Abstract

The invention elates to the system for controlling the verticality of a grab bucket fitted with skids for controlling its verticality. The control system comprises first and second sensors (62, 64) for delivering signals representative of tilt relative to the vertical concerning the longitudinal axis of the frame in a first plane and in a second plane containing the longitudinal axis and extending parallel to the main faces of the frame and orthogonally thereto; third sensors (66) for delivering a signal representative of twisting movement of the frame about the vertical; processor means (70) for processing the signals delivered by the sensors and for deducing therefrom information concerning the tilt and/or twisting of the frame; control means (78, 80) for controlling actuators (V1 to V6) for generating commands for said actuators as a function of said tilt and twisting information; and manual means (74) for applying said commands to the said actuators.
