This article presents an engineering design of a mechanical rack system along with strength analyses of its main load-bearer parts. The designed mechanical rack system is intended to be mounted in a production hall for storage of rod material with total length of 6 m. The whole structure of this equipment is welded and made of steel profiles. It consists of a main load-bearing part, which comprises a central beam and horizontal beams and four draw-out shelves on each side, which are arranged four levels. Every individual shelve is able to carry the mass of 3.0 t. As the solved rack system is not standardized but designed in compliance with specific requirements of a customer, we had to support the structure carrying capacity with strength calculations. Structural calculations were realized by means of numeric finite element method. Strength analyses were performed for the maximum load cases.
