Abstract
The article provides an analysis of typical and unique defects and damages of crane beams, which is a continuation of the series of articles by the authors about defects and damages of industrial buildings. Previously, articles on typical defects of industrial buildings have already been published: ground bases, foundations, reinforced concrete columns, metal columns, vertical connections and wall panels. Most of the defects are explained by photos. At the end of the article, an analysis of the characteristic zones of defect formation in the metal crane beams of industrial buildings is given, which allows laying the foundation for the development of an automated control system (ACS) for the life cycle of an industrial building.

Summary
Сквозные отверстия - часто встречаемое повреждение, причинами появления могут быть механические повреждения в результате прожига электросваркой или в результате сквозной коррозии элемента Развития данное повреждение не имеет, техническое состояние балок с погибами вертикальных ребер оценивается как работоспособное или ограниченно работоспособное. Техническое состояние балки следует признать ограниченно работоспособным, устраняется повреждение путем пескоструйной очистки металла от производственной пыли и продуктов коррозии с последующим усилением опорных ребер. Причиной подобного дефекта является неверное проектное решение, поскольку искривление опорных ребер во взаимно противоположных направлениях было выявлено на всех стыках подкрановых балок вдоль эстакады
