Abstract: front page image
(EN)A tubing grab assembly to retain and lift tubing, pipes, tubulars or other cylindrical objects. The assembly includes a pair of opposed jaws and a housing having a cavity. A least one of the opposed jaws has a shaft therethrough to permit rotation of the jaw with respect to the housing between a closed position and an open position. A jaw spring forces the movable jaw toward the closed position. A retractable spring trigger mechanism locks the pair of opposed jaws in the closed position.
(FR)L'invention concerne un ensemble de préhension de tubage permettant de retenir et de soulever du tubage, des tuyaux, des tubes ou d'autres objets cylindriques. L'ensemble comprend une paire de mâchoires opposées et un logement ayant une cavité. Au moins l'une des mâchoires opposées comporte un arbre au travers de celle-ci pour permettre la rotation de la mâchoire par rapport au logement entre une position fermée et une position ouverte. Un ressort de mâchoire force la mâchoire mobile vers la position fermée. Un mécanisme de déclenchement de ressort rétractable permet de verrouiller la paire de mâchoires opposées dans la position fermée.
