Abstract
L'excavateur comporte un dispositif 12 d'accumulation d'énergie muni d'un poids 13 du côté du contrepoids 11. Le poids d'accumulation 13 est suspendu verticalement à un câble 14 relié à la flèche 4 par deux poulies de renvoi 15 et 16. On obtient ainsi un allégement de la charge de la flèche grâce à l'énergie accumulée en particulier au moment où le godet 9 sort de l'eau. Ce dispositif d'accumulation peut également être réalisé hydrauliquement.
