A general contractor project determined that an automated guided vehicle system (AGV) was the most practical solution for handling internal material flows. The client chose a manufacturer after performing a thorough market analysis. However, the client was not satisfied with how the AGV system was integrated into the material flow layout of the future operator. The client therefore decided to develop their own AGVs. They were looking for drive wheels which were capable of handling a maximum load of 1000 kg per transport unit while maximising energy efficiency. Four drive and steering units were required for each driverless lift truck, each of which was equipped with two wheels. The client wanted to use LiFePo4 (lithium-ironphosphate battery) for energy storage.
