An automated shuttle warehouse without a lift or other expensive customization seemed to be impossible - until now. The Fraunhofer Institute for Material Flow and Logistics presents an innovative solution to this problem: the »RackRacer«. The new climbing shuttle moves autonomously in horizontal and diagonal directions - without a lift or additional rails. This process is enabled by so-called »crawler elements« which support themselves on specific climbing or supporting spots. By using this technique the shuttle has the ability to store items or take them out of stock autonomously at any position inside the rack. Inside the rack motions towards the storage location can be conducted without indirect routes. This makes the »RackRacer« a genuine revolution in intralogistics and a reasonable alternative to existing solutions, such as stacker cranes or shuttle-lift-systems.
