Join system between tower heads fixed in funicular cranes

摘要

Join system between tower heads fixed in funicular cranes.The heads (1-1') of the cranes are interconnected using at least one bar (2) with threaded ends that crosses the structure (4) of each head (1-1'), which, in turn, crosses a horizontal distribution beam (6) and receives a nut (12) at each end that acts on the aforementioned distribution beam (6) with a ball and socket joint (10) in between. In this way, when a movement is produced relative to the tower heads (1) the adaptation capacity of the ball and socket joint (10) (of at least 7 degrees) allows the bars (2) to adopt, at all times, an axial arrangement with the efforts that they are to support, thus eliminating the classic flexion efforts and the resulting fatigue that they generate.IMAGE
