Preparing for crane operation

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.
In order to ensure safe operation follow the below sequence of stabilizing your vehicle:
Note!
Depending on the equipment available on your vehicle like front
stabilizer, rear stabilizers or additional stabilizers one or several
points may not apply to your model.

Extend the stabilizers until they have firm ground contact
(support pad).
1. Extend and support the additional stabilizers (left / right).
2. Extend and support the crane stabilizers (left / right).
3. Extend and support the front and rear stabilizers (left /
right).
In general it is only permitted to operate the crane with all stabilizer cylinders being on the ground.
Exception: If the crane is equipped with HPSC stability control (refer to ‘Safety equipment, HPSC
stability control’).
