Abstract:
A method of loading containers in an optimum way on a load-carrying platform of a vehicle, in which a plurality of containers identical in shape are loaded in front-to-rear and left-to-right matrix arrangement symmetrically of the platform center, comprising the steps of:calculating moment weight WiÂ·i which is multiplication of total weight Wi of containers in each row distant forward by i rows from the platform center by i; calculating moment weight Wâˆ’iÂ·i which is multiplication of total weight Wâˆ’i of containers in each row distant rearward by i rows from the platform center by i; calculating the bias load ratio in the traveling direction, which is the ratio of the difference |&Sgr;WiÂ·iâˆ’&Sgr;Wâˆ’1Â·i| between the total &Sgr;WiÂ·i of moment weights of rows located forward of the platform center C and the total &Sgr;Wâˆ’iÂ·i of moment weights of rows located rearward of the platform center C relative to the sum of same (&Sgr;WiÂ·i+&Sgr;Wâˆ’1Â·i); calculating moment weight WjÂ·j which is multiplication of total weight Wj of containers in each column distant leftward by j columns from the platform center by j; calculating moment weight Wâˆ’jÂ·j which is multiplication of total weight Wâˆ’j of containers in each column distant rightward by j columns from the platform center by j; calculating the bias load ratio in the breadth direction, which is the ratio of the difference |&Sgr;WjÂ·jâˆ’&Sgr;Wâˆ’jÂ·j| between the total &Sgr;WjÂ·j of moment weights of columns located leftward of the platform center C and the total &Sgr;Wâˆ’jÂ·j of moment weights of columns located rightward of the platform center C relative to the sum of same (&Sgr;WjÂ·j+&Sgr;Wâˆ’jÂ·j); and loading the containers such that the calculated bias load ratio in the traveling direction falls within a predetermined range and the calculated bias load ratio in the breadth direction falls within a predetermined range.
