Operation

Permissible weights and load distribution

Fig. 3

Centre of gravity indication

1

Centre of gravity of the load

Stow away / distribute the load in such a way that the centre 
of gravity of the overall load is above the longitudinal centre 
line of the trailer as far as possible. 
Keep this centre of gravity as low as possible.
Load your trailer within the limits of the permissible gross 
weight, the permissible axle loads and the permissible 
drawbar load.
Also aim for an even weight distribution in the case of a 
partial load, so that each axle is proportionally loaded and a 
sufficient drawbar load is provided.
The maximum load capacity of the trailer can only be 
obtained if the overall centre of gravity of the load is within 
the permitted range.
Restrict point loading of the cargo bed to the permissible 
extent through suitable load distribution measures.

NOTICE 

Poor/one-sided load distribution of the goods!

Severely uneven / point load distribution can lead to over-
stressing and damage to the trailer components.

Before loading your trailer, check which load objects are 

the heaviest.

Position the heaviest objects centrally on the cargo bed 

in the area of the axles.

Distribute the goods evenly over the cargo bed - avoid 

point / one-sided load distribution.
