Abstract
A method and arrangement are for managing a tree handling system for a forest machine. The method includes obtaining sensor data that represent a current loading on the tree handling system and determining a key indicator that describes a measured value that is representative of the risk of partial damage based on the current loading. A current partial damage value can be compared with a normative partial damage value for a normative operating state to determine a change that would cause the current partial damage value to return to or approach a level corresponding to the normative partial damage value. The change can be executed by an actuator, which is coupled to a control unit, that limits hydraulic flow to at least one execution means to limit the loading of the tree handling system to a pre-determined maximum loading value.
