Title
(EN) AN EXTENSION YOKE FOR SELF-HOISTING CRANE, A SELF-HOISTING WIND TURBINE CRANE WITH AN EXTENSION YOKE, AND USE OF AN EXTENSION YOKE
(FR) CULASSE D'EXTENSION POUR GRUE À AUTO-LEVAGE, GRUE À TURBINE ÉOLIENNE À AUTO-LEVAGE DOTÉE D'UNE CULASSE D'EXTENSION, ET UTILISATION D'UNE CULASSE D'EXTENSION
Abstract
(EN) An extension yoke (1), a self-hoisting wind turbine crane (5) with such a yoke a method of using such a yoke are disclosed. The yoke comprises a frame structure comprising a lifting portion (2) and a load transfer portion (3), forming an obtuse angle with each other, and at least one crane attachment element (4) positioned between the load transfer portion and the lifting portion, said at least one crane attachment element being configured for establishing a pivot connection to a crane. The lifting portion comprised a load attachment element (2) and the load transfer portion comprise at least one load transfer element (33), said load transfer element being configured for transferring compressive force by pressing against a reception surface (52) of the crane and for moving in relation to the reception surface. The frame structure may comprise at least two substantially parallel longitudinal beams (12a, 12b), at least one cross-beam (13), and/or at least one stabilisation element (12), and the crane attachment element may comprise a pulley block reception element.
(FR) Culasse d'extension (1), grue à turbine éolienne à auto-levage (5) dotée d'une telle culasse et procédé d'utilisation d'une telle culasse. La culasse comprend une structure de cadre comprenant une partie de levage (2) et une partie de transfert de charge (3), formant un angle obtus l'une avec l'autre, et au moins un élément de fixation de grue (4) positionné entre la partie de transfert de charge et la partie de levage, ledit au moins un élément de fixation de grue étant conçu pour établir une liaison pivot avec une grue. La partie de levage comprend un élément de fixation de charge (2) et la partie de transfert de charge comprend au moins un élément de transfert de charge (33), ledit élément de transfert de charge étant configuré pour transférer une force de compression par pression contre une surface de réception (52) de la grue et pour se déplacer par rapport à la surface de réception. La structure de cadre peut comprendre au moins deux poutres longitudinales sensiblement parallèles (12a, 12b), au moins une traverse (13) et/ou au moins un élément de stabilisation (12), et l'élément de fixation de grue peut comprendre un élément de réception de blocage de poulie.
