Abstract

Perfeccionamientos en los equipos de manipulación de materiales, que incluyen un cuerpo de vehículo, un pescante soportado pivotantemente por un extremo en dicho cuerpo con un ariete fluido de pescante entre dicho cuerpo y dicho pescante para hacer pivotar dicho pescante y una unidad de manipulación de materiales montada pivotantemente en el extremo libre de dicho pescante por medio de un ariete fluido para la unidad, caracterizados porque el equipo comprende un brazo soportado en dicho cuerpo por un primer pasador de pivote con dicho pescante soportado en dicho brazo por medio de un segundo pasador de pivote espaciado de dicho primer pasador de pivote; medios de articulación entre dicho brazo y pescante, teniendo dichos medios de articulación un extremo conectado a dicho brazo por un tercer pasador de pivote espaciado de dichos pasadores primero y segundo de pivote y un extremo opuesto conectado a dicho pescante en una situación espaciada de dicho segundo pasador de pivote, estando conectado pivotantemente dicho ariete fluido para la unidad a dichos medios de articulación entre extremos opuestos de los mismos; y medios de guía entre dicho cuerpo y dicho pescante para guiar dicho pescante durante su movimiento pivotante.
