Abstract

The device has a jaw (1) intended to carry a scoop, and a support (2) coupled to the articulated arm of a hydraulic shovel. The jaw has a camshaft (31) and two semi-circular hooks coupled by two transversal bridges. The jaw is obtained from a monoblock casting with two bearing bosses traversed by two drillings that support the camshaft. The transversal bridges rigidly connect the hooks and the bearing bosses.
