Palfinger PC 3800, Operating Manual

Preparing for crane operation
When supporting the crane choose an operating station from where you may view the complete
support movement range. Always keep moving crane components in view. No persons and objects are
allowed to be in the movement area of the stabilizer outriggers / stabilizer cylinders.
The outrigger beams and stabilizer cylinders need to be operated separately on both sides. To do so,
alternately use both operator stations.
Fully extend the outrigger beams (mark must be visible).
Stabilizing sequence
The crane stabilizers are designed for absorbing only the crane load! If the vehicle is lifted completely
during crane operation, the crane support can fail.
Danger!
If the vehicle is lifted partly or completely when on the stabilizers the
stabilizing system will be under significantly higher load. This may
lead to damage and the vehicle may tip over when the crane is being
operated.
This creates an acute risk of fatality for the operator and others.
Never lift up the vehicle!
It is prohibited to lift the vehicle until the wheels are
unloaded. This overloads the support system and
reduces the braking effect.
