Claim 4:
5. An apparatus according to claim 2, characterized in that in mechanical connection with the articulated connection construction on the side of the second elongated frame part is arranged a mounting structure which is arranged movable along or alongside the second elongated frame part, thereby providing for the articulated connection construction and for the first end of the first elongated frame part mechanically connected to the articulated connection construction a degree of freedom of movement along or alongside the second frame part, wherein a third driving mechanism is arranged to drive the mounting structure along or alongside the second elongated frame part, and the control system is configured to, when the first and second elongated frame parts extend essentially in parallel and as a response to a control signal to alter the mutual orientation of the first and second elongated frame parts, first operate the displacement mechanism to move the second end of the first elongated frame part a distance away from the second end of the second elongated frame part and, second, operate said third driving mechanism to drive the mounting structure along or alongside the second elongated frame part towards the second end of the second elongated frame part so as to move the second end of the first elongated frame part a further distance away from the second end of the second elongated frame part.
