Calculating axle loads:
„
Multiply the distance between storage space and front axle (A) with the
weight of the load in the storage space (G) and divide the result by the
wheelbase (R). The result is the weight of the load in the storage space on
the rear axle. Make a note of this weight and of the storage space.
„
In a second step, subtract the weight in the storage space (G) from the
weight calculated beforehand. If the result is a
positive value (example 1),
this means that the load on the front axle is reduced by this value. If the
result is a negative value (example 2), this means that the load on the front
axle is increased . Make a note of this value, too.
„
Calculate all storage spaces of the vehicle in the same way.
„
In a last step, add all weights calculated for the rear axle to the rear axle
load and add (or subtract) all weights calculated for the front axle to (from)
the front axle load.
How to determine rear axle load and front axle load is described in
section 3.2.2.
If the calculated value exceeds the permissible axle load, the load must be dis-
tributed in a different way.
If the load on the front axle is too low, the grip of the tyres on the road is
reduced (traction). This applies in particular to vehicles with front-wheel drive.
In this case, the load must be redistributed, too.
3.2.4 Roof load
Z
Measure the external distances horizontally from the centre of the front
wheel to the centre of the storage space or to the centre of the back wheel.
Example 1 Example 2
Example calculation Distance to the front axle A (A1) 450 (cm) (A2) 250 (cm)
Weight in the storage space G x 100 (kg) x 50 (kg)
Wheelbase of the vehicle R ÷ 325 (cm) ÷ 325 (cm)
Load on the rear axle
(add to the axle load) 138.5 (kg) 38.5 (kg)
Weight in the storage space - 100 (kg) - 50 (kg)
Load relief to the front axle
(subtract from the axle load) 38.5 (kg)
Load on the front axle
(add to the axle load) -11.5 (kg)
X
Do not climb onto the roof. Only use a ladder to climb up if a roof rail is
fitted.
X
Take care when stepping onto the ladder. There is danger of slipping
when the ladder is moist or icy.
X
Do not overload the roof. Road behaviour and brake reaction deteriorate
as the roof load increases.
