Abstract

Grúa torre de pluma abatible con elevación de pluma sin cable, estando la pluma (1) y la contrapluma (2) formando un conjunto en el que no se mueve una respecto a la otra sino conjuntamente como bloque, girando dicho conjunto en un punto de rotación (4), siendo el giro en el plano vertical el único giro que se permite con respecto a dicho punto de rotación (4), definiendo respecto a éste como parte delantera el lado donde se levanta la carga y que se sitúa en lado de la pluma (1), y parte trasera el lado de contrapeso (3), que se sitúa en la contrapluma (2), estando el accionador (7) unido en su parte inferior a la punta de torre (6) que se apoya en la torre (8) y en la parte superior al conjunto de pluma (1) y contrapluma (2) en su parte trasera con respecto al punto de rotación (4), de forma que, al levantar la pluma (1) con carga en alcance máximo, el accionador (7) esté trabajando a tracción.Luffing jib tower crane with jib elevation without cable, with the jib (1) and the counter jib (2) forming a set in which one does not move relative to the other but together as a block, said set rotating at a point of rotation (4), being the rotation in the vertical plane the only rotation that is allowed with respect to said point of rotation (4), defining with respect to it as the front part the side where the load is lifted and which is located on the side of the jib (1), and the rear part of the counterweight side (3), which is located in the counter-jib (2), with the actuator (7) attached at the bottom to the tower point (6) which rests on the tower (8) and the upper part of the jib (1) and counter-jib (2) assembly at the rear with respect to the rotation point (4), so that when lifting the jib (1) with load in maximum reach, the actuator (7) is working with traction.
