| Abstract: | An optimal design of the prestressed box maingirder in a 10-ton and 10-metre gantry crane was made,with the SUMT method applied to the work.According to the results thus obtained,optimal parameters of the maingirder cross-sections were given. In comparison with the original design, its weight can be reduced by 17.6% if optimized. |
