Abstract: Finite software was used to research the A5 Gantry Cranes designed by a company, whose span was 83 m. The research results indicate that the deflection of girder oversteps the formulations of General purpose gantry cranes (GB/T14406-93), coupled with a big lateral displacement. After a simple modification of the structure design for the rigid legs, the deflection of girder and the lateral displacement have reduced by 69.2% and 62.6%, respectively.
