Abstract
A vehicle or machine is suitable for operation on uneven or inclined surfaces, the vehicle or machine being a forest work unit and including at least three frame parts and two rotational planes, each of which rotational planes is arranged to be formed, in each particular case, on an interface between two successive frame parts of the vehicle or machine. The rotational planes are, in each particular case, planes perpendicular to the longitudinal axis of the vehicle or machine in the neutral position. The frame parts are thus arranged to be mutually rotatable in relation to said rotational plane.

1-18. (canceled)
An arrangement in a moving vehicle or machine, comprising at least three frame parts, wherein the vehicle or machine is a forest work unit and that the arrangement comprises
- at least two rotational planes,
- each of which rotational planes is arranged to be formed on an interface which separates, in each particular case, two frame parts positioned substantially successively in the longitudinal direction of the frame of the vehicle or machine from each other,
- said frame parts being arranged, in relation to each of the rotational planes, at least rotationally substantially around a longitudinal axis of the vehicle or machine or an axis in the vicinity thereof and substantially parallel thereto, and
- the mutual rotation of the successive frame parts separated by at least one of the rotational planes around said axis being actively controllable such that a frame part positioned between two other frame parts and separated by rotational planes is guided into a substantially horizontal position substantially continuously or when desired in relation to the rotation around the longitudinal axis of the vehicle or machine.
A method in connection with a vehicle or machine, wherein the vehicle or machine being a forest work unit, and the method comprising
- forming the frame of the vehicle or machine of at least three frame parts;
- forming at least two rotational planes between the frame parts;
- and
- enabling mutual rotation of the frame parts positioned, in each particular case, substantially successively in the longitudinal direction of the frame and separated by a rotational plane around a longitudinal axis or an axis in the vicinity thereof and substantially parallel thereto in the direction of the rotational plane in such a way that the mutual rotation of the successive frame parts separated by at least one of the rotational planes around the longitudinal axis is actively controllable, such that a frame part positioned between two other frame parts and separated by rotational planes is guided into a substantially horizontal position substantially continuously or when desired in relation to the rotation around the longitudinal axis of the vehicle or machine.
