<p>The device has steering mechanisms (11, 12) comprising steering actuators (11a, 11b, 12a, 12b), which are connected by a connecting and disconnecting unit to normally direct a motorized vehicle in a position of securing the actuators and rotate the vehicle around a vertical axis (A) in a release position of the actuators, where the device is controlled by a normal steering system of the vehicle. A drive unit (13) rotates a driveshaft to rotate the vehicle around the vertical axis. A hydraulic system is connected to the steering system to control rotation of the vehicle.</p> |
