| Handling unit dimensionsThe method used to calculate the dimensions of a handling unit
is determined by the following factors: - The use of packaging items
- If you use packaging items, the Package Type of the packaging item. A packaging item is either of type Internal or of type External.
- The presence of child handling units for the handling unit.
Note that the calculated results are default values, you can
overwrite these values. A handling unit can have a packaging item of either type. A
parent handling unit with or without a packaging item of either type can have
at least one level of child handling units with packaging items of either type. Handling unit has internal packaging item The following list shows how the dimensions of handling units
with internal packaging items are calculated for handling units in various
levels of a handling unit structure. Parent has internal packaging item If the parent has an internal packaging item, the dimensions of
the parent handling unit are equal to those of the internal packaging item
defined for the parent, as described in Handling unit dimensions, example A. In
this example, the dimensions of the parent are equal to those of Internal packaging item of type Container. The gross
weight is equal to the weight of the packaging items of the parent and the
child handling units added with the aggregated weight of the items contained in
the handling unit. The net weight is the weight of the items contained in the
handling unit without packaging items. Child handling unit or single structure handling unit has
packaging item If a child handling unit, such as the second level child
handling units in example Handling unit dimensions, example A, or a
handling unit without a parent or children, has an internal packaging item, the
dimensions of the handling unit are equal to those of the internal packaging
item defined for the handling unit. The gross weight of the handling unit is
equal to the weight of the packaging item and the items contained in the
handling unit. The net weight is the weight of the items contained in the
handling unit without packaging items. Handling unit has more than one packaging
item If a handling unit has more than one internal packaging item,
the dimensions of the handling unit are as follows: - The width of the handling unit is equal to the aggregated
width of the internal packaging items. This means, that the packaging items lie
in a row. LN does not
provide any suggestion as to stacking.
- The gross weight is equal to the aggregated weight of the
packaging items and the items contained in the handling unit, the net weight is
without the weight of the packaging items.
- The other dimensions are equal to the dimensions of an
individual packaging item.
This calculation method is also used if the handling unit is a parent
without a packaging item whose children have various packaging items. In such
cases, the aggregated width, the aggregated weight, and the other dimensions
become the dimensions of the parent. See Handling unit dimensions, example B for an
example of how the dimensions are calculated. Parent has no packaging item, children have different types
of internal packaging items If a parent handling unit has no packaging item, and the
children have internal packaging items of different types, such as boxes of
different sizes, for the parent, the dimensions are based on the dimensions of
the packaging items of the child handling units. For information on how the
dimensions are calculated, see Handling unit dimensions, example C.
Handling unit has external packaging item For handling units with external packaging items, the dimensions
of the handling unit are determined by the surface area of the external
packaging item and the dimensions of the items carried by the packaging item.
If the handling unit with the external packaging item is a parent, the children
can have internal packaging items. If the aggregated surface area of the items or the internal
packaging items exceeds the surface area of the external packaging items, the
items or internal packaging items must be stacked on the external packaging
item. This impacts the height of the handling unit. The depth and the width of the handling unit is equal to the
width and the depth of the external packaging item. The height of the items or
internal packaging items loaded on the external packaging item is added to the
height of the external packaging item. To determine the height of the stacked
items or internal packaging items on the external packaging item, LN calculates the height
of the handling unit as follows: - Add the aggregated volume of items or internal packaging items
to the volume of the external packaging items
- Divide the result by the floor space of the external packaging
items
For an example of how LN calculates the dimensions of handling units
with external packaging items, see Handling unit dimensions, example D. Parent has external packaging item, children have items of
different heights If the parent handling unit has an external packaging item and
the children have items or internal packaging items with different heights, LN calculates the height
of the handling unit as follows: - 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
- Multiply the result with the height of the internal packaging
item with the greatest height
- Add the result of step 2 to the height of the external
packaging item
For an example of how LN calculates the dimensions of handling units
with external packaging items, see Handling unit dimensions, example E. Note The calculated heights of handling units with external
packaging items are not always the real heights of the handling units, but
approximated heights. After all, if the boxes are not allowed to jut out from
the edge of the pallet, the size of the boxes may require you to stack them
higher than the surface areas of the pallet and the boxes would indicate. For example, if the surface area of your pallet is 1 square
metre, and you have 10 boxes of 0.4 m * 0.25 m, only eight boxes would fit on
the pallet without jutting out from the edge of the pallet. Because the space
left on the pallet is insufficient, you must stack the remaining two boxes on
top of the first layer of boxes. In particular, if you put boxes or items of different sizes on
the pallet, LN only gives
approximated heights, because LN uses the height of the boxes with the
greatest height to calculate the height of the handling unit. Handling units without packaging items For handling units without packaging items, the dimensions are
determined as follows: Width The aggregated width of the items included in the handling
unit. Note that for parent handling units whose child handling units have
different width values, the width of the child handling unit with the greatest
width value is defaulted in this field. Length The depth of the item included in the handling unit. This value
is the default value taken from the Item - Warehousing (whwmd4100s000) session. Note that for parent handling units whose
child handling units have items with different depths, the default value in
this field is the added depth value of one item of each of the child handling
units. Height The height of the item included in the handling unit. This
value is the default value taken from the Item - Warehousing (whwmd4100s000) session. Note that for parent handling units whose
child handling units have different heights, the height of the child handling
unit with the greatest height value is defaulted in this field. Floor Space The value of the Length field multiplied by the value of the Width field. For parent handling units whose child
handling units contain different items, the default value in this field is the
aggregated floor space of each of the child handling units. Volume The value of the Floor Space field multiplied by the value of the Height field. For parent handling units whose child
handling units contain different items, the default value in this field is the
aggregated volume of each of the child handling units.
