Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO APLICABLE A UNA GRUA DE TORRE DE MASTIL TELESCOPICO DE TRES ELEMENTOS PROVISTA DE UNA ESCALERA TELESCOPICA (13) CONSTITUIDA A SU VEZ POR TRES ELEMENTOS (14, 15, 16) CADA UNO DE LOS CUALES LLEVA ASOCIADO UN ELEMENTO DE ESCALERA. EL ELEMENTO DE ESCALERA (15) ASOCIADO AL ELEMENTO DE MASTIL CENTRAL TIENE UNOS MONTANTES (26) DE PERFIL DENTADO QUE ENVUELVEN LOS MONTANTES (22, 24) DE LOS OTROS DOS ELEMENTOS DE ESCALERA (14, 16). LA CABINA O EL ELEMENTO MOVIL QUE HAYA DE GUIARSE A LO LARGO DE LA ESCALERA (13) COMPRENDE UN BASTIDOR DE GUIA CUYA ESTRUCTURA (32) LLEVA PRIMEROS RODAMIENTOS DE GUIA (33, 34) SITUADOS FRENTE A LAS CARAS LATERALES DERECHA E IZQUIERDA DE LA ESCALERA (13) Y OTROS RODILLOS DE GUIA (37 A 42) QUE ABRAZAN DOS A DOS LOS MONTANTES (22, 24, 26) DE LOS ELEMENTOS DE ESCALERA (14, 15, 16) Y QUE SE ABREN PASO A LO LARGO DE LAS PARTES CONCAVAS (27) DE LOS MONTANTES (26) DEL ELEMENTO DE ESCALERA (15).THE INVENTION REFERS TO A DEVICE APPLICABLE TO A THREE-ELEMENTED TELESCOPIC MASTIL TOWER CRANE PROVIDED WITH A TELESCOPIC STAIRCASE (13) CONSTITUTED ONCE BY THREE ELEMENTS (14, 15, 16) EACH OF WHICH IT CARRIES AN ELEMENT STAIRCASE THE STAIRCASE ELEMENT (15) ASSOCIATED WITH THE CENTRAL MASTIL ELEMENT HAS STITCHED PROFILES (26) OF WINDING PROFILE WRAPPING UP THE ASSEMBLIES (22, 24) OF THE OTHER TWO STAIRS ELEMENTS (14, 16). THE CABIN OR THE MOBILE ELEMENT TO BE GUIDED THROUGH THE STAIRCASE (13) INCLUDES A GUIDE FRAME WHOSE STRUCTURE (32) CARRIES FIRST BEARING BEARINGS (33, 34) SITUATED AGAINST THE RIGHT AND LEFT SIDE FACES LADDER (13) AND OTHER GUIDE ROLLERS (37 TO 42) THAT EMBRACE TWO TO TWO THE MOUNTS (22, 24, 26) OF THE LADDER ELEMENTS (14, 15, 16) AND THAT OPEN PASS THROUGHOUT THE CONCAVAS PARTS (27) OF THE ASSEMBLIES (26) OF THE STAIRCASE ELEMENT (15).
