12.9.11 Slewing with rigged counterweight
Slewing with a rigged counterweight is only permissible when:
– The necessary outrigger span is rigged
– The current rigging mode is shown on the
RCL
display
– the permissible working radius according to Lifting capacity table is
maintained.
G
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.
Before slewing, always check that the current rigging mode is shown on the
RCL display.
This prevents slewing operations from being enabled within the impermis-
sible ranges, which would cause the truck crane to overturn.
G
Risk of overturning when slewing in emergency operation!
Crane operations are not monitored by the RCL whilst the hand-held
control is connected during emergency operation!
Various checks are therefore necessary, depending on the active slewing
range type, before slewing in emergency operation;
