ABSTRACT:
A swivel caster suitable to be mounted in a transportation system wherein the caster includes a wheel secured on a shaft by means of a first roller bearing, the shaft being attached near its ends to the legs of a swivel fork having a body or supporting element connected with a casing of a second roller bearing such that the casing can be mounted on the transportation system. 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.
