Abstract

The residual life expectancy of the container crane which has been operated more or less 39 years is examined carefully, especially on the boom structure. The basic load and load combination need to be considered for to analyse the boom structure. Various parts of container crane are modeled for to analyse stress, the deflection and the fatigue. Analysis results show that the boom is stable in the stress and deflection but the boom vertical member is over the fatigue life. The rail support beam and boom bottom chord are approximately near the fatigue life. Analysis results show that the residual life of rail support beam and the boom bottom chord would be 2.2 years and 6.8 years, respectively.
