Abstract

SE MONTA UN SISTEMA DE UNION PARA MAQUINAS DE CARGA EN UN BRAZO ELEVADOR DOBLE (14) QUE SOPORTA UNA HORQUILLA ELEVADORA DE PALETAS O UNA CUBETA (22) EN LOS EXTREMOS DE LOS BRAZOS ELEVADORES. EL SISTEMA ESTA DISEÑADO DE FORMA QUE AL USAR UNA CUBETA O UNA HORQUILLA, EL SISTEMA DE UNION ASEGURA QUE DICHA CUBETA U HORQUILLA TOMARAN UNA POSICION ANGULAR SUSTANCIALMENTE DESEADA A MEDIDA QUE SE ELEVAN Y BAJAN, SIN NECESIDAD DE HACER AJUSTES AL CILINDRO DE VUELCO A MEDIDA QUE SE ELEVAN LA CUBETA O LA HORQUILLA.
