APPLICATION OF ENERGY-SAVING TECHNOLOGIES IN THE CREATION OF RELOADING COMPLEXES OF THE INCREASED OPERATIONAL RELIABILITY

The theoretical issues of energy-saving technologies for servicing studios such as Handymax, Suezmax, Panamax, increasing the requirements for the quality and performance of transshipment complexes are investigated. The problem of reducing material consumption and energy consumption, increasing the reliability of gantry cranes at the stage of their design or modernization by rational determination of the geometrical and weight parameters of the boom system, minimizing the fluctuation of the load during its horizontal movement, taking into account dynamic loads from the action of wind and the appearance of ice in winter, improving and selection of materials for the manufacture of elements of the boom system. A method is proposed for calculating the dynamic component of the wind load under different conditions of action of the wind force, taking into account the technology of transshipment operations, windage of cargo and the vector nature of wind loads. Recommendations on the choice of material and protective coating for the metal structures of gantry cranes in an aggressive environment of ports are presented.
