12.7.12 Slewing with rigged counterweight
Slewing with a rigged counterweight is only permissible when:
– The necessary outrigger span is rigged
– The respective RCL code is shown
– The permissible working radius according to
Lifting capacity table is main-
tained
For slewing with rigged Mega Wing Lift:
à Mega Wing Lift operating instructions.
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 from being released within impermissi-
ble 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 whenever the hand-held
control 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.
