The condition of metal structures of port handling machines in Ukrainian ports is alarming due to issues such as corrosion, mechanical wear, lack of modernization, limited maintenance
resources, and insufficient application of contemporary control methods. Structures that have been operational for several decades exhibit significant wear, reducing their loadbearing
capacity and increasing the risk of accidents. The humid marine environment exacerbates corrosion, while the stresses imposed on transshipment machinery contribute to material fatigue and cracking. This study explores the challenges and potential solutions related to the condition of metal structures of port handling machines in Ukraine. We identify key issues such as
corrosion, mechanical wear, inadequate modernization, and limited funding for maintenance. Specifically, we apply a combination of the analytical finite element method (FEM) and
experimental strain gauging to assess the stress-strain state of the metal structures of portal cranes. This integrated approach yields accurate data on structural conditions, crucial for ensuring operational safety and efficiency.
