Abstract (en)

The control circuit actuating member having a pair of accelerometers (10,11) mounted on the tool holder, and an electronic unit (15,16) to determine the acceleration of the tool holder, and comparing it with a pre-defined acceleration, and acting on the hydraulic circuit as a function of this comparison. The machine has a pivotable hydraulic arm (1) deployable in the work plane, and a tool holder (2), receiving a work tool (4), mounted at the end of the hydraulic arm, and actuated by a jack (5) of the control circuit. There is a member acting on the control circuit to compensate for movement of the work tool during the movement of the arm.
