The object of the study is handling equipment and mechanical equipment of enterprises. The purpose of the work is to increase the reliability and durability of transshipment equipment and mechanical equipment of enterprises. Research method - theoretical and experimental studies of the operation of industrial equipment during operation. Modern methods of diagnosing the technical condition of metal structures of gantry cranes are analyzed. Using the example of the "Sokil" gantry crane, technological solutions for the repair of individual sections of metal structures are proposed. The application of the "golden" rule of mechanics, which allows using one equation to obtain power transmission coefficients of lever-rod gripping devices and clamps, is substantiated. Analysis of structures, methods of installation and operating conditions of tower cranes, and methods of calculating their stability showed the need to install such cranes on limited areas, for which it is very important to determine the loads on the supporting elements and develop the design of the supporting elements themselves. Based on the analysis of the reference data, a structural diagram was drawn up and a mathematical model was developed, which takes into account the possible loads on the crane, different bearing conditions, and the rigidity of the support plane. The role of the discipline "Computer graphics" in the formation of students' spatial thinking is analyzed.
