Abstract

This work complements the preventive maintenance program that is implemented for the 17 crane bridges in the rolling area of the Gerdau Diaco steel plant, Tuta plant, taking into account the importance that crane bridges represent throughout the steel manufacturing process, it is considered necessary to improve the useful life of the equipment by focusing on its critical components, taking into account their working conditions and the hours of operation with which the equipment must comply. By previously identifying the maintenance program, the necessary actions were determined to generate an improvement in this based on what is missing and in turn necessary to decrease corrective maintenance and increase equipment availability. Among these actions to be carried out, the following were carried out: filling out the equipment's resumes, determining the critical spare parts that the crane bridges have and, in turn, establishing a frequency of change for these components, based on the history recorded in the resume, in addition, periodic inspections were carried out in order to improve the availability of the overhead cranes and, finally, the standardization process of routine actions is carried out. After carrying out the aforementioned actions, the project objective was fully met, where the preventive maintenance plan was complemented. Based on the resume, the fulfillment and closing of work orders by the maintainers was monitored and as a result an improvement in the availability of the rolling crane bridges was obtained, therefore, the procedures carried out and necessary were established, in order to give continuity to its development and in a short term increase the availability of the equipment in the area.
