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 and
2nd axle lines are reduced by 36 kg (80 lbs).
– For every 100 kg (220 lbs) of drawbar load, the axle loads on the 3rd to
6th axle lines are reduced by 43 kg (95 lbs).
G
Risk of accident 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 from rolling away. Ensure
that it is still possible to swivel the front axle of the trailer.
G
Risk of accident when coupling the trailer
No one may be between the truck crane and trailer when coupling the two
vehicles.
G
Risk of accident 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
unexpectedly and people might be crushed between the trailer and the
truck crane.
