Claims: What I claim is:

1. A device adapted to facilitate the simultaneous transportation of a number of standardized load units along a groundwork by means of a support and a trolley member adapted to be introduced into the support, the improvement that the support is formed as a beam frame of rectangular configuration, the breadth and length thereof substantially corresponding to whole multiples of the breadth and the length of a standardized load unit, and which is open at least along one of its sides, the beams forming the sides of the frame being arranged in such a manner that they will form a channel at least along two parallel sides of the frame, said channel being open inwards with respect to the frame, and the trolley member includes a platform of the same general size as the said frame having marginal portions adapted to fit into the channels along the said at least two sides of the beam frame, the trolley member being provided with means for facilitating the movement along the groundwork and further means to lift the frame and the load from the groundwork.

2. The device according to claim 1, in which the movement facilitating means includes a number of wheels or rollers and the lifting means includes a number of pressure fluid rams located along the said marginal portions of the platform.

3. The device according to claim 1, in which the platform includes a further frame provided with traction means for attachment to a vehicle, said traction means being adapted, when fitted to the vehicle, to lift the adjacent end of the load carrying frame, the said lifting and transportation facilitating means including a vertically displaceable group of wheels fitted at the said further frame, at the end thereof remote from the traction means.

4. The device according to claim 1, in which the said lifting and transportation facilitating means includes one or more air cushion devices adapted simultaneously to lift the frame and to make possible a horizontal movement.

5. The device according to claim 1, in which the frame, at a distance from its end opposite to the open side corresponding to the breadth of a load unit, is provided with a cross brace.

6. The device according to claim 1, in which the frame at its top side is provided with means adapted to engage the load units in order to prevent the latter from sliding off the frame.

7. The device according to claim 2, in which the trolley is carried by wheels grouped into at least two bogies, which are mounted so as to be dirigible with respect to the longitudinal axis of the frame.

8. The device according to claim 1, in which two frames, each having one side open, are interconnected to form a unit having basically the shape of an E.

9. The device accordng to claim 1, in which two frames are interconnected with their open sides facing in opposite directions, to form a unit having basically the shape of a H.
