To enable the slewing movement, you must
reduce the working radius correspondingly,
e.g. to 16 m (52.5 ft) for slewing into slewing
range

.
– When telescoping or derricking
The diagram remains at the current posi-
tion. The displays (
2 ) move a corresponding
distance up or down.
In a shutdown range ( 1 ) a movement
towards the shutdown limit is continually
reduced until reaching a standstill.
The speed reduction occurs in the same
manner as with the Standard slewing range
type;

p. 11 - 54.
Special case – disabled range
A slewing range can be disabled in certain
cases.
If for example, an outrigger span ( 1 ) is rigged
and operations are to be performed at the
right side, with large counterweight combina-
tions, a small working radius and a small load
it is possible for the stability towards the rear
to become endangered within the slewing
range
1
.
The range
1
in the diagram would then be
empty and slewing out of range
4
would be
stopped at the range limit ( 2 ).
In this case you can increase the working
radius – assuming this is permitted by the ena-
bled working range and the external condi-
tions. If the required stability is then present,
the slewing range
1
is enabled and displayed.
