The invention relates to a
transport system (100, 200, 300, 400, 500) for loads, comprising: at least one rail (10, 312, 314, 412, 414, 512, 514) which extends along a travel path; and at least one transport vehicle (50) having at least one wheel (12, 12A) which rests on the rail (10, 312, 314, 412, 414, 512, 514) by means of a running surface (14) having a concave cross-section, characterised in that the rail (10, 312, 314, 412, 414, 512, 514) comprises, in a curve of the travel path, a curved portion which has a circular-arc curvature about a centre of curvature (M), and the wheel (12, 12A) rests on the curved portion at an inner contact point (PI) and an outer contact point (PA), wherein the inner contact point (PI) is spaced apart from the centre of curvature (M) by an inner curve
radius (rI) and from the axis of rotation (D) of the wheel (12, 12A) by an inner rolling
radius (RI), and the outer contact point (PA) is spaced apart from the centre of curvature (M) by an outer curve
radius (rA) greater than (rI) and from the axis of rotation (D) of the wheel (12, 12A) by an outer rolling radius (RA) greater than (RI).
