Title
(EN) A CRANE GRAB HEAD
(FR) TÊTE DE BENNE PRENEUSE DE GRUE
Abstract
(EN) A crane grab head (100) comprising a pair of jaws (102;104), a power source for moving the jaws, and a connector (116) for connecting the grab head (100) to a crane, wherein each jaw (102;104) comprises at least one tooth (110) for engaging with an object. Each jaw (102;104) is driven by a respective hydraulic/pneumatic cylinder (108a;108b) which is slideable linearly to move the jaws (102;104) between open and closed positions. The width of the grab measured between the extremities of the jaws (102;104) in the closed position is more than 1500mm. The separation between a horizontal plane passing through the top of the uppermost cylinder (108a;108b) when the head (100) is held freely in normal use and a parallel plane passing through the lowermost edge of the lowermost tooth (110) is less than 250mm.
(FR) La présente invention se rapporte à une tête de benne preneuse de grue (100) comprenant une paire de mâchoires (102 ; 104), une source d'énergie destinée à déplacer les mâchoires, et un connecteur (116) destiné à raccorder la tête de benne preneuse (100) à une grue, chaque mâchoire (102 ; 104) comprenant au moins une dent (110) destinée à venir en prise avec un objet. Chaque mâchoire (102 ; 104) est entraînée par un vérin hydraulique/pneumatique respectif (108a ; 108b) qui peut coulisser de façon linéaire afin de déplacer les mâchoires (102 ; 104) entre une position ouverte et une position fermée. La largeur de la benne preneuse mesurée entre les extrémités des mâchoires (102 ; 104) en position fermée est supérieure à 1 500 mm. La séparation entre un plan horizontal passant à travers la partie supérieure du vérin le plus haut (108a ; 108b) lorsque la tête (100) est maintenue librement lors d'une utilisation normale, et un plan parallèle qui passe à travers le bord le plus bas de la dent la plus basse (110), est inférieure à 250 mm.
