Abstract

a. Mécanisme d'articulation du godet d'une pelle hydraulique. b. Il comprend une flèche formée par des poutres en caisson parallèles situées dans un même plan et qui sont associées à des poutres parallèles semblables constituant le balancier, auquel elles sont articulées par des pivots prévus à leurs extrémités. Des butées sont prévues sur le godet fixé au balancier et sont arrangées pour venir en contact avec le centre des poutres du balancier, pour assurer une plus grande robustesse. c. Concerne les engins de travaux publics et plus particulièrement les pelles hydrauliques.
