Display of the slewing ranges
The RCL display represents the four enabled
slewing ranges
1
to
4
in a diagram with four
regions.
The maximum permissible working radius (
5 )
is shown for each region.
Assume that the confirmed lifting capacity table
applies to the angular ranges
– ±60° to the left/right
– ±30° to the front/rear
According to the definition for the slewing angle
display (0° to the rear) the slewing range limits
would be -30°/+30°/+150° and -150°.
The
RCL
display shows an angular range of
approx. 200°. The range of the diagram is
always in the middle corresponding to the
current slewing angle (
6 ), for example,
the range
3
for 120°.
– When slewing
The displays ( 2 ), ( 3 ) and ( 6 ) remain at the
current position. The diagram ( 4 ) and the
displays ( 5 ) move to the left or right.
If the slewing movement would lead into
a slewing range (
1 ) in which the maximum
permissible working radius is smaller than
the current working radius (
2 ), then the
movement is continuously reduced until
reaching a standstill.
The speed reduction occurs in the same
manner as with the Standard slewing range
type;
