With a ship-building gantry crane serving for 18 years as the study object , the paper conducts analysis on the structure and load response for the crane drum with the strain electric measuring method .The measuring point forming 90°to the drum section with the maximum bending moment is set to determine the stress change rule of the drum under typ -ical working conditions .The study result provides guidance for design and safety evaluation of the drum structure of the sle -wing pillar gantry crane.
