Abstract

Un brazo elevador telescópico (1) para máquinas autopropulsadas (10) como elevadores, manipuladores telescópicos y similares, que comprende: al menos tres elementos tubulares (21, 22, 23, 24, 25, 26) con secciones decrecientes y telescópicamente conectadas entre sí, para definir una estructura de soporte capaz de moverse entre una configuración retraída, en el que dichos elementos tubulares (21, 22, 23, 24, 25, 26) se insertan uno dentro del otro, y una configuración alargada, en el que, al menos, dos elementos tubulares se extraen al menos parcialmente; un actuador hidráulico (4) asociado con dicha estructura de soporte (21, 22, 23, 24, 25, 26) y provisto de, al menos, tres elementos hidráulicos (41, 42, 43) conectados telescópicamente entre sí, cada uno de los cuales está conectado a un elemento tubular respectivo de la estructura de soporte; al menos cuatro de dichos elementos tubulares (21,22, 23, 24, 25, 26) y un órgano de transmisión del movimiento (3) que conecta, al menos, dos elementos tubulares y que comprende uno o más elementos flexibles y una o más poleas en las que dichos elementos se deslizan, dicho órgano (3) puede producir la extensión/retracción de un elemento tubular con respecto a otro elemento tubular, tras la extensión/retracción de ese otro elemento; y en el que dicho actuador hidráulico comprende un cilindro hidráulico telescópico (4) provisto de un barril (41) y, al menos, dos varillas (42, 43), definidas por los respectivos elementos hidráulicos; caracterizado porque el cilindro hidráulico (4) incluye: al menos una primera varilla (42) insertada de forma deslizante dentro del barril (41); al menos una primera cámara de activación (51) definida dentro del barril (41); al menos un canal extensible (50) para poner dicha primera cámara de activación en comunicación (51) con el exterior; al menos una segunda cámara de activación (52) definida dentro de la primera varilla (42); y al menos una primera cámara de retracción (53) definida entre el barril (41) y la primera varilla (42), que se comunica con la segunda cámara de activación (52); la primera cámara de activación (51), la segunda cámara de activación (52) y la primera cámara de retracción (53) que están adaptadas para permitir la extensión/retracción recíproca del barril (41) y de la primera varilla (42), tras la entrada/salida de un fluido de trabajo a través de dicho canal telescópico (50).
