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.

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.
