You know you want to haul
bigger loads, but to do so you have to determine several factors. Do I
need extra weight on the front end or a longer wheelbase? Which one is
the right decision depends on the application, and to determine how
much additional weight you can carry with either of these
modifications, use the following calculator.
This calculator abides by the
SAE J2512 recommended practice of keeping 50% of the front axle weight
on the ground.

If you were buying a new truck, you
could simply select the rear axle that would carry your desired load.
However, if you are looking to buy a used truck, these specs have already
been chosen. To calculate the lifting load of a truck in which you
know the capacity of the rear axle, use the following calculator.

information
Front Axle Weight =
(Actual
weight on front axle)
Rear Axle Weight =
(Actual
weight on rear axle)
Wheelbase = (From
axle to axle*)
Overhang = (From
axle to point of lift*)

Fill-in this
information
Rear Axle Weight =
(Actual
weight on rear axle)
Rear Axle Rating = (Axles
maximum load rating)
Wheelbase = (From
axle to axle*)
Overhang = (From
axle to point of lift*)

These values are
calculated
Maximum Lifting Load = (How
much
you can lift)
Rear axle Load (laden) = (Minimum
rear axle size)
|
|
This value is
calculated
Maximum Lifting Load =
(How much you can lift before
exceeding your rear axle rating)
