Abstract
Sistema de unión entre cabezas de torres fijas en grúas de blondín. Las cabezas (1-1'') de las torres están relacionadas entre sí a través de al menos una barra (2), de extremos (3) roscados, que atraviesa la estructura (4) de cada cabeza (1-1''), atraviesa a su vez una viga horizontal de reparto (6), y recibe en cada extremo a una tuerca (12) que actúa sobre la citada viga de reparto (6) con interposición de una rótula (10). De ésta manera cuando se produce un desplazamiento relativo de las cabezas (1) de las torres, la capacidad de adaptación de las rótulas (10), de cómo mínimo 7°, permite que las barras (2) adopten en todo momento una disposición de axialidad con los esfuerzos que han de soportar, eliminando así los clásicos esfuerzos de flexión y la consecuente fatiga que estos generan.Joint system between fixed tower heads in blondin cranes. The heads (1-1 '') of the towers are related to each other through at least one bar (2), with threaded ends (3), which crosses the structure (4) of each head (1-1 '' ), in turn, passes through a horizontal distribution beam (6), and receives at each end a nut (12) that acts on said distribution beam (6) with interposition of a ball joint (10). In this way when a relative displacement of the heads (1) of the towers occurs, the adaptability of the ball joints (10), of at least 7 °, allows the bars (2) to adopt at all times an arrangement of axiality with the efforts that have to bear, thus eliminating the classic bending efforts and the consequent fatigue that they generate.
