1. A method for stabilizing at least one frame part of a forest work unit having a plurality of frame parts, wherein the method comprises the steps of:

  • determining a first component of a moment applied to the at least one frame part of the forest work unit by a payload carried by the at least one frame part to be supported of the forest work unit, the first component acting about a longitudinal rotation axis of the forest work unit;

    determining on the basis of at least the first component of the moment applied by the payload to the at least one frame part to be supported a magnitude and direction of at least one support moment required for stabilizing the at least one frame part;

    generating and adjusting the required support moment to a magnitude and direction with at least one actuator to stabilize the at least one frame part; and

    applying the required support moment to the at least one frame part.
