The transportation system includes a supporting platform composed of upper and lower plates wherein the caster wheel partly extends from the upper plate and wherein the bearing casing can be mounted on the bottom plate. The swivel caster is completely mounted in a device having an opening with a rim that can be connected on the upper plate such that replacement of a swivel caster can be carried out solely by removing the device from the upper platform.
