Q: How is the balance point related to axle weights? |
A: For any given rig, any two equally heavy truckloads with the same balance point will produce identical axle weights. |
Q: For any given rig and payload weight, will the same balance point reading on Freight Seesaw always produce the same axle weights in the real world? |
A: No. In the same way that predicting the weather is not an exact science, neither is predicting axle weights. Both use mathematical models. The balance point of a pallet pattern is a mathematical model that predicts the actual balance point of a truckload, which in turn determines the loaded axle weights (given the empty axle weights). |
Q: How does the percent column work? |
A: Instead of manually entering weights for every pallet, Freight Seesaw only needs to know the average pallet weight and number of pallets for each row. When not equal to the base weight, the average pallet weight is expressed as a percentage of the base weight in the percent column. |
Q: What is the base pallet weight? |
A: When all pallets weigh the same, the base pallet weight
is just the weight of any pallet in the load. In this scenario the
percent column can be ignored.
When some pallets weigh more than others, it is usually easiest to choose the weight that appears most often to be the base weight. For example suppose a truckload has the following pallet weights: 2000 pounds (18 pallets) 1800 pounds (2 pallets) 1600 pounds (2 pallets) The obvious choice for the base weight above is 2000 pounds. Since 1800 is 90 percent of 2000, any row that consists entirely of 1800-pound pallets should have 90 in the percent column. For a row consisting of one 1600-pound pallet and one 2000-pound pallet, since 3600 is 90 percent of 4000, it would again be correct to enter 90 in the percent column. A calculator that converts pallet weights into row percentages is available here. |
