The described bachelor’s thesis represents the analysis and the production of programmable overload system which is used by coastal crane Liebherr. In the bachelor’s thesis, two chapters are presented in contents. In the first part, the documentation of the existing system is studied. In this chapter, there is an explanation of each complex and the card of the overload device where various measurements on overload cards were performed. In the second chapter, the production of the product is described. The product was made because it could be used to replace the existing overload device quickly in the case of malfunctioning of the crane. This essentially reduces the costs of replacement, as the crane does not function in the case of the malfunctioning of the system. Here, the existing machine was of great assistance to me. I analyzed it previously. The goal was to produce a product which is capable of replacing the existing system. The project includes a probe simulator which replaces the role of a probe on the crane, comparative cards, and AD converter.
