Abstract

L'invention est relative à un procédé de détermination des emplacements des deux vérins hydrauliques de commande 18, 19 de deux bras articulés, le premier bras 6 sur le bâti 4 d'un engin de travaux publics, le deuxième bras 8 sur le premier bras 6. Ces deux vérins 18, 19 sont attelés entre le bâti 4 et le deuxième bras 8, l'un 21 des axes d'attelage d'un 18 des vérins étant distinct de l'axe d'attelage 22 de l'autre vérin 19 sur le même élément 8. Une application est la réalisation d'une chargeuse efficace.
