3.2.2 Calculating the payload
The payload calculation at the factory is partly based on all-inclusive
weights. For safety reasons, the maximum permissible gross weight in
a laden condition must not be exceeded.
The maximum permissible gross weight and the weight including spe-
cial equipment fitted at the factory (actual weight) is shown in the vehi-
cle documents, but not the weight of the loaded vehicle (see sec-
tion 3.2.1). For your own safety, we recommend that you have your
loaded vehicle (with all passengers, luggage and personal objects)
weighed on a public weighbridge before you set out on your journey.
The payload (see section 3.2.1) is the difference in weight between
the maximum permissible gross weight in a laden condition and
the actual weight.

Example for calculating
the payload
Maximum permissible gross weight ac-
cording to vehicle documents
3300
Actual weight including basic equipment
according to vehicle documents
- 2720
This results in a permissible payload of 580
Conventional load e.g.: 3 persons each
weighing 75 kg
- 225
Additional equipment - 40
For the personal equipment this re-
sults in
= 315
The calculation of the payload from the difference between the maximum
permissible gross weight in laden condition and the actual weight specified
by the manufacturer is however only a theoretical value.
Only if the vehicle is weighed with full tanks (fuel and water), full gas bottles
and complete additional equipment on a public weighbridge, can the actual
payload be determined.
To do this, proceed as follows:
First only drive the vehicle on to the weighbridge with the front wheels
and have it weighed.
Then drive the vehicle on to the weighbridge with the back wheels and
have it weighed.
The individual values give the current axle loads. These are important for
the correct loading of the vehicle (see section 3.2.3). The sum of these val-
ues is the current weight of the vehicle.
The actual payload is the difference between the maximum permissible
gross weight in laden condition and the weighed vehicle weight.
This can be used to determine the weight that remains for the personal
equipment:
Determine the weight of the passengers and subtract it from the value
for the actual payload.
The result is the weight that is permitted for the actual load of the personal
equipment.
