This paper analyzes the dynamic behavior and stresses in a gantry crane structure during traversing motion using a simulation model. Mathematical equations for the deflection curve of a crane structure are given, and the equivalent masses and spring constants are obtained through the static condensation method. The theoreticant analysis is in good agreement with the experimental results. Non-dimensional coefficients with regard to vertical and horizontal deflections and a method of describing vertical and horizontal deflections in the static state by using those coefficients will be useful in the design of gantry cranes. In addition, the result shows that the maximum stress in a structure is sensitive to the swing angle of its load, which be a significal point of discussion in the future national and international design standards for gantry-type cranes.
