Abstract

Cette pince de manutention comprend une rainure de guidage 20 portée par le segment supérieur 13 d'une mâchoire 2 de la pince qui coopère avec un doigt de commande prévu à l'extrémité d'une tige 17 articulée sur un levier 10 articulé à son tour sur rune des deux mâchoires, la rainure 20 étant profilée de manière que, lorsque les mâchoires 1 et 2 sont soulevées, au moyen de la chaîne 12 après avoir été abaissée initialement, le doigt rencontre une butée pour entraîner les deux mâchoires 1 et 2 vers le haut en position d'ouverture tandis que, lorsqu'on soulève les mâchoires après avoir abaissé la pince, le doigt glisse le long de l'entraîneur pour laisser la tige 17, et le levier 10 s'élever librement pour que la pince puisse se resserrer sous l'effet de la traction exercée par l'engin de levage sur la chaîne 12 et les leviers 9 et 10. La pince est conçue spécialement pour la manutention de tuyaux en béton.
