Transport system for an elevator or lift

A translation and/or transportation system comprising:

• a movable structure for transportation,
• a guide,
• a skid integral with the movable structure and slidingly coupled to the guide along a sliding axis,
• wherein 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, and
• means—or a device—for generating without contact with the guide a force counteracting an external load impressed on the centering member,
• the load-countering 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,
• the skid comprising an auxiliary magnetic field generator for attracting or repelling the guide with a load-counteracting force directed along a direction orthogonal to a plane passing through the longitudinal axis of the guide, or in a direction orthogonal to the plane containing the guides if there are two guides,
• the auxiliary magnetic field generator being movably mounted in the skid to be able to move relative to the guide coupled to the skid so that the amplitude of the load-counteracting force can be adjusted.
