Abstract

SE DESCRIBE UN ENSAMBLAJE (36,82,114) DE MANTENIMIENTO DE UN ALA DE CONTROL CRUCIFORME (10) QUE INCLUYE UN CARRO (38) CON UN PRIMER Y SEGUNDO BRAZO DE CRUCE (40,42) CADA UNO CON UNA RANURA GENERALMENTE EN FORMA DE U (50,60) PARA RECIBIR LA PUNTA DEL ALA. EL PRIMER BRAZO DE CRUCE INCLUYE UN CONMUTADOR DE BLOQUEO PARA FIJAR RIGIDAMENTE EL SOPORTE A LA PUNTA DEL ALA. EL SEGUNDO BRAZO INCLUYE UNA HERRAMIENTA (68,94) SITUABLE ADYACENTE A UNA APERTURA DE RODILLO (26) EN UNO DE LOS CUATRO PANELES SELECCIONADO (12-18) DEL ALA. LA HERRAMIENTA SE COLOCA SOBRE EL SEGUNDO BRAZO A UNA PROFUNDIDAD PREDETERMINADA, A UN RADIO DE ACCION LATERAL PREDETERMINADO DESDE EL PRIMER BRAZO, DE FORMA QUE AL MONTAR EL CARRO SOBRE LA PUNTA DEL ALA Y AL CONMUTAR EL CONMUTADOR, LA HERRAMIENTA SE ALINEA VERTICAL Y LATERALMENTE CON EL CENTRO DE LA APERTURA DE RODILLO PANEL(26). DE UNA FORMA, LA HERRAMIENTA (68) ES EFECTIVA PARA ROMPER EL RODILLO DESDE LA APERTURA PANAL SIN DAÑAR EL PANAL, Y DE OTRA FORMA ES EFECTIVA PARA INSTALAR UNA ARANDELA ESPACIADORA DE REEMPLAZO(84) EN LA APERTURA.
