  • Method and arrangement to control the operation of a wood-handling device in a work machine, and a forest machine
    Patent number: 11937554
    Abstract: A method for controlling operation of a wood-handling device in a work machine. The wood-handling device is attached through a rotation device to an end of a set of booms of the work machine to create a desired orientation of the wood-handling device for the operation. The orientation of the wood-handling device using the rotation device is tied on the basis of the operation to be performed using the set of booms. The orientation of the wood-handling device is tied to the position of the end of the set of booms. The position of the end of the set of booms is defined while performing the operation, on the basis of the position of the end of the set of booms. The wood-handling device is oriented using the rotation device, according to the said tie.

  • MOBILE WORKING MACHINE, CONTROL SYSTEM AND METHOD FOR CONTROLLING MOBILE WORKING MACHINE
    Publication number: 20230128377
    Abstract: In the solution put forth, a pressure level of a pump in a hydraulic transmission system of a hydraulic working machine, or power that is feedable to an electric drive motor of an electric working machine is monitored, and/or the rotation speed at the output of the drive motor of the working machine and the rotation of moving means of the working machine are monitored. The pressure level of the hydraulic power transmission pump, or the power feedable to an electric drive motor, is compared with a lower threshold value to detect a fault situation, and/or the rotation speed at the output of the drive motor is compared with the rotation of the moving means also to detect a fault situation. In case a fault situation is detected, the braking system of the working machine is controlled to apply the brakes.
