Description

L'invention porte sur une flèche pour pelle mécanique.The invention relates to an arrow for excavator.

Le but de l'invention est d'obtenir à peu de frais, pour une flèche constituée par une partie supérieure et une partie inférieure, une régularisation des variations-du moment  The object of the invention is to obtain inexpensively, for an arrow constituted by an upper part and a lower part, a regularization of the variations of the moment

trêmes, tout en augmentant la plage d'angles de travail L'in- vention vise notamment à obtenir une position finale aussi haute que possible de la partie supérieure en partant d'un certain plan de travail inférieur déterminé Ce but est atteint du fait que la partie supérieure de la flèche, montée sur la î O partie inférieure de façon à pouvoir tourner, est reliée à la  The invention aims, in particular, at obtaining a final position as high as possible from the upper part, starting from a certain determined lower working plane. This goal is achieved by the fact that the upper part of the boom, mounted on the lower part so as to be rotatable, is connected to the

partie tournante de-l'engin, des deux côtés de l'axe de rota-  rotating part of the gear, on both sides of the rotational axis

commande est montée sur la partie supérieure de la flèche.  control is mounted on the upper part of the boom.

La figure l montre que la partie supérieure de la flèche montée sur la partie inférieure 1 de façon à pouvoir  FIG. 1 shows that the upper part of the arrow mounted on the lower part 1 so as to be able to

tourner est reliée à la partie tournante 7 de la pelle mécani-  turn is connected to the rotating part 7 of the excavator

du moment de la flèche dans sa zone de pivotement.  the moment of the arrow in its pivot zone.

La figure montre en outre que, en partant d'un niveau de travail inférieur d'un point d'articulation 10 de la charge, ce point ne se déplace pas sur une trajectoire circulaire quand la flèche est relevée, mais qu'il atteint un niveau plus élevé, par rapport à la trajectoire circulaire, dans la zone supérieure, et donc qu'un certain allongement se produit Cela permet de charger aisément même des véhicules de transport de grandes dimensions Un autre avantage est que cela peut se faire à proximité immédiate de la pelle mécanique On a ainsi une bonne vue d'ensemble et donc un maniement facile de l'engin Enfin,  The figure further shows that, starting from a lower work level of a point of articulation 10 of the load, this point does not move on a circular trajectory when the arrow is raised, but reaches a higher level, compared to the circular path, in the upper zone, and therefore a certain elongation occurs This allows to easily load even large transport vehicles Another advantage is that it can be done in the immediate vicinity the shovel So we have a good overview and therefore easy handling of the machine Finally,

il faut souligner que, avec la flèche en deux éléments, l'opé-  it should be emphasized that, with the arrow in two elements, the
