Effects on
the axle loads
Observe the effects on the axle loads when towing a trailer. The axle loads
of your truck crane change in the following manner when operating with
central axle trailers:
– For every 100 kg (220 lbs) of drawbar load, the axle loads on the 1st axle
line are reduced by 74 kg (163 lbs).
– For every 100 kg (220 lbs) of drawbar load, the axle loads on the 2nd and
3rd axle lines are reduced by 87 kg (192 lbs).

Risk of accidents by trailer moving unintentionally
Before coupling or uncoupling the trailer, it must be secured with the trailer
parking brake as well as with chocks to prevent it rolling away. Ensure that
it is still possible to swivel the front axle of the trailer.
G
Risk of accidents when coupling the trailer
No one may be between the truck crane and trailer when coupling the two
vehicles.
G
Risk of accidents from unexpected acceleration
When you move slowly to the trailer, the transmission automatically shifts
into manoeuvring mode. If the warning buzzer sounds, release the acceler-
ator immediately.
If you do not release the accelerator, the electronics will engage
automatically within a few seconds. The truck crane could accelerate unex-
pectedly and people might be crushed between the trailer and the truck
crane.
