9.1 Axle load calculation
An axle load calculation is required to optimize the
overall vehicle (vehicle and body). It is only possible to
match the body to the truck if the vehicle is weighed
before any work on the body is carried out. The
weights measured by weighing form the basis of the
axle load calculation.
The moment theorem is used to distribute the weight
of the equipment on the front and rear axles. All
distances relate to the center front axle (theoretical
center). Mark the weight with mathematically correct
signs and enter them in the table. The result will assist
you in choosing the optimum positioning of the body.
It has proved useful to make the following
calculations:
Weight
+ (plus) is everything when the vehicle is laden
– (minus) is everything that the vehicle can unload
(weights)
Axle distance
+ (plus) is everything behind the center of the front
axle
– (minus) is everything in front of the center of the
front axle
Calculate the weight distribution on the front and rear
axle using the formula:
Ö

HA
= Change in weight on rear axle in [kg]

= Component weight in [kg]
a = Axle distance to theoretical center of
