The pier crane balance beam will fail due to overload,crack,fatigue and other reasons,which will cause the quay crane can not operate safely or even cause safety accidents.In this essay,finite element software is used to examine the compensat-ing beam of cargo crane.Through the simulation of the balance beam in the no-load and working process of the load situation,the static analysis of the balance beam,qualitative analysis of the maximum deformation of the balance beam and the maximum force po-sition and size and calculate the yield and fatigue safety factor,to test whether the failure occurs.According to the analysis results,the optimization suggestions are put forward,and the optimized ones are analyzed.After testing,the immunity eigenschaft of the texture can be gratifying,after optimization,but it also reduces production costs.Through this analysis,the weaker position of the structure can be clearly known,and certain basis can be provided for the detection and service personnel,simul furnish given con-ferment for the majorization of the formation.
