Abstract:
Overhead cranes with electromagnet lifting systems are widely used in different industries. However, it is essential that these equipment be operated safely and following the proper procedures. Preventive maintenance is critical to ensure operational performance and avoid possible system failures. To ensure operational safety, it is necessary to implement a robust protection system. Analytical tools such as Pareto charts and graphs can be used to identify which overhead cranes and sub-equipment have the most critical and frequent problems. This article presents the analysis and implementation of protection systems for overhead cranes. The systems of radar mounted between the cranes that assist operators to avoid collisions between cranes working simultaneously in the same hall will be addressed. Additionally, improvements in the lifting and electrical systems, such as the replacement of support shackles for electromagnets, identified through laboratory studies, and adjustments to wear component maintenance plans obtained through FMEA analysis, will be discussed. The results obtained were consistent, reducing system failures and ensuring plant reliability and the safety of operators and transported materials. It is concluded that the adoption of preventive measures and the use of analytical tools are fundamental to ensuring operational safety and efficiency of material handling equipment in different industries
