Handling unit dimensions, example E

Example

The parent handling unit has a user-defined external packaging item called Pallet. The parent handling unit has one child level consisting of 25 child handling units. Five child handling unit have a user-defined internal packaging item called Box A and 20 child handling units have user-defined internal packaging item Box B. The dimensions of the individual packaging items of the handling unit are as follows:

Dimensions	Pallet	Box A	Box B
Width	1 m	0.5 m	0.25 m
Length	1 m	0.5 m	0.4 m
Height	0.2 m	0.5 m	0.3 m
Floor Space	1 m2	0.25 m2	0.1 m2
Volume	0.2 m3	0.125 m3	0.03 m3

Using the dimensions of the previous example, the dimensions of the parent including the child handling units are as follows:

Width

The width of the parent handling unit is equal to the width of the external packaging item Pallet, 1 m.

Length

The depth of the parent handling unit is equal to the depth of the external packaging item Pallet, 1 m.

Height

The height of the parent handling unit is 1.825 m. The surface areas of the pallet and the boxes determine whether the boxes must be stacked to fit on the pallet. The value in the Height field of the Handling Units (whwmd5130m000) session shows the height of the stacked boxes of both types added with the height of the pallet. If the pallet carries internal packaging items or items with different heights, LN uses the aggregated surface areas of both types of boxes, the surface area of the pallet, the height of the box or item with the greatest height to determine the dimensions of the handling unit. LN calculates the height of the handling unit as follows:

1. Divide the aggregated floor space of the internal packaging items, no matter the type of packaging item, by the floor space of the external packaging item
2. Multiply the result with the height of the internal packaging item with the greatest height
3. Add the result of step 2 to the height of the external packaging item

The aggregated floor space of Box A is 5 * 0.25 = 1.25. The aggregated floor space of Box B is 20 * 0.1 = 2. The aggregated floor space of Box A and Box B is 1.25 + 2 = 3.25. The surface area of the pallet is 1 m2. 3.25 / 1 = 3.25. In the example, the height of Box A is 0.5, which is greater than height 0.3 of Box B. Therefore, you must multiply 3.25 by 0.5, the result of which is 1.625. Finally, add this result to the height of the pallet: 1.625 + 0.2 = 1.825.

Net Weight

The gross weight is the aggregated weight of the items contained in the child handling units and the aggregated weight of the external packaging items of the parent and the internal packaging items (of either type) of the child handling units. The net weight is the aggregated weight of the items contained in the child handling units.
