Abstract

SE PRESENTA UNA GRUA DE AGUILON EXTERIOR QUE COMPRENDE UNA PRIMERA SECCION DE AGUILON (1) Y UN AGUILON EXTERNO (2) QUE PUEDE PIVOTAR CON RELACION A LA PRIMERA SECCION DE AGUILON POR MEDIO DE UN CILINDRO HIDRAULICO (12) EN EL QUE UNO DE LOS EXTREMOS ESTA CONECTADO A LA PRIMERA SECCION DEL AGUILON MEDIANTE UNA PRIMERA ARTICULACION (13) Y EL EXTREMO OPUESTO ESTA CONECTADO AL AGUILON EXTERIOR (2) MEDIANTE UNA SEGUNDA ARTICULACION (14). ENTRE LOS DOS AGUILONES (1, 2), SE DISPONE AL MENOS UN DISPOSITIVO DE UNION (15) QUE ESTA CONECTADO A LA PRIMERA SECCION DEL AGUILON MEDIANTE UNA TERCERA ARTICULACION (16) Y AL AGUILON EXTERIOR (2) MEDIANTE UNA CUARTA ARTICULACION (17) QUE ESTA SEPARADA DE LA SEGUNDA ARTICULACION (14) Y DE LA TERCERA ARTICULACION (16), MAS ESPECIFICAMENTE, CON LA TERCERA ARTICULACION (16) SITUADA A UNA DISTANCIA MAYOR DE LA CUARTA ARTICULACION (17) QUE DE LA SEGUNDA ARTICULACION (14). POR MEDIO DEL DISPOSITIVO DE UNION (15), EL AGUILON EXTERIOR (2) PUEDE CONMUTAR DE PUNTOS DE ARTICULACION DE MANERA QUE PIVOTE DENTRO DE SU ALCANCE DE TRABAJO, ALREDEDOR DE UNA CUARTA ARTICULACION (17) QUE ESTA SITUADA A GRAN DISTANCIA DE LA ARTICULACION PRINCIPAL (3) DE LA PRIMERA SECCION DEL AGUILON, MIENTRAS, CUANDO PIVOTA HACIA Y DESDE SU POSICION DE BLOQUEO SOBRE EL LADO SUPERIOR DE LA PRIMERA SECCION DEL AGUILON, PIVOTA PARADO ALREDEDOR DE LA TERCERA ARTICULACION (16) QUE ESTA SITUADA CONSIDERABLEMENTE MAS CERCA DE LA ARTICULACION PRINCIPAL (3).
