Abstract

With the passage of time of exploitation of means of technological transport, their degradation takes place and the threat to operational safety increases. The source of development of fatigue damages of gantry crane girders are areas of stress concentration caused by loads. The subject of the publication is to determine the possibility of diagnosing potential damage sites of the overhead travelling crane (girders) by magnetic metal memory (MPM). As a result of the test with the use of the TSC-7M-16 ferrite magnetometer, stress concentration areas were determined in which processes leading to the reduction of material strength or damage to the material structure may take place. Residual tangential magnetic field distributions and normal components of their gradients were determined. A magnetogram database for the needs of girder diagnostics was created.
