Longitudinal/
transverse differ-
ential locks
With an 8 x 8 x 8 drive, the drive of the 2nd axle line is switched on and off
together with the longitudinal differential locks.

• Stop the truck crane.
For switching on and off, the current speed needs to be under about 5 km/h
(3 mph).

Leave the transverse differential locks switched on only for as long as nec-
essary. Always switch off the transverse differential locks before driving on
a firm surface.
