DETECTION OF MECHANICAL STRESS LIMITING EFFECTS OF CRANE STRUCTURE DEFORMATION

The paper presents a construction design and results of laboratory tests so-called mechanical stress detectors, which can be used to detect the deformation steel structure crane amplify signal from effect skewing, is included among occasional loads acting on crane. values relative elongation detectors corresponding magnitude instantaneous tensile force were obtained by conducting experimental tests. Detectors known extent installed two-girder overhead bridge, where they measured axial forces generated during controlled bridge. In practice, recorded individual make it possible regulate speed drive wheels thus eliminate, in relatively short time, undesirable effects deforming bridge friction sides rail heads.
