Weight Distribution
Weight Distribution Analysis
Step 3. The final step is to total all of the front and rear axle weights to ensure that the axles are not overload-
ed. Table B-4 shows the assembled information in an easy to read format.
• Compare the calculated axle ground totals against the axle weight ratings to be sure that the truck is
properly specified to haul this load.
• From this, it is evident that the chassis is properly equipped for this job.
These calculations illustrate the importance of doing the weight distribution analysis. In some cases the addi-
tion of one component (for example, a liftgate) can produce a dramatic difference.
Body Length
Step 4. Your analysis may produce results that indicate an overloaded axle with a total loaded chassis weight
less than the GVW. This shows that you need to use a different body length for the truck. Each wheelbase
can accommodate several different body lengths. However, for each wheelbase and GVW one particular body
length will provide close to optimum weight distribution on both axles.
a.
Table B-3 lists Recommended Body Lengths for a particular wheelbase and
GVW. These body lengths provide the best weight distribution for the listed wheelbase.
Note:
These charts were generated assuming a plain van body with “water level”
loading. Any common additions such as lift gates or refrigeration units may
indicate a different wheelbase for a given body length. Also, different body
styles may require a different WB for a given size.
