The thesis describes the safety upgrade of a hydraulic press on a practical example. Hydraulic presses must be properly designed for safety, as they are powerful machines that can cause serious injuries if not designed properly.
In the introduction, legislation and standards in the field of safety are presented. By observing these standards, we achieve compliance of the machine with legislation (rules or directives).
In addition to directives and standards, the thesis presents an efficient software tool for calculating performance levels, which significantly simplifies and saves time during the calculation process. For easier understanding of the software, the necessary procedures to achieve the desired objective are described.
The central part of the thesis is related to the existing hydraulic press, describing the initial safety issues and the proposed measures to improve its safety.
The final part explains the determination of the required performance level and the calculation of the achieved level using the EN ISO 13849-1 standard. Using the validation process, the reliability of safety functions was verified in accordance with the EN ISO 13849-2 standard.
The aim of the thesis is to improve the safety of the hydraulic press by applying relevant standards and directives to a level that makes it suitable for use and to ensure compliance of the machine with the regulations in force in the EU (presumption of conformity).
