Extend the supporting cylinders until the outrigger pads are just above
the ground.
Starting procedure
Depending on the truck crane's equipment, you can start the procedure
from the hand-held control and the
Outrigger control
units.
On the control units
•
Press the button ( 1 ) once.
•
Additionally, press the button ( 2 ).
The procedure begins.
Automatic procedure
1. All supporting cylinders are extended one after the other until the
outrigger pads touch the ground.
2. All the supporting cylinders are extended simultaneously so that none
of the wheels is touching the ground any more.
3. The truck crane is automatically levelled horizontally.
This procedure is performed:
– until horizontal alignment is reached, the lamp ( 1 ) in the centre is the
only one lighting up in measuring range 1° or
– until you let go of a button or
– until horizontal alignment is no longer possible,
e.g. when a supporting cylinder is extended as far as possible.
G
Danger of overturning if the truck crane is not level
When CCS ends the automatic alignment procedure, the truck crane is not
necessarily level.
Always check the horizontal alignment on the inclination indicator after
automatic levelling.
