LIFTING BEAM SUITED TO THE ACCURATE POSITIONING, ON A FIXED COMPONENT, OF A HEAVY SUSPENDED COMPONENT, NOTABLY BY ROTATION ABOUT A HORIZONTAL AXIS

摘要

Lifting beam (1) for positioning a component (2) about a horizontal axis (X11) of said lifting beam, comprising: • - a first beam (11); • - a second beam (12) that forms at least a circular runway about the horizontal axis (X11); • - means via which said first beam can run along said runway; and • - means (3) for securing said component to said first beam so that the centre of gravity (G) of said component is on the horizontal axis (X11).
