Abstract

SE PRESENTA UN APARATO MONTACARGAS DE CABLE MEJORADO (10) QUE TIENE UNA RUEDA EXCENTRICA (22) MOVIBLEMENTE CONECTADA A UNA ARMADURA (50) PARA DESVIAR EL CABLE (12) EN UNA ACANALADURA CIRCUNFERENCIAL (58) EN LA RUEDA EXCENTRICA. MEDIOS DE DESVIACION SOBRE LA ESTRUCTURA COMPRIMEN EL CABLE EN LA ACANALADURA DE LA EXCENTRICA CON UNA CANTIDAD DE FUERZA QUE DEPENDE DE LA TENSION DEL CABLE. LA EXCENTRICA SE POSICIONA CON RELACION A LA ARMADURA COMO UNA FUNCION DE LA TENSION DEL CABLE DE TAL FORMA QUE A MAYOR TENSION EN EL CABLE, MAYOR FUERZA DE DESVIACION SOBRE EL CABLE. ADEMAS LOS MEDIOS DESVIADORES PUEDEN INCLUIR UNA PLURALIDAD DE RODILLOS (62, 94) PARA REGULAR LA FUERZA DE DESVIACION. UN MUELLE ENEBRADOR (142) PUEDE USARSE EN CONJUNCION CON LOS MEDIOS DESVIADORES PARA PERMITIR EL ENEBRADO DEL ELEVADOR CUANDO EL CABLE ESTA DESCARGADO. EL APARATO ELEVADOR OPTIMAMENTE INCORPORA CIERTAS VENTAJAS EN CUANTO A SEGURIDAD (124, 162). ESTAS INCLUYEN UN FRENO DE CABLE ACTIVADO Y LIBERADO DEPENDIENDO DE LA POSICION DE LA EXCENTRICA Y UN MOTOR DE PARADA COMO FUNCION DE LA SOBRE CARGA Y / O DESCARGA.AN IMPROVED CABLE TRUCK APPLIANCE (10) IS PRESENTED THAT HAS AN ECCENTRIC WHEEL (22) MOVABLY CONNECTED TO A ARMOR (50) TO DIVIDE THE CABLE (12) IN A CIRCUMFERENTIAL GUTTER (58) IN THE EXCENTRIC WHEEL. DEVIATION MEANS ON THE STRUCTURE COMPRESSES THE CABLE IN THE EXCENTRIC GUTTER WITH A QUANTITY OF FORCE DEPENDING ON THE TENSION OF THE CABLE. THE ECCENTRIC IS POSITIONED IN RELATION TO THE ARMOR AS A FUNCTION OF THE CABLE TENSION IN SUCH A WAY THAT THE MORE TENSION IN THE CABLE, THE MORE DEVIATION FORCE ON THE CABLE. IN ADDITION, THE DIVERTER MEANS MAY INCLUDE A PLURALITY OF ROLLERS (62, 94) TO REGULATE THE FORCE OF DEVIATION. A THREAD SPRING (142) MAY BE USED IN CONJUNCTION WITH DIVERTERS TO ALLOW LIFTING THREAD WHEN THE CABLE IS UNLOADED. THE LIFTING DEVICE OPTIMALLY INCORPORATES CERTAIN ADVANTAGES AS TO SAFETY (124, 162). THESE INCLUDE A CABLE BRAKE ACTIVATED AND RELEASED DEPENDING ON THE POSITION OF THE ECCENTRIC AND A STOPPING MOTOR AS A FUNCTION OF OVERLOAD AND / OR DISCHARGE.
