Abstract

L'invention concerne un élément d'usure pour un équipement d'excavation particulièrement adapté pour être utilisé avec une tête de coupe de drague comportant une surface de butée incurvée qui vient en butée avec une surface de support incurvée complémentaire sur la base. Les surfaces de support incurvées sont aptes à maintenir un contact sensiblement complet l'une avec l'autre sous une charge transversale. La base et un adaptateur sont, en outre, munis d'une pluralité d'arrêts complémentaires pour résister à un mouvement relatif entre eux.
