DEVELOPMENT OF A CONTROL SYSTEM FOR A GRAB CRANE

This article discusses the development of a control system for a 20-ton gantry crane equipped with a grapple. The primary focus is on creating an effective control mechanism for the crane's electric drive using modern Computer-Aided Design (CAD) systems. The article begins with a description of the control object and its structural diagram, establishing a foundation for further analysis. It then explores existing solutions for modernizing the control system, including the selection and justification of the most rational option. Based on the chosen components, the article details the development of the electrical schematic and the design of the electrical panel using the KOMPAS-Electric software. Additionally, a 3D model of the panel is presented, created in KOMPAS-3D. To assess the reliability and efficiency of the selected equipment, a thermal calculation is conducted using specialized software APM FEM. The results of this study aim to enhance the operational characteristics and safety of lifting equipment.
