5.4.3 Freeing truck crane stuck in terrain
Rocking the truck
crane free
If the truck crane is stuck in terrain, you can try to free it by driving back and
forth (rocking it free):
If you are trying to rock the crane free, you should switch on the transverse
differential locks and the longitudinal differential lock.
• Switch to gear position D or R,
• Select a smaller starting gear with the switch lever,
• Start driving as far as you can as high as possible,
• Release the accelerator. The gears disengage,
• Let the truck crane roll in the opposite direction, as far as it will go,
• Start driving, again, as far as possible,
• Repeat driving and letting the truck crane roll back until it has rocked itself
free.
H
It is not helpful to switch between gear positions D and R, as switching to R
is only performed when the truck crane is stationary and takes a few sec-
onds. You would not be able to take advantage of the momentum generated
by the change of direction.
