Abstract

Dispositif de protection pour le capot d'une pelleteuse mécanique, permettant de protéger ledit capot contre tout dommage lorsqu'il entre en contact avec une plate-forme porteuse d'un camion-benne, et facilitant l'entretien d'un moteur. Des dispositifs de protection latéraux (10, 11) sont prévus à droite et à gauche d'une partie terminale postérieure d'un corps pivotant supérieur (3) sur une pelleteuse mécanique de telle sorte qu'ils dépassent d'un capot (6), vus de l'avant et des côtés d'une partie postérieure, et présentent un hauteur (h), du sol jusqu'à leur bord supérieur, qui est supérieure à la hauteur (H) de la face inférieure d'une plate-forme porteuse (21) d'un camion-benne (20). Un contrepoids (12) est prévu sur une partie inférieure et postérieure par rapport au corps pivotant supérieur, de telle sorte qu'il dépasse par une distance (c) du capot, et un dispositif de protection postérieur (13) est prévu au-dessus du contrepoids de telle sorte qu'il dépasse par une distance (d) du capot. Ce dernier est conçu pour se déplacer de façon élastique vers le haut et vers l'arrière.
