Transportation system comprising a large number of platforms which can be displaced along guides and a smaller number of displacement devices which can be coupled to and uncoupled from the said platforms. Each displacement device comprises a linear actuator comprising a moving part and a stationary part. The stationary part comprises a laminated plate assembly with coils, and the moving part comprises a structure with permanent magnets, such as neodymium magnets. On the linear actuator, there may be a further linear actuator, so that movement in two directions is possible. A transportation system of this type can be used in a parking garage for positioning vehicles. |
