Abstract

L’invention porte sur un dispositif (5) de levage auxiliaire ainsi que sur une grue comportant un tel dispositif et sur un procédé utilisant une telle grue. La grue (10) à flèche (1) télescopique comporte un membre fixe (2) dans lequel coulisse au moins un membre mobile (4). Le dispositif de levage auxiliaire (5) comprend un boîtier (7) fixé au membre fixe (2) de la flèche (1) et au-dessus d’une charge (20) à soulever, et renfermant une première poulie (8), dite de renvoi, d’axe transversal à une direction de coulissement de la flèche (1). Le dispositif (5) comprend aussi une élingue (6) fixée par à un point d’accrochage (15) d’une extrémité du membre mobile (4) et qui est fixée par son autre extrémité à la charge (20) à soulever. L’élingue (6) passe ainsi sur la poulie de renvoi (8) de telle sorte que le coulissement du membre mobile (4) provoque par l’intermédiaire de l’élingue (6) le soulèvement ou l’abaissement vertical de la charge (20). Figure à publier avec l’abrégé : Fig. 1The invention relates to an auxiliary lifting device (5) as well as to a crane comprising such a device and to a method using such a crane. The crane (10) with telescopic boom (1) comprises a fixed member (2) in which slides at least one movable member (4). The auxiliary lifting device (5) comprises a housing (7) fixed to the fixed member (2) of the boom (1) and above a load (20) to be lifted, and containing a first pulley (8), referred to as a return, with an axis transverse to a sliding direction of the arrow (1). The device (5) also comprises a sling (6) fixed by a hooking point (15) of one end of the movable member (4) and which is fixed by its other end to the load (20) to be lifted. The sling (6) thus passes over the return pulley (8) so that the sliding of the movable member (4) causes via the sling (6) the vertical lifting or lowering of the load (20).
