The vehicle (10) is released from its stuck position by the line (12) secured to e.g. a tree (13). The belt (11), by means of the vehicle drive motor, is made to run in such a direction that the vehicle is drawn towards the tree. The device is secured to the belt by one or more hook components which engage in the belt concave sections. It follows the belt movement to its point of turning where it is automatically released. |
