In this paper, a calculation technique has been developed to ensure the stability of tower cranes. The technique allows us to comprehensively take into account the main operating factors in the crane operation mode - lifting load, wind load, dynamic forces, the weight of the crane itself and the support conditions. Based on the results of numerical modeling, crane displacements, equivalent stresses, support reactions, and forms of stability loss were studied. The critical load and stability limit were precisely determined using the load–displacement diagram, and the dependence of the stability coefficient on the boom length allows a preliminary assessment of dangerous operating modes. Computational work on the research methodology was carried out at ANSYS.
The proposed methodology is intended for use at the stages of design, installation and operation of tower cranes and is aimed at improving the safety of construction work.
