1Reduction of slewing speed – can be switched
on and off
In addition to the specifications in the lifting capacity table and operating
manual supplied, the automatic reduction of the slewing speed can be
switched off under certain conditions.
1.1 Important notes
These additional pages describe only this special function.
Also observe all specifications and safety instructions in the Operating
Instructions and lifting capacity table supplied.
With reduction
switched on
Depending on the degree of utilisation and the working radius, the slewing
speeds are automatically reduced to the maximum permissible levels listed
in the lifting capacity table under the comments on slewing speed.
With reduction
switched off
If the maximum slewing speeds listed in the supplied lifting capacity table are
exceeded, the buzzer tone sounds and a warning symbol is displayed.
The slewing speed is not reduced.
GRisk of accidents due to excessive slewing speed!
Observe the specified maximum permissible slewing speeds. This prevents
the truck crane from being subjected to excessive dynamic loads, which
can lead to damage to crane sections and the truck crane overturning.
Always slow down and accelerate the slewing movement slowly and avoid
swinging loads.
When reduction is switched off, you as crane operator are responsible for
a slewing speed that is suitable the current loading case.

– Warning message display (3) – blue.
The slewing speed is not reduced auto-
matically.
If the maximum permissible slewing speed
is exceeded, the buzzer tone sounds once
and the warning message (3) is displayed –
red.
HThe entered limitations for the power unit speed of the slewing gear are still
valid and the continuous speed reductions due to the working range limiter
are still active.
Switching reduction on

The display RCL (1) shows the outrigger spans
in metres (feet).
The control units (2) indicate the outrigger
spans in per cent.
The percentage values in the enclosed lifting
capacity table and the enclosed operating instruc-
tions deviate from the percentage values actu-
ally displayed on the control units (2) as they
are based on different principles.
These additional pages give an overview for different crane types of what
per cent you have to move the outrigger beams on the control units in order
to obtain the desired outrigger span.
HDepending on the operating instructions supplied, the outrigger spans are
given as the overall width or additionally as an individual width.

In the Operating manual supplied, it is noted that special care must be taken when
telescoping in the emergency programe (1), as no automatic monitoring takes
place.
If you move the telescoping cylinder without a telescopic section (return run),
please also note all the information in these additional pages.
(A) – These specifications apply to the outermost
telescopic section (3) – on all fixed lengths.
•Always stop extending the telescopic cylin-
der (1) once the locking point (2) on the
outermost telescopic section (3) has been
reached.
There is no automatic shutdown.
(B) – If you move too far past the locking point (2),
the cylinder tube (4) will hit the main boom
head (5) at the front.
This can lead to damage which makes telescop-
ing the main boom no longer possible.
Telescoping emergency programe
Return run of the telescoping cylinder
SRisk of damage during return run of the telescopic cylinder!
Always stop extending once the locking point on the outermost telescopic section
has been reached.
This prevents damage to the boom system through a collision between the
telescoping cylinder and the main boom head.
