Abstract

La présente invention concerne un godet destiné à une chargeuse et/ou à une excavatrice/pelle mécanique/rétrocaveuse et, en particulier, un godet léger, économique et facile à fabriquer et à manipuler destiné à une chargeuse et/ou à des excavatrices. Le progrès concerne l'amélioration de la capacité de chargeuses montées sur roues qui dépend du poids et du volume de leurs godets. Il est à noter que le godet destiné à une chargeuse et/ou à une excavatrice permet spécifiquement d'obtenir une réduction du poids du godet en faisant intervenir des sections structurées creuses à la place des lourdes plaques d'acier généralement utilisées dans la fabrication de tels godets, ce qui permet d'augmenter la capacité et de faciliter la manipulation d'une plus grande charge avec la même quantité de carburant. En outre, la fabrication faisant intervenir de telles sections structurées creuses est simple et économique. Avantageusement, le progrès permet de disposer d'un godet économique et comparativement léger, destiné à une chargeuse et/ou à une excavatrice, sans influencer en aucune manière la rigidité et la durabilité requises du godet pour porter une charge, tout en améliorant la capacité du godet. Le procédé de fabrication est également plus simple.
