Abstract

EN UNA CARRETILLA ELEVADORA, PREFERENTE MANDADA POR UN PERTIGO,CON UNA UNIDAD DE ACCIONAMIENTO PRETENSADA CARGADA SOBRE MUELLES EN SENTIDO VERTICAL (3) ESTA DIRIGIDA MEDIANTE UN REMOLQUE DE PALANCA DE PARALELOGRAMO (41, 42, 44) A UN BASTIDOR (1) NO ELEVABLE DEL ELEVADOR COMPENSABLE EN LA LATURA. PARA LA ADAPTACION CONTINUADA DE LA PRESION DE SERVICIO A LAS RELACIONES DE CARGA UTIL HAY AL MENOS UN CILINDRO DE CARRERA (45) DE LA HIDRAULICA DE FUNCIONAMIENTO PARA LA CARRETA DE BASE COLOCADO DIRECTAMENTE ENTRE EL BASTIDOR ELEVABLE (49) Y EL REMOLQUE DE PALANCA PARALELOGRAMO (41, 42, 44) Y AL MISMO TIEMPO ASENTADO POR SU PARTE INFERIOR EN UNA PALANCA TRASVERSAL HORIZONTAL(42). LA POTENCIA DE LA CARRERA EN SENTIDO CONTRARIO A LA POTENCIA DE APOYO DEL CILINDRO DE CARRERA (45) SE DESCOMPONE CORRESPONDIENDO A UNA RELACION DE PALANCA (47, 48) CON LO QUE UN COMPONENETE DE POTENCIA ES TOMADA POR EL BASTIDOR (1) NO ELEVABLE Y LOS OTROS COMPONENTES DE POTENCIA SON TRANSMITIDOS MEDIANTE UN BRAZO DE PALANCA (47) DIRECTAMENTE SOBRE LA RUEDA DE ACCIONAMIENTO 5 DE LA UNIDAD DE ACCIONAMIENTO 3 PARA DE ESTA FORMA TENER EL MOMENTO PRECISO DE ACCIONAMIENTO Y FRENO. PARA QUE LA UNIDAD DE ACCIONAMIENTO (3) PUEDA COMPENSARSUELOS NO LISOS INCLUSO CUANDO EL ELEVADOR ESTA ABAJO, UN EMBOLO DE CARRERA (50) DEL CILINDRO DE CARRERA (45) ESTA EQUIPADO CON UNA MARCHA LIBRE (52) COMO CARRERA RESULTANTE.
