Abstract

L'invention concerne un procédé et un équipement de manutention d'un nombre N de profilés en béton à précontrainte axiale. Le procédé selon l'invention consiste : a) à saisir, par leurs extrémités, les N profilés en deux lots de N/2 profilés au moyen de deux paires de bras (4) et (5) opposés deux à deux ; b) à retourner, après les avoir soulevés, chaque lot de N/2 profilés en faisant subir aux deux paires de bras (4) et (5) des mouvements de rotation (R) de sens opposés autour d'un axe longitudinal (X), parallèle aux profilés, propre à chaque paire de bras, légèrement excentré, par rapport à leur axe médian (Y), d'une distance de valeur E déterminée, de manière à disposer, après retournement, de deux lots de N/2 profilés séparés par une distance de valeur égale à 4 E.The invention relates to a method and equipment for handling an N number of axially prestressed concrete sections. The method according to the invention consists: a) in gripping, by their ends, the N profiles in two batches of N / 2 profiles by means of two pairs of arms (4) and (5) opposite in pairs; b) to turn over, after having raised them, each batch of N / 2 profiles by subjecting the two pairs of arms (4) and (5) to rotational movements (R) in opposite directions around a longitudinal axis (X ), parallel to the profiles, specific to each pair of arms, slightly eccentric, with respect to their median axis (Y), by a distance of determined value E, so as to have, after turning over, two batches of N / 2 profiles separated by a distance equal to 4 E.
