Abstract

L'invention concerne un appareil de levage (10) destiné à être utilisé sur un trou d'homme (1), comprenant un mât de support (12) et une grue à flèche (14) reliés à un angle donné par rapport à une partie d'extrémité supérieure (16) du mât de support (12). La grue à flèche (14) présente un élément avant (18) pointant vers le haut et s'étendant sur un côté du mât de support (12), ainsi qu'un élément arrière (20) présentant une partie d'extrémité arrière (22) s'étendant d'un autre côté du mât de support (12). Une barre de liaison (24) relie l'élément arrière de la grue à flèche (14) au mât de support (12). L'appareil comprend également un mécanisme de poulie (30) monté sur la grue à flèche (14) et présentant un câble (32) coopérant avec l'élément avant (18) de la grue à flèche (14) pour lever un objet à partir du trou d'homme (1). Dans un mode de réalisation préféré, l'appareil comprend une barrière de sécurité (40) destinée à entourer au moins partiellement le trou d'homme (1), et à empêcher l'entrée accidentelle dans celui-ci, le mât de support faisant partie de la barrière.
