The current steering angle of the wheels is displayed.
Always switch off the separate steering when driving a rigged truck crane.
There are two steering modes with separate steering.
– Driving around corners:
When the separate steering is switched on, the steering angle is larger
than for normal steering mode – the turning circle is smaller.
– Crab travel mode:
When the separate steering is switched on, the truck crane drives side-
ways if you turn the wheels of the front and rear axle lines in the same
direction.
The symbols show the current steering angle:
