Calculating the permissible trailer weight
C=T x Dt : (T - Dt) Example: 12 x 7.13 : (12 - 7.13) = 17.6
Dt = D : 9.81 Example: 70 : 9.81 = 7.13

C = Permissible trailer weight (tonnes)
T = Weight of tractor vehicle (tonnes)
D = D-value (kN)
DANGER:
Attach implements and trailers only to the points specified for this purpose.
Do not exceed the maximum vertical bearing load on the coupling.
Observe appropriate axle loads and weights, and follow the traffic regulations.
Make sure trailer is correctly attached. Check that the trailer brake system is
functioning. Follow the trailer manufacturers instructions!
Carry out regular checks to ensure the trailer hitch is in perfect condition, especially
when subjected to heavy loads.
The coupler is a design-approved component and may be used only for its designated
purpose.
Use only correct drawbar coupling-pin combinations. Use only the bolts provided.
When converting to a mechanical or automatic coupling, ensure that the coupling
cannot slip out of the guide rails unintentionally, by fitting a locking screw into the
bottom hole.
We reserve the right to make technical modifications. The details on the rating plate
are binding.
The maximum traction vehicle/trailer total weight of 40 tonnes must not be exceeded.
If there are different values on the trailer bracket and trailer hitch rating plates, the
lower value is the definitive value.
