    摘要: Le dispositif d'articulation (10) comprend un axe d'articulation (14), qui s'étend entre une tôle inférieure (12) et une tôle supérieure (13) du châssis (2), en traversant la région d'extrémité du bras d'appui (9). L'axe (14) présente, dans sa partie inférieure, un épaulement annulaire (21) qui délimite une tête inférieure (22) de diamètre plus élevé. Des moyens (25 à 30) de positionnement, de traction vers le haut et de blocage en rotation sont prévus dans la partie supérieure (23) de l'axe (14) et au niveau de la tôle supérieure (13). En exerçant une traction (T) sur l'axe (14), celui-ci entraîne le bras (9) vers le haut par l'intermédiaire de son épaulement (21), et rapproche ainsi la surface supérieure (31) du bras (9) et la surface inférieure (32) de la tôle supérieure (13) du châssis (2).
    Ce dispositif est applicable aux engins de levage, en particulier aux grues à tour.

    摘要: An extendible crane boom comprises a number of telescopic boom sections, which are each composed of a tube and a holder mounted at an outer end of the tube and serving as an attachment for a double-acting hydraulic cylinder which serves to displace the individual telescopic boom section out of or into an immediately preceding boom section so as to extend and shorten, respectively, the crane boom in its entirety. The cylinder part (7) of each hydraulic cylinder is connected to the holder via a coupling comprising a screw joint having several screws, and a pair of cooperating male and female members (11, 9), one of which has a part-spherical surface (18) which faces the other and which, when the screw joint is but loosely tightened, allows adjusting the cylinder part into a desired, correct working position in relation to the holder, in which position the screw joint (13) is finally tightened.
