MAXbase slewing range type
If the Standard slewing range type has been entered;
à p. 11 - 57.
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 slewing range.
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 about
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 slew-
ing range (1) in which the maximum permissi-
ble working radius is smaller than the current
working radius (2), then the movement is con-
tinuously reduced until reaching a standstill.
The speed reduction occurs in the same man-
ner as with the Standard slewing range type;
