The Conveyor Technology Planning department (PWG-P/F) at Volkswagen AG, headquartered in Wolfsburg, Germany, had commissioned PSI Technics to analyze and evaluate the operation of a vertical material lift in a vehicle body warehouse. The successful cooperation was aimed at developing a new positioning standard for similar vertical lifting systems.
Volkswagen AG, Wolfsburg, Germany
Motion analysis was used to determine the system's current motion profile, which provided a basis for determining optimization potentials. All existing loading conditions and motion sequences were simulated in a virtual model using finite element methods (FEM), multi-body models and controller modeling. The results were verified against the actual operation of the system and illustrated the benefits of using an intelligent positioning controller.
The retrofitted vertical lift fulfills and exceeds all of the client's expectations regarding cycle times, stability, reduced mechanical wear and power consumption. As calculated during virtual modeling the system's mechanical stress was reduced by more than 15%. At the same time, power consumption decreased and the cycle times were reduced by 3 seconds. These results were achieved by using the ARATEC Positioning Solution System with time-optimized motion paths and accurate positioning.

The ARATEC's FLP6000AOC software reduces mast oscillations – even of highly dynamic stacker cranes – to a minimum. The test setup shows that the ARATEC Positioning Solution System with enabled FLP6000AOC compensates for mast oscillations in near-real time, even when the oscillations are caused by external disturbances.
