un cable trasero de retención y un cable de compensación, unidos por medio de pasadores a la plataforma antes de ser conectados a la parte posterior de un dispositivo de equilibrado, circulando el cable de compensación, entonces, sobre unas poleas para formar un aparejo en el interior de la estructura en celosía, antes de ser fijado a la cabeza del mástil exterior, mientras que la longitud de estos dos cables se ha previsto de modo que uno de los permanezca siempre tenso y mantega en la horizontal a la flecha durante las diferentes fases de puesta en pie, de izado telescópico, de sobrelevación y de montaje de la grúa.
