Control panel steering system
To manoeuvre the truck accurately, it is provided with an advanced steering system.
This steering system (also called
rear axle steering
) provides the use of four different steering
programs, which are distinguished from each other by the difference in steering characteristics of the
rear axles:
1.
Small turning circle
: In this mode, an extra small turning radius is possible;
2.
Manual
:
In this mode, the position of the rear axle(s) is set manually;
3.
Crab steering
:
In this mode, all steered axles are steered in the same direction;
4.
Wall steering
:
In this mode, it is possible to drive away from an obstacle with minimum
swing of the back of the truck.
When using the
control panel steering system (47)
, the steering system must be in
off-the-road mode
.
CAUTION!
For all steering programs counts that the crane must be in transport position.
A steering program may NEVER be active while driving the vehicle with the crane
folded out.
The transversal differential lock may also NEVER be active when a steering
program is active.
