Abstract
(EN)
The present invention relates to a lifting tool for lifting a flanged, elongate body. The lifting tool includes a main body (1) and a lifting yoke (7) pivotally attached to the main body. The main body includes a flange recess with a flange interface surface and two locking segments (2a), (2b) each with a flange interface surface (19). The two locking segments (2a), (2b) are located in respective locking segment arch shaped guides (12), (14) The arch shaped guides have an arch radius centre offset from a main body centre axis (22). Furthermore, the invention relates to a method of lifting a flanged elongate body with a lifting tool for a flanged, elongate body.

La présente invention concerne un outil de levage destiné à lever un corps allongé à bride. L'outil de levage comprend un corps principal (1) et un étrier de levage (7) fixé de façon pivotante au corps principal. Le corps principal comprend un évidement de bride présentant une surface d'interface de bride et deux segments de verrouillage (2a), (2b) dotés chacun d'une surface d'interface de bride (19). Les deux segments de verrouillage (2a), (2b) sont situés dans des guides en forme d'arc de segment de verrouillage respectifs (12), (14). Les guides en forme d'arc présentent un centre de rayon d'arc décalé par rapport à un axe central de corps principal (22). L'invention concerne en outre un procédé de levage d'un corps allongé à bride avec un outil de levage pour un corps allongé à bride.
