The load and the finite element model of an end carriage for an overhead traveling crane are discussed. A solid model is created through a 3D design software, and calculated by a commercial finite element software. Through the analysis and calculation, the deformation, maximum stress and maximum displacement value of the end carriage can be obtained. Meanwhile, the stress and displacement of every element on the end carriage can be obtained. The simulation results show that the intensity and the stiffness of the end carriage are adequate. Based on the analysis results, the real-time modification of the end carriage can be achieved.
