The transient response of the truck crane structure due to winch operation when the loading beam is operated in the vertical direction from the crane frame axis has been examined by modal analysis. The transient vibration strain in the lower beam were observed in an actual track crane and numerical simulations were carried out. Then, relationships between the winch operation and transient vibration strain levels were presented for the various operation patterns of the winch.
