    Abstract. One of the key elements of convector workshops of metallurgical enterprises is crane beams, which ensure the movement of crane equipment, loading of the charge, transportation of metal buckets and a number of other technological operations. Crane beams are subjected to significant dynamic and temperature loads, so their operation and timely maintenance are critically important to ensure durability and safe operation in difficult metallurgical production conditions. As a result of repeated cyclic application of the load, fatigue cracks appear and gradually develop in the supporting areas of the ball, which can eventually lead to the complete destruction of structures. Fatigue failure, unlike static failure, can occur even at low stresses, which do not exceed half of the static strength. The article analyzes the operation of the crane beam of the converter shop at the pig iron overflow site with a heavy duty overhead crane. The results of research and development work on the repair (reinforcement) of crane structures are presented. The defects of the beams under consideration are systematized, a method for restoring its bearing capacity and extending its service life is proposed.
    Keywords: crane runway beams, converter shop, crane runway operation, steel structures, fatigue damage, durability of the structure
