Title (EN) ROTARY TOWER CRANE
(FR) GRUE À TOUR
(DE) Turmdrehkran
Abstract:
(EN) The invention relates to a rotary tower crane with a tower (2), which carries a jib (3) and a counterjib (4), with a jib stay (9) being guided from a tower top (10) to the jib and to the counterjib. According to the invention the jib stay tensions only an inner jib portion, the length of which is less than 40% of the total length of the jib, and an outer portion, the length of which is more than 60% of the total length of the jib, forms an untensioned bending beam jib which comprises at least one jib piece which tapers in height and which is adjoined on the inner side by at least one jib part of greater height and on the outer side by a jib piece of smaller height.
(FR) L'invention concerne une grue à tour comprenant une tour (2) portant une flèche (3) et une contre-flèche (4), un système d'haubanage de flèche (9) étant guidé à partir d'une pointe (10) de la tour jusqu'à la flèche et jusqu'à la contre-flèche. Selon l'invention, ce système d'haubanage de flèche présente uniquement une section de flèche interne dont la longueur est inférieure à 40% de la longueur totale de la flèche, et une section de flèche externe dont la longueur est supérieure à 60% de la longueur totale de la flèche, de façon à former une flèche à poutre en porte-à-faux non haubanée comportant au moins une pièce de flèche allant en s'amincissant vers le haut à côté de la laquelle se trouvent, côté interne, au moins une pièce de flèche plus haute et, côté externe une pièce de flèche moins haute.
(DE) Turmdrehkran mit einem Turm (2), der einen Ausleger (3) und einen Gegenausleger (4) trägt, wobei von einer Turmspitze (10) eine Auslegerabspannung (9) zum Ausleger und zum Gegenausleger geführt ist. Erfindungsgemäß ist vorgesehen, dass die Auslegerabspannung nur einen inneren Auslegerabschnitt, dessen Länge weniger als 40% der Gesamtlänge des Auslegers beträgt, abspannt und ein äußerer Auslegerabschnitt, dessen Länge mehr als 60% der Gesamtlänge des Auslegers beträgt, einen unabgespannten Biegebalkenausleger bildet, der zumindest ein sich in der Höhe verjüngendes Auslegerstück aufweist, an das sich innenseitig zumindest ein Auslegerteil größerer Höhe und außenseitig ein Auslegerstück kleinerer Höhe anschließt.
