A method for stabilizing an articulated vehicle, which articulated vehicle comprises at least a front frame structure and a rear frame structure, and a frame joint structure, which is arranged to couple the frame structures to each other and to allow them to rotate both in relation to each other, away from the normal position, as well as at the same time around an axis, which is substantially parallel to the longitudinal direction of the articulated vehicle. In the method a supporting force is maintained, which force affects between the frame structures and resists the rotation of the frame structures away from normal position, and the maximum of said supporting force is controlled in such a manner that it is dependent on the difference of rotations at least when said difference is increasing and at least when said difference is static.

Stabilization of an articulated vehicle

A cabin structure for a working machine includes a substantially transparent cabin element equipped with a bottom part having a seat for the operator of the working machine, a display and a controller for controlling the operations of the working machine. The cabin structure also includes a control mechanism for tilting the cabin element in relation to the frame of the working machine in both XZ and YZ directions. The cabin element is arranged to be substantially stationary in relation to the frame of the working machine, and the seat and controller are placed on a working base placed above the bottom part of the cabin element. The control mechanism is pieced positioned between the working base and the bottom part of the cabin element. The control mechanism can also rotate the working base around the Z axis.
