Abstract

L'invention concerne une benne à coquilles articulées sur des pivots intérieurs. La benne suivant l'invention est du type à coquilles articulées à l'intérieur. Chaque coquille présente deux bras dirigés vers l'intérieur et articulés sur la partie fixe 17 du corps de la benne en des points situés dans la région de la coquille opposée. Chaque coquille porte à son extrémité supérieure et extérieure 15 une articulation qui reçoit une bielle 16 elle-même reliée à une partie mobile 18 du corps de la benne La partie 15 de chaque coquille forme également une butée qui rencontre une butée fixe 19 solidaire de la partie 17 du corps de la benne pour éviter de fatiguer les articulations lorsque la benne frappe le sol. L'invention s'applique aux engins de manutention ou de terrassement.
