A condition of at least one structural part () of a working machine () is determined by determining a computational position of the first structural part (') on the basis of the computational model of the working machine () and determining an actual position of the first structural part (′) by detecting means (). The condition of the at least one structural part () is determined on the basis of the difference between the computational position of the first structural part () and the actual position of the first structural part ().

A condition of at least one structural part (&#x2033;) of a working machine () is determined by detecting () a force of a changing magnitude to a first structural part (') or a structural part connecting the first structural part (&#x2032;) to the second structural part (&#x2033;), determining () a change in the position of the first structural part with respect to the second structural part as a function of the force detected, and determining () the condition on the basis of the change in the position of the first structural part with respect to the second structural part as a function of the force detected. At least a slope of the change in the magnitude of the force is detected.

The invention relates to a method in a weighing system, in which method the mass of the bundle is weighed and recorded during both loading % and unloading mof the bundle, during loading, the total loading mass mis calculated from the mass mof one or more bundles weighed during loading and corrected using a correction factor C, the total unloading mass mis calculated from the mass mof one or more bundles weighed during unloading, with the aid of the said total loading mass mand total unloading mass m, a new corrected value Cj+1 is calculated for the correction factor Cin order to adjust the weighing for the loading of the next load K. The invention also relates to a corresponding software product, an arrangement, and a material-handling machine.

The invention relates to a detector arrangement and method for determining a mutual position or a mutual state of motion of at least two structural parts of a mobile work machine. The arrangement comprises detectors configurable to determine at least in one direction of measurement at least two different measured variables in order to determine at least structural-part-specific position or state of motion information for each direction of measurement. The arrangement further comprises a data processing means for receiving measurement signals describing measured variables as well as for determining a mutual position or state of motion of the structural parts on the basis of the structural-part-specific position or state of motion information.

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.
