FALBN_challengeThe Challenge

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.

FALBNOur Solution

The best possible tread material for this application was the polyurethane-elastomer Blickle Besthane®. The tread is characterised by its extremely low rolling resistance. Changing the Shore hardness from 92° to 96° and optimising and overwinding the tread contour permits a high load capacity together with a low swivel resistance.

The result

The sample wheels provided by Blickle passed the client’s tests with flying colours. The Blickle solution also provided the best possible energy efficiency. The client has already put in additional orders for 2018.
