Stabilizing of forest work unit

摘要

A method for stabilizing at least one frame part of a forest work unit involves determining a moment applied by a payload of the forest work unit to a frame part to be supported and determining a magnitude and direction of at least one support moment needed at least for stabilizing the frame part on the basis of the moment applied by the payload to the frame part to be supported. An arrangement for stabilizing at least one frame part of a forest work unit comprises means for carrying out said determinations.

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.
