In mobile cranes, the deformation of the attachment during the slewing operation affects the ease of operation. Therefore, we constructed a dynamics analysis model to evaluate the deformation of the attachment and the behavior of the hydraulic circuit during the turning operation of the crane. Furthermore, the validity of the analytical model was confirmed by measuring the deformation of the attachment during the actual swing operation by image measurement and comparing it with the analysis results. Furthermore, we conducted a seismic response analysis of the crane using this model, and clarified that no major vibration that would cause the crane to fall or collapse during an earthquake.
