Method and an arrangement for managing and controlling the lifetime of a tree handling system for a forest machine
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.

To reduce the risk of damage and costly downtime when handling timber, the following features are proposed; that the load gate (10) is constructed to allow connection to one end of a means (90, 91; 35) that provides yield-mounting and that limits motion, that the suspension arrangement (20) comprises a support frame (36) arranged on the chassis (3) constructed to allow the connection of a second end of the said means (90, 91; 35) that provides yield-mounting and that limits motion, that the load gate (10) is supported on the support frame (36) in such a manner that it can move freely relative to the chassis (3) in its principal plane through the interaction between the said means (90, 91; 35) that provides yield-mounting and that limits motion arranged between the load gate (10) and the support frame (36).

LOAD GATE AND A VEHICLE EQUIPPED WITH SUCH A LOAD GATE
The invention concerns a load gate for a vehicle such as a forwarder or similar and intended to limit a forward end gable of a load compartment (4) formed from load bunks (5) and stakes (6), and comprising outer frame sections (28, 29, 31, 32) that, joined at their ends, form a surrounding principally square or rectangular outer frame, an inner structure that extends between the frame parts and with which the outer frame parts are mutually joined. A load gate that, without deviating from the requirement of comprehensive protection, improves the overview of the operator of the load compartment from the driver's cabin comprises a central principal gate section (25) and side gate sections (26, 26') arranged on each side of this, and the combination that the central principal gate section (25) demonstrates a lattice inner structure formed from a number of elements (30) that are placed in a sequence and with an orientation that differs from that of the load bunks (5), while the side gate sections (26, 26') demonstrate a lattice inner structure formed from a number of elements (30) that are placed in a sequence and with an orientation that differs from that of the stakes (6).

Method and device for delimbing a tree trunk (60) in a compliant gripping state defined by a set of limbing knives (18, 24, 26, 28) enclosing the trunk. The limbing knives are repeatedly adjusted through a control unit (46) for adaption of the gripping state to a varying thickness of the trunk when the trunk is advanced between the knives for the delimbing of the trunk. The invention comprises entering a desired compliance (D1) of the gripping state in the control unit (46), detecting an actual compliance (d) of the gripping state, and performing each adjustment of the limbing knives via the control unit until the actual compliance (d) corresponds to the desired compliance (D1).
