Slewing-angle-dependent lifting capacity control
The slewing-angle-dependent lifting capacity control responds if the vehicles stability is threatened by
the load arm being swiveled further.
The following functions are no longer possible:
-main boom:...................................................... lowering/raising
-hinged arm abovehorizontal: .......................... lowering
-hinged arm below horizontal: ......................... raising
-extendable arm: .............................................. extending
-load arm: ....................................................... slewing
If fitted:
-rope winch: ................................................... raising
-fly jib: ............................................................. raising/lowering
-fly jib: ............................................................ extending extendable arm
Before you will be able to swivel further the load moment must be reduced by retracting the
hydraulically extendable arms.
After this the operation elements of the crane must be put to cero to release all blocked functions.
