MAXbase slewing
range type
If the Standard slewing range type has been entered; Ã p. 10 - 59.
Permissible working range display
The displays apply to the confirmed rigging
mode.
Example of a permissible working range
Assume that the slewing range (1) lies between
-35° and -145°.
The corresponding curve has the same colour
e.g. the curve (3).
The working range in slewing range (1) ends at
the maximum possible working radius (4).
Reduction of the working radius increases the
enabled load along the curve (3) up to the maxi-
mum possible load (2).
There has to be enough reeving for this load. The
speed reduction due to reeving occurs in the same
manner as with the Standard slewing range type;
à p. 10 - 60.
Slewing ranges display
The display is same in all four slewing ranges.
