# Modern Design of Carrier for Overhead Conveyor
## 4 Conclusions  
In this article, the design process of a modern carrier and the advantages of using it were described. The main purpose was to reduce weight and thus increase usability, increase efficiency, and reduce power consumption in wheel production. Today, due to the higher price of electricity, a window is opening for the use of computing technology for the design of modern carriers that reduces the consumption of electricity.  
More advanced computational methods such as topological optimization are ideally used in the first design phase, but they also bring their advantages in the case of the reconstruction of existing devices. Another option is to use machine learning and generative design [39]. The positive effect on weight is very fundamentally linked to production technology, where methods that were previously not applicable are nowadays definitely common in technical practice. It is the advantages of these methods that need to be taken into account in the design of the carrier. In this case, it is mainly the use of sheet metal cut-outs. Nowadays, for example, 3D printing is also often used, which, however, does not make economic sense for this application.  
The use of a lighter carrier has a very positive impact on the wear of the overhead conveyor and the consumption of electric energy. Both ultimately have an impact on the now much-discussed carbon emission footprint. Of course, in addition to the ecological impact, this has a primarily economic impact.  
Another positive impact of the new carrier is the impact on maintenance with regard to the number of operators required to change the carrier. Due to the lower weight and better shape, the number of changeover workers was reduced from three to two. This has a major impact on reducing maintenance costs and also on the speed of carrier replacement.  
In general, it can be said that the optimization of the conveyor and carrier has had a very positive impact on the entire production line and on the economy and efficiency

of production. It is definitely a good idea nowadays to use modern methods in carrier design to achieve a modern carrier design that is more efficient. This is confirmed by the information from this solution, where a new carrier that is more effective is also cheaper to produce than modifying an existing design.
