Definitions

  • the object of the present invention was to solve the following problem:
  • the spoon is replaced by a special stone gripper. It essentially consists of three to five circularly arranged, hydraulically operated arms. The stones or blocks of iron can thus be gripped and clamped. Unfortunately, such a special gripper does not have the possibility of digging trenches or holes with its arms. It is therefore only useful for work in which stones have to be lifted practically exclusively, because otherwise a constant reassembly of this stone fer to the normal excavator bucket and vice versa would not be debatable.

Abstract

Cette pince à pierres pour pelleteuse résout un vieux problème, cest-à-dire que les grosses pierres apparaissant lors de l'excavation ne peuvent pas être levées avec la pelle normale. Ce problème est résolu dans le présent brevet avec deux bras ou parties de pince (1) additionnels, qui peuvent être montés et commandés hydrauliquement sur la pelle normale (2). De cette manière les grosses pierres apparaissant pendant le creusement peuvent être saisies et évacuées.
