The present invention relates to a new adjustable wheeled device carrying any kind of luggage, said wheeled device providing an adequate steadiness and securing a luggage from suddenly overturning. This is attainable by increasing the distance between its two wheels in several ways, as follows: 1) by increasing telescoping both wheel axle lengths of the present invention, on either side of a luggage (Fig. 1, 2); 2) by lifting up the folding arms of the wheeled device, properly jointed; 3) by adding several coupling parts, secured by means of pressing plates (Fig. 3) or suckers (Fig. 4); a wheel axle length may be fixed or variable (Fig. 4, No. 21); 4) by providing a luggage with the proper recesses (Fig. 5, No. 11) for housing both wheeled fittings (Fig. 5, No. 4) and on the other hand by providing a luggage with the proper solid recesses (Fig. 6, No. 5) for both wheel axles and, thus, transforming a luggage into a vehicle when it is pulled and 5) in combination with any of the preceding ways.
