Abstract

Grúa plegable del género en el cual el mástil preferiblemente de tipo telescópico está montado articuladamente sobre un soporte llevado por el pedestal de la grúa, caracterizada porque la flecha y la contraflecha pueden ser plegadas en posición horizontal sobre el mástil replegado asimismo en horizontal y porque los aparatos de elevación utilizados al plegar o al levantar la grúa, puesto aparte el movimiento telescópico eventual del mástil, están constituidos exclusivamente por tres cables independientes accionados cada uno de ellos por un torno, a saber el cable de mando del desplazamiento del carretón, un cable dispuesto en forma de aparejo que une el pedestal de la grúa con la extremidad inferior del mástil, y el cable de elevación de cargas cuyo gancho está enganchado en un punto del pedestal durante toda la operación.
