When smaller dimension from product length and width is more then the
determination length of small or large, use overhang ratio. Following
example is for small product overhang ratio. Smaller dimension from
product length and width divided value call "Product overhang ratio."
For example: Use following situation for overhang
Maximum loaded length from pallet stopper with front direction. 1600
Maximum loaded length from pallet stopper with side direction. 1400
Pallet origin point
Pallet length
Pallet width

Large product overhang
Small product overhang
Length of determining small or large
Product length
Product width
Compare the product length and width, smaller one is 480mm. It is smaller
than the length of determining small or large. Use smaller product overhang
ratio of determining overhang. This value is "80."
480 ÷ 6 =80
Next, compare the pallet overhang and value "80" which we found in above
formula, "80" is most smallest value. It means overhang for this product is
product overhang, not pallet overhang. Add "80"mm to pallet dimension.
1200+80×2=1360
1100+80×2=1260
These values are inside of the maximum product dimension and it is OK.
Therefore range for creating stacking pattern is as followings.
Pallet L side = 1360
Pallet W side = 1260
