Continuously growing XXL-products are reaching dimensions that can hardly be handled without innovative technological support. Therefore advances in the transport and lifting technologies are aimed at manufacturing (partly) automated assembly aids for the final assembly of large scale components. The assembly of XXL-products is similar to the construction of prototypes. The aim is to avoid constant new development and design of assembly aids by making them usable across several processes. In addition to the presentation of a method for systematization and easier choice of assembly aids in this paper there will also be presented the product development process of an assembly aid for craneless and therefore weather-independent assembly of rotor blades on offshore wind energy plants.
