Device to actively control the vibrations of an articulated arm (10) consisting of a plurality of segments (12-17) each comprising at least its own actuator (22) associated with a hydraulic drive circuit including a block valve (30). At least one of said actuators (22) is associated with an auxiliary control circuit (23) of the vibrations, comprising at least a sensor (54) able to detect the vibrations and/or the position of one or more segments (12-17), a processing unit (28) to process the signals of the sensor/sensors (54) and a pump (24) commanded by the processing unit (28) and cooperating with said block valve (30). The auxiliary control circuit (23) is associated with the hydraulic drive circuit. |
