12.7.9 Slewing with rigged counterweight
You may only slew the superstructure with a rigged counterweight if the
truck crane is supported by a sufficient outrigger span and the permissible
working radii are observed. Otherwise the truck crane will overturn during
slewing.
The current rigging mode is registered by the RCL code set, and the RCL
disables the slewing operation if it is not permitted.
The following table specifies (depending on the counterweight and outrig-
ger span) whether slewing the superstructure is:
– Permitted
– Only permitted for certain working radii
– Disabled (with the correct rigging mode).

Danger of overturning when slewing with an incorrectly set RCL!
The RCL only disables the slewing operation if you have entered the RCL
code correctly and if the RCL is not overridden.
Therefore always check before slewing whether the RCL code valid for the
current rigging mode is displayed.
This prevents slewing operations being released within impermissible
ranges and the truck crane from overturning.
G
Danger of overturning when slewing with the hand-held control!
Crane operations are not monitored by the RCL whilst the hand-held con-
trol is connected!
Always check whether a sufficient outrigger span has been set for the
rigged counterweight before slewing.
This prevents the truck crane from overturning during slewing due to
excess counterweight mass.
