Use of 3D model in the study of tower crane stability

The article presents the results of a study of the stability of a tower crane during operation, taking into account the influence of loads on the supports. The results of comparing the distribution of loads on the crane supports determined as a result of mathematical and computer modeling during the turning and lifting of the boom are presented. An analysis of tower crane designs, installation methods and operating conditions, as well as methods for calculating their stability, shows that recently there has been a need to install cranes that can handle loading and unloading operations in confined spaces. This raises the question of how important the stability of cranes under different operating conditions and different wind loads is. In this case, the correct choice of the support circuit comes to the fore, for which it is very important to determine the loads on the support elements.
