Freight Seesaw™ calculates the balance point for any truckload on same-sized pallets. The video and tutorial below show how it works. It may help to follow along on your mobile device.

Here is the opening screen:

When no pallets are present, tapping inside the pallet column creates a pattern with every row straight doubled (screen taps are highlighted in green):

Tapping a doubled row makes it singled:

Tapping a singled row makes it doubled:

Tapping the sideways button makes a straight row sideways:

Tapping the sideways button makes a sideways row straight:

Tapping the stacked button makes an unstacked row stacked (the row graphic only shows the number of pallets, not how they are actually arranged in the trailer):

Tapping a row with four pallets removes one pallet:

Tapping a row with three pallets adds one pallet:

Tapping a pallet dimension opens a popup menu:

Reducing the pallet length by just two inches reduced the balance point of the pattern below by eleven inches (from 264 to 253). This translates into a weight shift of roughly 2000 pounds for a heavy load (every inch of balance point is roughly the same as two inches of tandem slide). This shows why it is necessary to enter the exact pallet size.

Tapping the percent button opens a popup menu:

Select a percent:

The pallets in the first row now weigh 60 percent of what the pallets in a 100‑percent row weigh. A pattern consisting of eleven rows of 46" by 40" pallets straight doubled with 1200‑pound pallets in the first row and 2000‑pound pallets everywhere else would have a balance point of 262.

Sometimes empty pallets are used as spacers. To remove all pallets from a row, tap the row number:

In a row without pallets, tap the row number to add one pallet (or tap within the row to add two pallets):
screenshot 18
Tapping the clear button removes all pallets (the pallet dimensions stay the same):
screenshot 19
When no pallets are present, tapping a row number creates a pattern with every row straight singled:
screenshot 20
When not all rows are sideways, tapping the all‑sideways button makes them all sideways:
screenshot 21
When all rows are sideways, tapping the all‑sideways button makes them all straight. The all‑stacked button works the same way. The all‑percent button sets the percent for all rows at once.

Freight Seesaw accommodates twenty rows of freight. This concludes the tutorial. Return to top.
