Abstract
A translation and/or transportation system, such as an elevator, is described comprising a movable structure for transportation, e.g. a passenger cabin or a load-carrying platform, a guide and a skid integral with the movable structure and slidingly coupled to the guide along a sliding axis. The skid is configured to stably and slidingly couple the movable structure to the guide, and comprises a centering member in contact with the guide. To attenuate the sliding friction, the skid comprises means—or a device—for generating without contact with the guide a force counteracting an external load impressed on the centering member, the load-counteracting force being repulsive or attractive on the guide, and directed in the opposite direction to the force impressed by the external load on the centering member.
