Abstract : This report addresses the Palletized Loading System (PLS) M1 flatrack loading configurations for the Medium Girder Bridge (MGB) Bridge Set, Erection Set and Link Reinforcing Set (LRS). The Optimum arrangement of MGB components on PLS M1 flatracks was determined through the use Computer Aided Modeling (CAM) of both MGB components and the PLS M1 flatrack. The results of the study are that the MGB Bridge Set can be loaded onto a minimum of six M1 flatracks, the Erection Set can be loaded onto two M1 flatracks and the LRS can be loaded onto one M1 flatrack. Modified Bridge and Erection sets were also modeled. The modified Bridge Set eliminates multiple shorter bridging capabilities through the removal of duplicate end-of-bridge components. The modified Erection set eliminates simultaneous erection capabilities through the removal of duplicate erection components. The modified Bridge Set can be loaded, with less than full height loads, onto seven M1 flatracks, the modified Erection Set can be loaded onto one M1 flatrack. Modified LRS configurations were not examined. An MGB set contains two Bridge and two Erection Sets and one LRS, an MGB set composed of modified Bridge and Erection Sets still retains multiple bridging and simultaneous launching capabilities.
