Preparing for crane operation 3.2-3
When being supported, the vehicle must not be lifted out of the springs in order not to overload the
support and not to reduce the braking effect.
On vehicles with air suspension ensure that the air-sprung axles are not automatically adjusted
during crane operation.
The crane support is only designed for accommodating the load
moment! Therefore never raise the vehicle by means of the
support.
Before extending the outrigger box, ensure that no persons nor objects are within the movement
range of the outrigger box and support stabilizer (for minimum distances see chapter 1.3).
In some crane models it is possible to switch between support operation and crane operation.
Before extending the outrigger box switch to support operation (either mechanically or via
pushbutton).
3.2-3 Hydraulically extendable outriggers
Before supporting the vehicle extend the outriggers to
the full width (until the yellow marking is completely
visible). Make the movements individually so that you
can keep an eye on the danger area.
3.2-4 Extending the stabilizer cylinders
If your crane has manually extendable stabilizer cylinder put them in support position. Then secure
them properly as described in chapter 4.
Extend the stabilizer cylinders from the side from
which you can see the respective movement area of
the stabilizer cylinders.
If the vehicle is fitted with an additional support extend those stbilizer cylinders as previously
described. Please observe all safety instructions concerning the support.
To avoid unnecessary oil heating move the “Crane operation / Support operation” switch lever
immediately back to crane operation after the support operation.
