Separate steering Always switch off the separate steering when driving a rigged truck crane.
There are two steering modes with separate steering.
– Driving around corners
When separate steering is switched on, the steering angle is larger than for
normal steering mode – the turning circle is smaller.
– Crab travel mode
When separate steering is switched on, you can turn the wheels of the front and
rear axle lines in the same direction – the truck crane drives sideways.
Switching to separate steering
• Select and confirm the symbol for the desired
steering mode.
–The symbol (4) indicates the selected steering
mode, e.g. Driving around corners.
– The symbols (5) become red – steering
unlocked – separate steering is switched on.
