Influence of the Crane Load and Measurement Speed on the Properties of the Magnetic Field of the Girders

Abstract

Abstract The girders of the crane or the jib of the crane are situated at high heights, which prevents the free and continuous measurement of their stresses. Unfortunately, these elements are most exposed to high stress and damage during their use. The article presents the research methodology with the use of the magnetic metal memory method of the overhead crane girders. Diagnostic tests utilizing the crane movement mechanisms to move the magnetometric sensor along the tested surface of the girder were proposed to improve and automate measurements. The article attempts to investigate effect of the device load and speed of Hp measurements with a magnetometric sensor.
