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
2
.
– 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;
à 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.
