Abstract
Loading and unloading operations are an integral part of the technological process of construction. Cranes of various types are mostly used to per-form these works. In modern industrial and civil construction, tower cranes of the stationary type are widely used, which are used in the construction of vari-ous types of structures and buildings. Today, it is impossible to imagine a panorama of a city or a fairly large rural village without the upward, light openwork silhouettes of tower cranes. They are clearly visible against the back-ground of new residential buildings, wherever progressive changes are taking place, where con-struction is underway. More than 200,000 tower cranes are used on construction sites in the coun-try today. But when using tower cranes, special attention must be paid to their operation in adverse condi-tions, because they are mechanisms of increased danger. One of the important factors in the unfavora-ble conditions during the full-scale Russian inva-sion of Ukraine was the shock waves that arise as a result of missile strikes. These shock waves, in turn, cause air pressure and oscillations on the Earth's surface and cause certain seismicity. To ensure trouble-free operation and increase the reliability of tower cranes, it is important to take into account dynamic loads, which are sever-al times greater than static loads, when calculat-ing structures and components of their working equipment. Ensuring the stability of stationary tower cranes, especially in the conditions of martial law, is one of the important theoretical and practical tasks. The most important aspect of solving this problem is ensuring stability under the conditions of air shock waves, which cause the effect of dy-namic loads on the metal structures of the crane.
