The sledge comprises two skids 5, 6 articulated along longitudinal axes. The skids are securely fastened to the chassis 1 along their intermediate length zone between a quarter and a sixth of the length of the skids. The skids are elastically deformable, and comprise concave edges 19, 20. Orientation of the sledge is ensured by the inclination of the skids controlled by a handle 11. <IMAGE>
