Abstract

Dispositif de manutention d'une plaque lourde telle que marbre ou granit sur une table de travaiL Ce dispositif comprend une chambre 4 pouvant être alimentée en fluide sous pression par un tuyau flexible 5, et constituée par l'assemblage d'une plaque métallique de base 6 et d'une membrane souple 7 sur laquelle repose une plaque 14 supportant la pièce à manutentionner. L'introduction de fluide sous pression dans la chambre 4 gonfle la membrane qui soulève la plaque 14 et la pièce. Des ouvertures 8 d'évacuation du liquide aménagées dans la plaque de base 6 permettent la formation entre celle-ci et la table d'un coussin de fluide sur lequel on peut faire glisser le dispositif et la pièce qu'il supporte. L'invention facilite la manutention des lourdes plaques de pierre dans les marbreries et graniteries.
