A blade 11 acting as a spring is fixed to one face of the main slideway body 3, via each of its ends at points which also constitute the axes 12 of rotation of two end rollers 4b. A central roller, not aligned with the end rollers, swivels on the blade and thus exerts, on one rim of the rail 2, a bearing force which opposes the bearing force of the other rollers. Application to slideways for refrigerating warehouses (depots). <IMAGE> |
