Abstract: A magnetically floating carrier system has a carriage body which is adapted to be floated by the attraction force of floating magnets acting upon the bottom surfaces of rails. The carriage body is driven by a linear motor. The rails are mounted on a framework extending longitudinally to define a track and having one side thereof supported. The carriage body is provided with a support member extending upwards at the other side of the framework to a point above the top surfaces of the framework. A pallet for supporting a load is mounted on the top end of the support member so as to be disposed over the framework. The carriage carries four magnets at front and rear parts thereof which are adapted to exert a force of attraction on the pair of rails. The magnets are mounted at both ends of two beams mounted on front and rear parts of the carriage body for see-saw motions and steering motions.
