ance with the Lifting capacity table ;
à Entering the rigging mode, p. 11 - 36.

G
Danger of overturning if the truck crane is free-standing!
The superstructure of free on wheels truck cranes may only be rotated if
the counterweight rigged on the turntable does not weigh more than 7.6 t
(16,700 lbs) and the radius permitted in the working area is maintained according
to Lifting capacity table.
In this way you prevent the truck crane tipping to the rear when slewing the
superstructure.
G
Danger of overturning if the truck crane is free on wheels and the RCL is
overridden!
If the RCL code for working free on wheels has been entered, when the working
radius is reached the RCL prevents those crane movements that would reduce
the radius any further. This is in order to provide stability to the rear.
The truck crane will overturn if you override the RCL and reduce the working
radius any further.
