Abstract
ESTA GRUA REPLEGABLE, ESPECIALMENTE DE MASTIL TELESCOPICO (7), ESTA DOTADA DE UNA FLECHA DISTRIBUIDORA (11) ARTICULADA EN LA CUSPIDE DEL MASTIL (7) Y FORMADA POR DOS O TRES ELEMENTOS (12,13,14) ARTICULADOS ENTRE SI. UN CONJUNTO DE PUNTALES (16,36) Y DE TIRANTES (38) SUJETAN AL ELEMENTO DE PUNTA DE FLECHA O FLECHITA (14), EN EL CASO DE UNA FLECHA DE TRES ELEMENTOS, Y AL ELEMENTO DE PIEDE FLECHA (12), MIENTRAS QUE UN CABLE POSTERIOR DE RETENCION ENLAZA A LA CUSPIDE DEL PUNTAL POSTERIOR (16) CON UN CHASIS GIRATORIO, MANTENIENDO A LA FLECHA (11) EN EQUILIBRIO. LA GRUA CONSTA ASIMISMO DE UN CABLE MOTIRIZADO DE REPLEGADO Y DESPLEGADO DE LA FLECHA (61), QUE SE ENROLLA EN UN CABESTRANTE (60) Y UNE AL SEGUNDO ELEMENTO DE FLECHA (13) CON EL PIE DE FLECHA (12) MEDIANTE EL CONJUNTO DE PUNTALES (16,36), PASANDO POR LA CUSPIDE (20) DEL PUNTAL POSTERIOR (16) SITUADO SOBRE EL PIE DE FLECHA (11).THIS FOLDING CRANE, ESPECIALLY OF TELESCOPIC MAST (7), IS EQUIPPED WITH A DISTRIBUTING ARROW (11) ARTICULATED IN THE CUSP OF THE MAST (7) AND FORMED BY TWO OR THREE ELEMENTS (12,13,14) ARTICULATED BETWEEN THEM. A SET OF PROPS (16,36) AND BRACES (38) ATTACH THE ARROW OR ARROW POINT ELEMENT (14), IN THE CASE OF A THREE-ELEMENT ARROW, AND WHILE THE STONE IS ARROWED (12), WHILE A REAR RETENTION CABLE LINKS TO THE CUSP OF THE REAR PROP (16) WITH A ROTATING CHASSIS, KEEPING THE ARROW (11) IN BALANCE. THE CRANE ALSO CONSISTS OF A MOTORIZED CABLE OF WITHDRAWAL AND UNFOLDING OF THE ARROW (61), WHICH COILS IN A WINCH (60) AND JOINS THE SECOND ARROW ELEMENT (13) WITH THE FOOT OF THE ARROW (12) THROUGH THE ASSEMBLY OF PROPS (16,36), PASSING THROUGH THE CUSP (20) OF THE REAR PROP (16) LOCATED ON THE ARROW FOOT (11).
