Title
(EN) CUTTING TIP AND TOOL
(FR) BEC ET OUTIL DE COUPE
Abstract
(EN)
A cutting tip (10) for a mechanical excavator comprises a tip body (11) having a tip axis, a generally pointed distal end (12), a proximal end (13) spaced from the distal end along the tip axis, and a circumferential wall (14) which is non-symmetrical about the tip axis which diverges outwardly from the distal end towards the proximal end. The non-symmetrical circumferential wall comprises a plurality of axially extending ridges (15) and intermediate faces (16) disposed between the ridges.
(FR)
L'invention porte sur un bec de coupe (10) pour une excavatrice mécanique, lequel bec comprend un corps de bec (11) ayant un axe de bec, une extrémité distale globalement pointue (12), une extrémité proximale (13) espacée de l'extrémité distale le long de l'axe de bec, et une paroi circonférentielle (14) qui est non symétrique autour de l'axe de bec, qui diverge vers l'extérieur à partir de l'extrémité distale vers l'extrémité proximale. La paroi circonférentielle non symétrique comprend une pluralité d'arêtes (15) s'étendant axialement et de faces intermédiaires (16) disposées entre les arêtes.
